An escalation of conflict in the Middle East could increase uncertainties, harming inflation reduction efforts and hurting growth. It has been over a year since the Hamas-led attack on Israel. Israel’s response in Gaza has resulted in widespread destruction and significant loss of life. The conflict has since expanded beyond Gaza, involving the Houthis in Yemen, Hezbollah in Lebanon and Iranian strikes targeting Israel. In addition to the awful humanitarian cost of the conflicts, the war and the possibility of its further expansion pose significant repercussions for the global economy. This article discusses three potential ways in which the current conflict and a wider conflict in the Middle East could affect the global economy. Increased geopolitical uncertainties First and foremost, an escalation of the Middle East conflict could lead to greater geopolitical uncertainties. Figure 1 shows the evolution of the geopolitical risk (GPR) and geopolitical acts (GPRA) indices (Caldara and Iacoviello, 2022) – these are text-based measures of heightened uncertainties due to adverse geopolitical events such as wars, terrorism and international tensions. (See this article for more discussion about these measures.) Following the Hamas-led attack on 7 October 2023, both the overall GPR index and its ‘war and terror acts’ component spiked strongly, to a level higher than that seen during the ISIS attack in Paris in November 2015. Both indices eased significantly in the months following October 2023 despite the continuation of the conflict. But they jumped again following Israel’s attack on southern Lebanon in September 2024. As of mid-October 2024, the GPR and GPRA remain, respectively, 21% and 35% higher than their historical averages.   What might be the consequences of such elevated levels of risk? Research tells us that higher geopolitical risk raises oil prices (Mignon and Saadaoui, 2024). It also reduces global investment and increases inflation (Caldara et al, 2022). Greater geopolitical risk has a significantly negative impact on business and consumer confidence in several advanced economies (de Wet, 2023). This is because consumers typically cut non-essential spending and businesses postpone investment decisions during turbulent times. This reduces firm-level investment, particularly for businesses with higher initial investment costs and greater market power (Wang et al, 2023). Higher geopolitical risks also reduce global trade and financial flows, causing greater volatility in capital flows in emerging markets (Kaya and Erden, 2023). Oil production cuts and higher energy prices The second way in which the Middle East conflict could affect the global economy is its impact on energy prices, both directly through production cuts and indirectly through greater uncertainties. In response to Israel’s actions against its neighbours, the Organization of the Petroleum Exporting Countries (OPEC) could reduce oil production to penalise countries supporting Israel. A similar action in the 1970s led to a significant jump in oil prices, which contributed to years of stagflation, with higher global inflation and recessions in major economies. Before Israel's attack on Lebanon at the end of September, oil prices had been declining due to falling demand, particularly from China. On the supply side, oil production had increased in Canada and the United States, countering the production cuts by OPEC, and Saudi Arabia was expected to increase oil production from December. But the situation quickly reversed following Israel’s attack on Lebanon. Oil prices jumped by nearly $10 per barrel within a week, before easing by around $5 per barrel. While the immediate oil price impact of Israel’s attack has mostly faded, the potential for higher oil (and other energy) prices still poses a risk to global inflation and economic activity (Liadze et al, 2022). To provide further context for the potential scale of this impact, we can show what would happen if oil and gas prices were to remain $10 higher for two years than the baseline levels projected in the Summer Global Economic Outlook from the National Institute of Economic and Social Research (NIESR), using NIESR’s Global Macroeconometric Model (NiGEM). The results demonstrate that the $10 rise in oil and gas prices increases inflation by around 0.7 percentage points in major economies in the first year (see Figure 2). The impact is higher in China, where the economy relies relatively more on oil imports for its strong manufacturing industries. The inflationary pressures persist for two years despite central banks’ efforts to curb inflation by increasing interest rates.   The effect of higher oil and gas prices on real GDP is shown in Figure 3. In the scenario described above, GDP would fall by 0.1-0.2% in major economies immediately. Partly due to higher interest rates, real GDP would continue to weaken for three years following the shock. After this, economic activity would start to return to base levels as oil and gas prices revert to their levels in the baseline forecast.   Increased shipping costs and supply chain disruptions A wider conflict in the Middle East could also affect the economy through higher shipping costs and supply chain disruptions. Houthi attacks on commercial ships in the Red Sea in late 2023 showed that such disruptions can have a huge impact on global trade through shipping, which comprises 80% of world trade volume. Following the rocket attacks by the Houthi rebels, some commercial shipping re-routed from the Red Sea to the Cape of Good Hope, leading to significant delays in travel times and increased freight costs. As a result, the Shanghai Containerized Freight Index – a measure of sea freight rates – rose by around 260% in the second quarter of 2024 with additional disruptions to supply chains. Our analysis shows that an increase of 10 percentage points in shipping cost inflation can lead to import prices rising by up to around 1% and consumer inflation increasing by around 0.5% in OECD countries. As Figure 4 shows, the impact of shipping costs on inflation shows its full effects over six quarters. This means that inflationary concerns could be with us for the next year and a half as a result of higher shipping costs that may emerge from any possible escalation of the Middle East conflict.   Wider economic implications and policy responses While rising geopolitical risk and increased oil and shipping costs can each individually exert upward pressure on inflation and may slow down economic activity in the global economy, the combined impacts are likely to be greater. Countries with stronger trade and financial ties to the Middle East and those that rely heavily on oil imports as an input for domestic production would be most affected. On the monetary policy front, central banks may have to take a more hawkish stance in response to rising inflationary pressures from the Middle East conflict. This could lead to higher interest rates, which would further dampen economic activity, particularly in an environment where there are already recessionary concerns in some major economies. Beyond its immediate economic implications, an escalation of the Middle East conflict could trigger large-scale displacement of people, which would increase economic and social pressures on neighbouring countries. Many countries may also have to increase their military spending in response to growing regional tensions. Given that public debt levels are already elevated in many countries due to successive shocks to the global economy over the past decade, any additional defence spending could come at the expense of public infrastructure investments that would otherwise boost productivity growth. Overall, the global economy is already underperforming as a result of the lagged effects of tight monetary policies, weaker global trade, a slowing Chinese economy and uncertainties surrounding the upcoming US election and possible changes to US trade policy. A potential escalation of conflict in the Middle East could exacerbate the situation by increasing uncertainties, harming efforts to bring down inflation and reducing global GDP growth. Over the medium and long term, it could further damage the global economy, with the possibility of refugee crises as well as increased defence spending, making the effects more complex and longer lasting. This work is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License.

한국어로 읽기 Leer en español In Deutsch lesen Gap اقرأ بالعربية Lire en français Читать на русском While the IPCC warns that we should reach the emissions peak this year, greenhouse gases released into the atmosphere will grow by 0.8%, according to the annual report from the Global Carbon Project presented this Wednesday at COP29. A cold shower in the middle of the Climate Summit, or rather, a scorching one. The independent organization Global Carbon Project (GCP), specialized in quantifying greenhouse gas emissions from fossil fuel combustion, has released its latest research. The 2024 edition of the Global Carbon Budget projects, with just over a month and a half left in the year, total annual emissions from fossil fuels to reach 37.4 billion tons of carbon dioxide (CO2). This represents a 0.8% increase compared to 2023 — with a possible error range from a 0.3% decrease to a 1.9% increase — marking a new unprecedented record at the worst possible moment. In the crucial year in which, according to the Intergovernmental Panel on Climate Change (IPCC), humanity should reach its emissions peak if it wants any chance of avoiding a global average temperature rise of 1.5°C, not only has a new historical high been reached, but there is also "no signal" that the world has reached the peak of emissions from fossil industries, warn the team behind the research presented this Wednesday. As Professor Pierre Friedlingstein from the University of Exeter’s Global Systems Institute, who coordinated the study, laments, "we still don’t see any signs that fossil fuel burning has peaked." The figures are actually more concerning, as the emissions from the "changes in land use" —which include deforestation caused by humans and their agroindustry — will add 4.2 billion tons of CO2 (GtCO2). This means that we will emit 41.6 billion tons of CO2 into the atmosphere, one billion more than last year, a period that was already a record. More coal, more oil, and more gas amid the acceleration of the climate crisis Despite significant progress in decarbonization, emissions from the three main fossil fuels will increase in 2024. The GCP’s projection is that coal emissions will rise by 0.2%, with coal responsible for 41% of emissions from fossil fuels; oil emissions will increase by 0.9%, with oil burning accounting for 32% of emissions; and gas emissions will grow by 2.4%, contributing 21% of total fossil fuel emissions. On the other hand, emissions from the cement industry, which account for 4% of global emissions, will decrease by 2.8% in 2024, mainly due to a reduction in the EU, although they will increase in China, the United States, and India, according to the research. By economic poles, while the EU — responsible for 7% of global emissions — will reduce its emissions by 3.8% this year, the United States, accounting for 13% of the total annual emissions, will only reduce them by 0.6%. China, the leading polluting power, with 32% of global annual emissions, is projected to increase its emissions by 0.2%, although the projected range suggests it could end the year with a slight decrease. Another emission hub, India, which produces 8% of greenhouse gases, will increase its emissions by 4.6% in 2024. In the rest of the world, where 38% of global emissions are produced, the forecast is an increase of 1.1%. The GCP highlights the growing importance of aviation and maritime transport in the emissions inventory: their emissions are expected to increase by 7.8%, although they remain below their 2019 level. An unprecedented concentration of gases in human history The report, conducted by researchers from over 80 institutions worldwide, including the universities of Exeter and East Anglia (UK), Ludwig-Maximilian University of Munich (Germany), and the CICERO Center for International Climate Research (Norway), provides an overview of emissions over the past decade. While they mention a certain stagnation in the past decade regarding the total greenhouse gases released into the atmosphere, the reality is that emissions continue to rise, and the previous decade (2004-2013) saw strong emission growth, with an annual increase of around 2%. Such figures mean that the concentration of CO2 in the atmosphere continues to rise. Just two weeks ago, the World Meteorological Organization (WMO) warned of a new record for greenhouse gas concentrations last year: an annual average of 420 parts per million (ppm) for CO2. In addition, surface concentrations of 1,935 parts per billion (ppb) of methane (CH4) and 336.9 ppb of nitrous oxide (N2O) were recorded. These represent increases of 151%, 265%, and 125%, respectively, compared to pre-industrial levels. "During 2023, CO2 emissions caused by massive wildfires and a possible reduction in carbon absorption by forests, combined with persistently high CO2 emissions from the burning of fossil fuels for human and industrial activities, drove the observed increase in concentrations," stated the WMO Annual Bulletin on Greenhouse Gases. Never in human history has the atmosphere been so laden with these gases, which have been released at an unprecedented speed: in twenty years, CO2 concentrations have increased by 11.4%. It is expected that atmospheric CO2 levels will reach 422.5 parts per million in 2024, 2.8 ppm higher than in 2023 and 52% above pre-industrial levels. Half-full glass However, at GCP, there is room for hope amid all the discouraging figures. "Despite another increase in global emissions this year, the latest data shows evidence of widespread climate action, with the growing penetration of renewable energy and electric vehicles displacing fossil fuels, and the decrease in deforestation emissions in recent decades, now confirmed for the first time," says Corinne Le Quéré, Research Professor at the Royal Society in the School of Environmental Sciences at the University of East Anglia. In the same vein, Dr. Glen Peters from the CICERO Center in Oslo points out that "there are many signs of positive progress at the country level, and a sense that a peak in global fossil CO2 emissions is imminent." A total of 22 countries, accounting for a combined 23% of global fossil CO2 emissions, have reduced their emissions in the 2014-2023 decade. Furthermore, countries within the Organization for Economic Co-operation and Development (OECD), in the group of wealthier nations, increased their emission reduction rates in the last decade compared to the previous one, from 0.9% to 1.4%. In the non-OECD group (excluding China), emissions growth decreased from 4.9% in the 2004-2013 decade to 1.8% in 2014-2023. However, Peters warns that "the global peak remains elusive" and emphasizes that "climate action is a collective issue, and while gradual emission reductions are occurring in some countries, increases continue in others." Another positive note is that, globally, emissions from the change in land use have decreased by 20% in the last decade, although they are expected to increase in 2024 under this category. While permanent CO2 removal through reforestation and afforestation (new forests) is offsetting emissions, it is only compensating for about half of the emissions from permanent deforestation. The GCP also issues a direct message to proponents of techno-optimism: "Current levels of technology-based carbon dioxide removal (excluding nature-based methods such as reforestation) account for only about one-millionth of the CO2 emitted by fossil fuels," they emphasize.This article was translated and licensed under CC BY-SA 3.0 ES (Atribución-CompartirIgual 3.0 España)

한국어로 읽기 Leer en español In Deutsch lesen Gap اقرأ بالعربية Lire en français Читать на русском The Paris Agreement will be ten years old in 2025. It is a good opportunity, then, to reassess the feasibility of its long-term goals and understand what they mean for the current and for the next generations. In a very optimistic scenario, if the goals of the Paris Agreement are achieved, the climate crisis will have been solved by the end of the 21st century. In the meantime, though, the crisis will worsen, as temperature overshoot is very likely to occur by the middle of the century. During the overshoot period, our planet’s average temperature exceeds 1.5°C above pre-industrial levels, which is the threshold proposed by the Paris Agreement. At the end of the overshoot period, which could last from one to several decades, the temperature will begin to fall until it eventually stabilises at 1.5°C at the turn of the century (IPCC 2023, 1810). Expectedly, the success of the Paris Agreement would greatly benefit the “post-overshoot generation”, namely the generation that will live in the first half of the 22nd century. But to ensure the success of the Paris Agreement, the generation that will live in the overshoot period – the “overshoot generation” – will have to remove an enormous amount of GHG (Greenhouse Gases) from the atmosphere. For now, though, it is unclear whether CCS (Carbon Capture and Storage) technologies will be available at a scale that might enable the overshoot generation to achieve the long-term goals of the Paris Agreement. To aggravate the problem, the overshoot generation will also probably have to rely on as-yet untested geoengineering technologies to promote their own survival. As we can see, conflicting interests of three different generations are at stake here, namely: (1) the interests of the current generation, (2) those of the overshoot generation, and (3) the interests of the post-overshoot generation. Given the unequal distribution of power across generations (Gardiner 2011, 36), it is likely that the current generation will tend to further their own interest to the detriment of the overshoot generation, even if, in the end, the climate policies enforced by the current generation do indeed fulfil the interests of the post-overshoot generation. The best possible world is one in which the goals of the Paris Agreement are achieved. Yet, depending on the choices that we make today, the best possible world could also mean the worst possible world that human beings will ever have met on our planet. That will be the fate of the overshoot generation, squeezed between the self-serving policies of the current generation and the climate hopes of the post-overshoot generation. The implications for international relations are momentous, as we intend to show in this article. Possible pathways The Paris Agreement did not establish a concrete deadline for the achievement of the goals set out in Article 2, namely: Maintain the increase in the global average temperature well below 2°C above pre-industrial levels, and make efforts to limit this temperature increase to 1.5°C above pre-industrial levels, recognising that this would significantly reduce the risks and impacts of climate change. The scientific community generally understands that the Paris Agreement aims at climate stabilization at the end of the 21st century. There are two main reasons for this. The first is a constraint imposed by our planet’s climate system. The second is a constraint imposed by agreed upon principles of justice. As for the first reason, we have to bear in mind that an immediate reduction of GHG emissions would not be followed by an immediate decline of global temperature (Dessler 2016, 91). Even if all countries decided to eliminate their respective emissions today, the global temperature would continue to rise for several decades, until it begins to recede and stabilises at the turn of the century. As for the second reason, the Paris Agreement assumed that developing countries could not immediately reduce their own emissions without compromising their own development and the prospect of eradicating poverty. Thus, the Paris Agreement also established in Article 4 that each country could continue to emit GHG until their respective emissions peaked as soon as possible. After peaking, emissions should be rapidly reduced. Thus, the attempt to achieve the goals set out in Article 2 well before the end of the 21st century might turn out to prove inconsistent with the reality of our planet’s climate system and unfair towards developing countries. The problem, however, is that the Paris Agreement did not establish a specific pathway for the achievement of its long-term goals (Figure 1). There is, indeed, a multitude of pathways, but many (if not most) of them involve an overshoot period (Geden and Löschel 2017, 881; Schleussner et al. 2016). And as there are “different interpretations for limiting global warming to 1.5°C”, there emerges the question, then, as to which interpretation could do justice to the conflicting claims of the three different generations considered as a whole, namely the claims of the current generation, those of the overshoot generation, and the claims of the post-overshoot generation (Figure 2). There has been much discussion now on the concept of a “just transition”. But this debate has focused entirely on the claims that the members of the current generation can raise against each other, and not on claims that could be raised – or presumed – across the three generations referred to above. The IPCC (Intergovernmental Panel on Climate Change) Glossary from 2023, for instance, contains a specific entry on this topic: “Just transitions. A set of principles, processes and practices that aim to ensure that no people, workers, places, sectors, countries or regions are left behind in the transition from a high-carbon to a low carbon economy” (IPCC 2023, 1806). The IPCC entry ends with some considerations regarding past generations: “Just transitions may embody the redressing of past harms and perceived injustices”. Interestingly, though, the entry says nothing about the normative implications of a just transition for future generations. A 2023 United Nations document defines the concept of just transition along similar lines (United Nations Economic and Social Council 2023, 3, 12–13). But, again, it understands “just transition” in terms of claims that stakeholders within the current generation, whether at national or international level, can raise against each other. As for the international level, the United Nations document makes the following statement concerning the concept of just transition as applied to international relations: “As countries pick up the pace of their climate change mitigation strategies, it is critical that developed countries do not transfer the burden of the transition onto developing countries” (United Nations Economic and Social Council 2023, 8). The problem, however, is that, as a matter of justice, it is equally critical that the current generation does not transfer the burden of the transition onto the overshoot generation, even if that burden, in the end, turns out to benefit the post-overshoot generation. Such an unequal distribution of burdens across three generations would certainly conflict with the requirements of intergenerational justice (Moellendorf 2022, 161–70; Meyer 2021). Overshoot generation and retroactive mitigation One might perhaps argue that no extra burden is being imposed on the overshoot generation, for the current generation is already having to face challenges that the overshoot generation, supposedly, will not have to face. The overshoot generation, one might suggest, will inherit from the current generation all the benefits resulting from the energy transition, but without having to bear the costs that the transition imposes on the current generation. The idea here is that by the middle of this century global emissions will have already peaked and will be declining at an accelerated pace, towards stabilisation at 1.5°C above the pre-industrial level at the end of this century. Thus, the overshoot generation can arguably reap the benefits of green energy, as long as the current generation remains free, at least for the time being, to emit GHG further, which is necessary to finance the human and technological development that the overshoot generation will need later. This claim, however, overlooks a crucial fact about the climate crisis – a fact that has not been given due attention in the public debate on climate policies. In a very optimistic scenario, the overshoot generation will not have the burden of reducing their own emissions because they will be able to rely on carbon-free energy. The problem, however, is that the overshoot generation will still have to retroactively mitigate the emissions of previous generations – including, of course, the emissions of the current generation. We call this process “retroactive mitigation”, for what is at stake here is not reduction and phasing out of one’s own emissions, but the removal of massive amounts of GHG, which previous generations failed to mitigate in the past. In a 2014 report, the IPCC realised that simply reducing GHG emissions would no longer be enough to preclude irreversible climate change. Removal of GHG would also be necessary (IPCC 2014, 12). The IPCC called attention to yet another problem: it was unclear whether CCS (Carbon Capture and Storage) technologies, including DAC (Direct Air Capture), could be deployed on a global scale in time to avoid a climate disaster. In a 2018 report, the IPCC was even less confident about the future development and scaling-up of CCS technologies (IPCC 2018, 136). To make matters worse, two further factors must be taken into consideration. (1) Recent studies show that there are practically no pathways left for the achievement of the Paris Agreement goals without the massive deployment of CCS (Smith et al. 2023). And (2) it has become increasingly probable that the overshoot generation will also have to deploy geoengineering technologies to cope with ever more frequent heatwaves (Moellendorf 2022, 161–70). It could perhaps be argued that afforestation and preservation of existing forests could be used instead of CCS technologies. However, the amount of land and water that would be necessary for the creation of new forests is probably larger than the amount of land and water available. Moreover, the attempt to create new forests on such a large scale might compromise the water and food security that the overshoot generation will need to promote their own climate adaptation (Shue 2017, 205). It is also necessary to take into account the amount of time new forests need to grow, not to mention the risk of fire. In this case, forests stop absorbing GHG and become GHG emitters themselves (Gatti et al. 2021). Implications for international relations In the aftermath of the Second World War, human being’s capacity to trigger catastrophic events at a global scale became increasingly apparent. As Garrett Hardin aptly put the problem in 1974: “No generation has viewed the problem of the survival of the human species as seriously as we have” (Hardin 1974b, 561). But while even realist thinkers such as Hans Morgenthau and John Herz argued for international cooperation in the face of global threats, Hardin himself advanced what he called the “lifeboat ethics”. According to Hardin, instead of engaging in international cooperation, richer states should behave like lifeboats and resist the temptation to help individuals from poorer states to cope with environmental disasters or famines. This, he argued, might undermine richer states’ capacity to secure their own survival (Hardin 1974a; 1974b). In his The Limits of Altruism: An Ecologist’s View of Survival from 1977, Hardin resumes his criticism of international cooperation to alleviate the plight of poorer states: We will do little good in the international sphere until we recognize that the greatest need of a poor country is not material: call it psychological, moral, spiritual, or what you will. The basic issue is starkly raised in a story of personal heroism that unfolded in South America a few years ago (Hardin 1977, 64). Hardin goes on to recall the 1972 Andes plane crash, turned into a feature film in 2023. Hardin suggests that the passengers who had survived the crash would not have taken the initiative to save their own lives had they not heard on the radio that the search efforts to rescue them had been called off. Hardin’s conclusion is this: “This true story, I submit, bears a close resemblance to the moral situation of poor countries. The greatest gift we can give them is the knowledge that they are on their own” (Hardin 1977, 65). Hardin, of course, does not take into consideration the extent to which richer states themselves may be responsible for the plight of poorer states. Hardin’s self-help approach to international relations is in line with political realism. But when major realist thinkers themselves addressed the question of human survival, around the same time Hardin advocated his lifeboat ethics, they came to entirely different conclusions. Authors such as Morgenthau and Herz realized that nation-states had become unable to protect their own citizens in the face of global catastrophes triggered by the depletion of the environment or the outbreak of a nuclear war. As Morgenthau put the problem in 1966: “No nation state is capable of protecting its citizens and their way of life against an all-out atomic attack. Its safety rests solely in preventing such an attack from taking place” (Morgenthau 1966, 9). In a 1976 article on the emergence of the atomic age, Herz made a similar point: “Nuclear penetrability had rendered the traditional nation-state obsolete because it could no longer fulfill its primary function, that of protection” (Herz 1976a, 101). Both Morgenthau and Herz argued for international cooperation – or perhaps even the dissolution of the system of states (Morgenthau 1978, 539) – as the better strategy to avert global catastrophic risks (Herz 1976a, 110; 1976b, 47). Herz later also theorized about the concept of “ecological threat” and argued for the development of a new interdisciplinary field, which he aptly named “survival studies” (Herz 2003; Seidel 2003; Laszlo and Seidel 2006, 2–3; Graham 2008; Stevens 2020). During the overshoot period, as heatwaves and other climate-related extreme events become more severe and frequent, people in poorer countries are likely to suffer the most. Mass migrations are likely to occur on an unprecedented scale (Vince 2022). Given the current popularity of anti-migration measures both in the United States and Europe, it is imaginable, then, that the lifeboat ethics will strike a chord with future conservative governments. That would be an error, for the assumption that governments will be protecting their own citizens by way of making their borders impenetrable to climate migrants is misleading. The “ecological threat” cannot be held back by higher walls. Lifeboat ethics will make everyone worse-off. Back in the 1960s, Martin Luther King may not have had climate change or mass migration in mind, but his words strike us as even more poignant now: “We may have all come on different ships, but we’re in the same boat now” (as quoted by former American President Barack Obama). There is only one boat, carrying three generations of hopeful passengers with equal legitimate claims to a better climate. It is a long journey. Let us not allow our only boat to go down. Final remarks The scenario in which the overshoot generation will have to live is not an encouraging one, but it is even less inhospitable than the scenario that the post-overshoot generation will have to face if the goals of the Paris Agreement are not met. It is up to the current generation to make sure that the overshoot period is as short as possible, and that the overshoot generation will not only be in a position to adapt to unprecedented climate scenarios in the history of human civilization, but also fulfil hopes of the post-overshoot generation. Figures Figure 1: Pathways compatible with the goals of the Paris Agreement (IPCC 2018, 62). FIGURE01  Figure 2: Pathways that would limit global warming to 1.5°C (IPCC 2018, 160).   Acknowledgements Marcelo de Araujo thanks Prof. Darrel Moellendorf for the invitation and the Alexander-von-Humboldt Foundation for the financial support.

한국어로 읽기 Leer en español In Deutsch lesen Gap اقرأ بالعربية Lire en français Читать на русском From January 20 to 24, 2025, the traditional World Economic Forum (WEF) took place in Davos. The organizers registered approximately 2,000 participants from over 130 countries, including around 1,600 executives from major corporations, among them 900 CEOs. The political agenda of the WEF was supported by more than 50 heads of state and government. As part of the official program, about 300 sessions were held, 200 of which were broadcast live. Press accreditation was granted to 76 media companies. For official events, 28,043 square meters of space were allocated, accommodating 117 meeting rooms and 23 lounge areas. Additionally, several participating companies (such as HSBC, EY, and Cognizant) rented additional venues separately for their own events. WEF President Børge Brende, announcing this meeting, emphasized that in 2025, due to geopolitical conflicts, ongoing economic fragmentation, and the acceleration of climate change, the forum would be held under conditions of exceptionally high global uncertainty for the first time in decades. The theme of the Forum was “Cooperation in the Age of Intelligence”. On January, WEF experts presented four reports. The first one, a traditional report and the 20th edition, analyzed the most significant global risks and threats facing the international community. The study is based on a survey of over 900 experts from various fields and covers short-term (2025), medium-term (until 2027), and long-term (until 2035) perspectives. The key risks identified for these periods include the following:- in 2025 the most serious threat for most respondents is interstate armed conflicts, followed by extreme weather events and geoeconomic conflicts, including sanctions and trade measures;- by 2027 key risks include disinformation and fake news, which undermine trust in institutions and intensify social polarization, tension, and instability, as well as an increase in cyberattacks and espionage cases;- by 2035 environmental threats are a major concern, including extreme weather events, biodiversity loss, ecosystem destruction, critical changes in Earth's systems, and natural resource shortages. Additionally, technological risks such as the negative consequences of artificial intelligence and other advanced technologies are highlighted.The authors emphasize the need to strengthen international cooperation and increase resilience to global threats. According to them, rising geopolitical tensions, climate challenges, and other risks require coordinated global action to prevent the escalation of existing issues and the emergence of new crises. The second report presents the perspectives of leading experts on the global economic outlook for 2025. They predict moderate economic slowdown, driven by geoeconomic fragmentation and protectionist measures. The most resilient economic growth is expected in the United States and South Asian countries, while Europe, China, and Latin America may face significant challenges. Inflation is projected to rise in most countries, primarily due to increased government spending and shifts in global supply chains. Most experts consider a further escalation of the U.S.-China trade war likely, along with continued regionalization of global trade, leading to the formation of more isolated economic blocs and reduced global interdependence. While experts acknowledge the high potential of artificial intelligence (AI), they emphasize the need for greater investment in infrastructure and human capital to fully leverage its benefits. The third study provides a comprehensive analysis of employment issues. The main conclusion is that ongoing changes, global trends and new technologies will cause 92 million people to leave the labor market worldwide by 2030, but will also create 170 million new jobs. One of the challenges in this regard is the need to improve skills and train for new specialties. The fourth report assesses the state of global cooperation across five key areas: trade and capital, innovation and technology, climate and natural capital, health and well-being, and peace and security. After analyzing more than 40 indicators, the authors conclude that due to heightened geopolitical tensions and instability, overall cooperation remains at the same level. However, positive trends are observed in areas such as climate, innovation, technology, and health. Davos as a Symbolic Benchmark of Switzerland Despite existing criticism, the Davos Forum remains a key platform for the annual interaction of leading figures in global politics, business, and the expert community. Without Switzerland's neutral status, the Davos Forum likely would not exist. However, it was Klaus Schwab, who founded the World Economic Forum (WEF) on January 24, 1971, who played a crucial role in transforming this event and its host location into one of Switzerland’s comparative advantages in political and economic terms. Despite his advanced age, Schwab continues to be an active ideologue and architect of Davos, moderating key discussions while fine-tuning his creation and addressing annual criticism. Yet, he has his own limitations—despite Switzerland’s neutrality and his personal reputation for impartiality, Schwab once again refrained from inviting Russian representatives, even at the level of individual entrepreneurs and experts. Such a move, rather than formal attempts to broaden participation and accessibility, could have enhanced the forum’s status. The participation of a Russian delegation would have been particularly relevant in this critical year for global politics, marked by the unpredictable presidency of Donald Trump, which is set to shape most geopolitical and geo-economic processes worldwide. Including Russian representatives could have strengthened the WEF’s competitive standing, but once again, it did not happen. The Swiss leadership highly values the opportunities that the Davos platform provides, particularly in the realm of foreign policy and, most notably, foreign economic relations. In September 2024, both chambers of the Swiss Parliament—the Council of States (the smaller chamber) and the National Council (the larger chamber)—decided to continue state support for the World Economic Forum (WEF) in Davos and allocated budget funding for the period 2025–2027. During the discussions, lawmakers emphasized that the event strengthens Switzerland’s role as a global hub for international dialogue, while also having a positive economic impact on the Graubünden region. As the host country of the forum, Switzerland actively leverages it to advance its own interests. This year, six out of the seven members of the Swiss Federal Council (Cabinet of Ministers) attended the WEF. As part of the European Free Trade Association (EFTA), Swiss Economy Minister Guy Parmelin signed free trade agreements (FTAs) with Kosovo and Thailand, bringing Switzerland’s total number of FTAs to 37. There are also plans to adapt and update the existing FTA with China. One of Bern’s key priorities remains securing an FTA with the MERCOSUR bloc. As a result, a focal point of this year’s WEF was Argentine President Javier Milei, who, during an “exceptionally warm bilateral meeting,” invited Swiss President Karin Keller-Sutter to visit Buenos Aires in 2025. The Trump Factor The opening of the current WEF coincided with the inauguration of Donald Trump, who, in recent months, has made numerous provocative statements and promises, swiftly beginning their implementation upon taking office on January 20. The U.S. president signed nearly 100 executive orders, including the repeal of 78 regulations enacted by his predecessor, Joe Biden. Among these were directives for all federal agencies and departments to address rising living costs and to end government-imposed censorship of free speech. The most significant orders included the U.S. withdrawal from the Paris Climate Agreement and the World Health Organization, as well as the declaration of a state of emergency at the U.S.-Mexico border to enforce strict immigration controls. In one way or another, the presence of the “new-old” president was felt across nearly all discussion platforms at the forum. On January 23, Donald Trump addressed the participants of the Davos Forum via video conference, outlining the following agenda:- NATO defense spending: Member states should increase their defense budgets from 2% to 5% of GDP to ensure a more equitable distribution of financial burdens within the alliance.- Trade tensions with the EU: The EU and its member states treat economic relations with the U.S. unfairly. European business regulations, including tax policies, disadvantage American companies, particularly in the tech sector, prompting Trump’s call for tariffs on European imports.- Criticism of the EU’s Green Deal: Labeling it as a “new green scam”, Trump emphasized that the U.S. would ramp up oil and gas production and expand power plant construction to become the “capital of artificial intelligence and cryptography”.- Oil prices and the Ukraine conflict: Trump suggested that lower oil prices from Saudi Arabia could help resolve the Ukraine conflict and urged Saudi leadership to take necessary steps, emphasizing their responsibility in the matter.- Tariffs on companies outsourcing production: Countries whose companies manufacture outside the U.S. will face tariffs to incentivize production relocation to American soil.- China's role in Ukraine: Trump called on China to support ending the Ukraine conflict, while stating his own efforts to mediate a peace deal between Russia and Ukraine.- U.S. domestic policy shift: A large-scale deregulation program is underway in the U.S., including tax cuts and potential elimination of diversity, equity, and inclusion (DEI) initiatives, which Trump views as discriminatory.Trump’s speech elicited mixed reactions among forum participants. His focus on protectionist policies and sharp criticism of international partners raised concerns about potential consequences for the global economy, particularly among European attendees. Additionally, his stance signaled an escalation in the strategic rivalry between Washington and Beijing, which is expected to play out through potential trade conflicts, tensions in the South and East China Seas, continued arms sales to Taiwan, and other geopolitical developments. The Europe Factor   At Davos, Europe is traditionally represented by the European Union, with the United States as its primary political and economic partner. Ursula von der Leyen, re-elected as President of the European Commission and beginning her new term on December 1, 2024, addressed the forum on January 21. Her speech largely responded to challenges outlined by Donald Trump before the WEF began, setting out the EU’s key priorities for the coming years: overcoming economic stagnation, enhancing competitiveness, and further integrating the single market across all 27 member states. A central theme of her address was the “Competitiveness Compass” initiative, first introduced in late 2024. This strategy, shaped by recommendations from Mario Draghi’s influential report, aims to drive economic reform and growth within the EU. The European Commission planned to unveil the full document by the end of January. At Davos, Ursula von der Leyen effectively introduced the concept of “Europe United” as a counterbalance to “America First” and cautioned the U.S. against igniting a trade war with the European Union. She emphasized the importance of early engagement and dialogue on shared interests, stating: “Our priority will be to initiate discussions as early as possible, focusing on common interests and readiness for negotiations. We will be pragmatic, but we will always adhere to our principles. Protecting our interests and defending our values is the European way”. At the same time, the European Commission president highlighted the high level of interdependence between the European and American economic models. She underscored that the era of global cooperation has given way to intense geostrategic competition, stating: “The world's largest economies are competing for access to raw materials, new technologies, and global trade routes—from artificial intelligence to clean technologies, from quantum computing to space, from the Arctic to the South China Sea. The race is on”. Christine Lagarde, President of the European Central Bank (ECB) emphasized that Brussels must be prepared for U.S. trade tariffs which are expected to be more “selective and targeted”, especially given the “existential crisis” facing the EU economy. She also noted that the ECB is not overly concerned about the impact of inflation from other countries, including the U.S., on the eurozone. The UK was also represented at Davos, with its delegation led by Chancellor of the Exchequer Rachel Reeves. She used the trip primarily to promote Britain’s economic landscape, focusing on the country’s political and economic stability, its business-friendly environment, and recent government efforts to reduce regulatory barriers—all under the central message: “Now is the time to invest in Britain”. However, the extent to which this narrative aligns with reality remained beyond the scope of the Forum. The true assessment was left to the executives of major corporations with whom Reeves held meetings, including JPMorgan and Goldman Sachs, discussing investment opportunities in the UK's infrastructure and green projects. Additionally, the UK delegation engaged in negotiations aimed at restoring and strengthening ties with sovereign wealth funds and private investors from the U.S. and the Gulf states. The Ukraine Factor Due to the ongoing Ukraine conflict, Davos once again served as a prelude to the Munich Security Conference, which traditionally takes place in early February in Bavaria. While the war and Donald Trump’s influence shaped many discussions, Ukraine was not the central focus of the forum, resulting in a somewhat reduced emphasis compared to previous years. Ukraine’s interests at the World Economic Forum (WEF) were primarily represented by V.Zelensky, who took it upon himself to “educate” European politicians and “interpret” the signals previously sent by Donald Trump. His focus was on defense spending, emphasizing that a significant portion should go toward supporting the Kyiv regime, the presence of foreign troops on Ukrainian territory, and the need for “real security guarantees”. In the first days after taking office, the U.S. president made several key clarifications regarding his previously stated 24-hour timeline for resolving the Ukraine conflict — this period has now been significantly extended. The reason lies in the fact that, regardless of the revocation of Zelensky’s well-known decree, Ukraine must have a head of state authorized to negotiate and officially confirm any agreements or their outcomes. As of late January, no such figure was present in Kyiv, and Washington is aware of this reality. Switzerland, while emphasizing its neutral status (despite being designated by Russia as an “unfriendly state”), consistently maintains that it provides Ukraine only humanitarian aid and diplomatic support at Kyiv’s request. At the 2024 WEF, the well-known Bürgenstock Conference was announced, which later took place in the summer. However, in 2025, no similarly large-scale initiatives were introduced. Nevertheless, discussions at the Forum once again touched on the possibility of granting Switzerland the right to represent Kyiv’s interests on the international stage. Additionally, it was reported that a Swiss-Ukrainian memorandum was signed, with Ukrainian Economy Minister Yulia Svyrydenko representing Kyiv. The agreement focuses on the participation of Swiss private businesses in Ukraine’s reconstruction efforts. V.Zelensky used Davos as an opportunity to meet with world leaders, including German Chancellor Olaf Scholz, who had recently blocked additional aid to Ukraine. However, his main competitor in Germany’s upcoming snap Bundestag elections, Friedrich Merz, was more open to the idea of support, and Zelensky also held a discussion with him. Both meetings were held behind closed doors, and no details were disclosed. Meanwhile, German Green Party leader Robert Habeck managed to avoid an impromptu conversation with Zelensky, who had attempted to engage with him on the spot. At a January 23 briefing, Russian Foreign Ministry spokesperson Maria Zakharova commented on V.Zelensky’s speeches at Davos 2025, describing them, among other things, as “narcotic madness”. The Germany Factor Germany, still holding its position as the political and economic leader of the European Union, was represented at Davos by key political heavyweights: Chancellor Olaf Scholz, Economy and Climate Protection Minister (and Vice-Chancellor) Robert Habeck, and CDU/CSU Chairman Friedrich Merz. All three have been selected by their respective parties as key candidates for chancellor in Germany’s snap Bundestag elections scheduled for February 23, 2025. Given this, it was no surprise that they used the Swiss platform as part of their election campaigns. The current head of the German government had an objective advantage: he delivered a keynote speech on behalf of Germany, in which he focused on the presence of traditional standard factors (the largest economy in the EU; efficient small, medium and large businesses; government support for investments; low level of government debt), which should help to overcome the crisis. Regarding the United States, he declared his interest in maintaining close relations with the new administration, but “without false fawning and servility”. D. Trump and his team, according to him, will keep the whole world on edge in the coming years, but the German leadership will be able to cope with this. O. Scholz's main message is that constructive European-American interaction “is of decisive importance for security throughout the world and is the engine of successful economic development”. It is noteworthy that there were many empty seats in the hall and after the Chancellor's speech there were no questions for him for a long time, which greatly surprised the moderator of the session, K. Schwab. O. Scholz's closest associate, Finance Minister J.Kukis, who was appointed to this position to replace K. Lindner, who was dismissed in early November 2024, was participating in the Forum. He was unable to provide any special pre-election support to his boss during the Forum, and did not distinguish himself in any special way. Incidentally, K. Lindner himself preferred to remain in Germany and continue to fight there for the votes of voters, which are extremely necessary for the liberals to overcome the five percent barrier and get into the Bundestag. F.Merz, who is very likely the future head of the German Cabinet, and his possible future deputy R. Habeck also sought to prove their chances of winning the elections during their speeches. O. Scholz and F.Merz organized meetings with leading representatives of German business, trying to show which of them understood their problems better and was ready to solve them constructively. Despite all their differences, they were united on one issue - the need to soften the provision on the “debt brake” enshrined in the Basic Law (Constitution) and increase support for entrepreneurs. External observers considered that F.Merz was more convincing, including regarding the transatlantic economic vector. R.Habeck unexpectedly engaged in self-criticism during the podium discussion, stating that he initially believed that the difficult economic situation in the country was due to a short-term cyclical crisis, but it turned out that this was a consequence of a long-term structural crisis. Such “self-education” of the minister cost Germany dearly. During the Forum (January 22) in the Bavarian town of Aschaffenburg, an Afghan refugee subject to deportation committed a crime, killing a child and an adult who was protecting him. This event pushed the issue of migration regulation to the top of the election campaign agenda. Unexpectedly, F.Merz found himself in a sticky situation, when his parliamentary request as the leading representative of the opposition in the current Bundestag for stricter controls at the external borders of the FRG could only count on success with the support of the unpopular Alternative for Germany and the center-left Sahra Wagenknecht Union. From Davos, Olaf Scholz traveled to Paris for a meeting with Emmanuel Macron. The French president was unable to attend the Forum due to domestic political circumstances and the need to manage the situation on the ground. The two leaders discussed the prospects for cooperation between their countries in strengthening their economic and political frameworks, as well as the European Union as a whole. None of the three key chancellor candidates managed to present a clear vision for Germany’s economic and political future, one that would be based on creativity, radical progress, technological breakthroughs, and prosperity—transforming the country into an innovation powerhouse not only for Europe but for the collective West as a whole. This means that Germany risks falling behind, failing to establish itself as an economic model capable of competing on equal terms with Donald Trump’s transforming North American economic space.Under Friedrich Merz, Olaf Scholz, and Robert Habeck, Germany faces the danger of remaining trapped in the past, relying too heavily on its post-war economic miracle—Made in Germany—which was achieved through the brilliance of ordoliberal economists and engineers. Davos 2025 made it clear that leaning solely on past achievements is no longer enough to drive a radical leap toward the future. If the German political elite, represented by the “handshake” established parties, remains in such reactionary positions in relation to the need for qualitative changes in economic policy, then the German standard will have no chance to take a leading place among the world's innovation locations. Here we will briefly indicate that, according to the estimates of the authors of the global risks report, the main ones for Germany are (in descending order): a shortage of highly qualified labor, recession / stagnation of the economy, illegal migration, disinformation, and a shortage of energy resources. They are the ones that largely determine the content of the current election campaign for the German parliament. The China Factor Among the political heavyweights representing the countries of the Global South at Davos 2025, the participation of the Chinese delegation, led by Vice Premier of the State Council of the People's Republic of China Ding Xuexiang, stands out. In his keynote speech, he emphasized Beijing's commitment to economic globalization, which is “not a zero-sum game, but a process of mutual benefit and common progress” and declared that protectionism does not lead to success, and trade wars have no winners. Among the key messages were that China is economically attractive, does not seek a trade surplus, is ready to import more competitive and high-quality goods and services to achieve balanced trade, is open to investment from foreign companies, and is ready to solve problems faced by both domestic and foreign firms. While condemning protectionism, he emphasized the importance of multilateralism and the role of the UN. While mildly critical of the “new-old” US president, he never mentioned him by name. Ding repeatedly referred to Xi Jinping, including his initiatives on global development and security. As part of the Forum, Ding Xuexiang hosted a private luncheon with top global financiers and business leaders, including the CEOs of BlackRock, Bridgewater Associates, JPMorgan, Blackstone, and Visa. Discussions centered on China’s ongoing economic reforms, efforts to stabilize the real estate market, stimulate domestic demand, and attract foreign investment. Experts noted that global business leaders responded positively to Ding Xuexiang’s statements, signaling growing confidence in China’s economic direction. In general, he fulfilled the standard mission assigned to him: to increase the international community's confidence in China's economic policy and confirm its role as a key player in the global economy. At the same time, the Forum participants remained concerned about a slowdown in China's economic growth, especially in the context of a possible increase in tariffs by the United States. The Artificial Intelligence Factor One of the leitmotifs of the forum, along with rethinking economic growth, industrial development prospects, climate and restoring trust, were discussions on the rapid development of AI, its impact on the labor market, prospects and challenges associated with the integration of this technology into various sectors of the economy. Experts identified a few trends that will emerge by 2030. AI and automation will increase the demand of enterprises for specialists in the field of AI, big data analysis, digital marketing, and cybersecurity. About half of the current skills of such employees in these areas may become obsolete, which suggests the need for timely adaptation of secondary and higher education to such a challenge. Employees whose professions will become unclaimed due to automation, especially in traditional sectors, will have to undergo advanced training programs. Special attention in the expert sessions was given to the ethical aspects of AI application and the related problems of developing the necessary standards. Issues of international cooperation took an important place, including in the context of ensuring a fair distribution of the benefits of AI application, as well as minimizing the potential risks it generates for society (for example, possible discrimination and bias in algorithms, as well as the protection of users' personal data). In terms of geopolitical rivalry in the field of AI, the global race for leadership in this area, which has already begun between the United States, China and several EU countries, was discussed. Experts pointed out the concerns of the leaders of the latter regarding the need to strengthen the positions of European companies in this area. Strategies for government stimulation of innovation and support for businesses developing AI were discussed. In addition, the participants in the discussions considered the possibilities of using artificial intelligence technologies to achieve sustainable development goals, including combating climate change, improving healthcare and increasing resource efficiency. Examples of using AI to monitor the environment, optimize energy consumption, develop new methods of treating diseases, and improve various aspects of life were of interest. *** The World Economic Forum 2025 in Davos was predictably held under the sign of global challenges, the Ukraine conflict, and increased economic competition, set against the backdrop of geopolitical and geoeconomic changes. Børge Brende, summarizing the event, accurately noted that the current time is “a moment of serious consequences and uncertainties”. This is largely linked to the return of Donald Trump to the White House. At the Forum, the United States’ priorities in strengthening national interests were outlined, including the goal of reducing import flows. This move drew criticism from the European Union and other participants, who expressed growing concerns about the escalation of trade conflicts and the fragmentation of the global economy. The President of the European Commission highlighted the prospects for strengthening the EU’s competitiveness and increasing its independence, considering the intensifying rivalry between the American and Chinese economic spheres. In this regard, representatives of China advocated for reducing trade tensions and strengthening regional alliances, while Germany emphasized the current risks facing its economic standard, outlining the difficulties of finding ways to minimize them. The Ukrainian conflict once again became one of the central topics, but with the formal support of the leaders of the collective West, delegations from the global South showed a restrained reaction to V.Zelensky's speech and messages. Discussions about AI became quite meaningful. Overall, Davos 2025 and its participants confirmed the important role of the WEF as a platform for discussing global challenges and finding constructive answers to them. The need for collective efforts to solve the most pressing issues was noted. One of B. Borge's final messages: the only way to achieve progress in solving global problems is to work together and “find solutions that will make the world a better place”. It is evident that Russia could have significantly contributed to enhancing the effectiveness of this approach.

한국어로 읽기 Leer en español In Deutsch lesen Gap اقرأ بالعربية Lire en français Читать на русском Indonesia’s inclusion in BRICS enhances the representation of the Global South and strengthens efforts to reform global governance institutions. This move positions the bloc as a stronger platform for collaboration among developing nations. On 7 January, Indonesia officially joined the BRICS grouping. In welcoming Indonesia, the Brazilian Government issued a statement, saying: “With the largest population and economy in Southeast Asia, Indonesia shares with other members a commitment to reforming global governance institutions and contributes positively to deepening South-South cooperation.” With full membership, Indonesia has become the first country in Southeast Asia to join BRICS. Currently, Thailand and Malaysia are official partners, but not full members. Indonesia’s Ministry of Foreign Affairs in its statement said the BRICS membership is “a strategic step to improve the collaborations and cooperation with other developing nations, based on the principle of equality, mutual respect, and sustainable development.” Economically, this could mean an increase of 0.3 percent growth to GDP, and the expansion of Indonesia’s access to BRICS markets. Geopolitically, it provides Indonesia a bargaining position in the global arena as well as a platform to voice the aspirations of the Global South. For BRICS, Indonesia’s membership adds another feather to its hat by bringing in greater representation of the Global South to its multipolar vision. This makes it imperative to assess the trajectory of the grouping. What started as an acronym “BRIC,” coined by Jim O’Neill in 2001 in the report “Building Better Global Economic BRICs,” the grouping was projected in the next decade to grow significantly. Founded in 2009 by the four countries—Brazil, Russia, China, and India—the bloc’s first expansion came in 2010 with the joining of South Africa. In the last 16 years, BRICS has graduated from being a popular buzz word in international politics to a significant platform of emerging economies representing the “Global South.” What is noteworthy is that BRICS is not yet a formal multilateral organisation like the United Nations, World Bank or the Organisation of the Petroleum Exporting Countries (OPEC), but increasingly there has been a greater demand among states (mostly developing countries) to join this club of emerging economies. Despite its informality, what made BRICS relevant in the international order was the 2008 financial crises, which raised scepticism and concerns over the dollar-dominated monetary system. This invariably challenged the effectiveness of the West-led Bretton Woods institutions given the suffering of the United States and Europe in the wake of the financial crisis. In contrast, the BRICS economies showed resilience. The first BRIC summit was held in Yekaterinburg in 2009, where the Joint Declaration put forward the desire of BRIC countries to develop “an incremental, proactive, pragmatic, open, and transparent dialogue and cooperation” that is “conducive not only to serving common interests of emerging market economies and developing countries, but also to building a harmonious world of lasting peace and common prosperity.” This was reaffirmed at the most recent 16th BRICS Summit held in October 2024 in Kazan. With the indicative expansion of its institutional framework and functionaries since 2009, the most significant outputs have been the New Development Bank (NDB), which provides developmental funds to countries; the Contingent Reserve Arrangement (CRA) with a resource pool of US$100 billion, which provides a mutual support mechanism for short-term balance of payments pressures, enhancing the financial safety net of member countries; and the Strategy for BRICS Economic Partnership 2025 for effective integration of BRICS enterprises into global and regional value chains. A significant milestone was the call, during the 15th BRICS Summit in Johannesburg in 2023, for the expansion of BRICS by inviting new states to join. Another, in 2024, was the deliberation on the formation of the BRICS Cross-Border Payments Initiative (also known as BRICS Pay), where BRICS countries would trade with each other without converting to US dollars by utilising blockchain technology and tokens to circumvent the SWIFT financial payment system. Although BRICS Pay is still only a concept, its development would seriously undermine the US dollar’s long-standing dominance. Today, the inter-governmental organisation boasts of 10 full members with the inclusion of Egypt, Ethiopia, Iran, and the United Arab Emirates in January 2024, and Indonesia in January 2025; and has nine official partner countries—Nigeria is the ninth partner country of BRICS (admitted on 17 January 2025), joining Belarus, Bolivia, Cuba, Kazakhstan, Malaysia, Thailand, Uganda, and Uzbekistan. Statistically put, BRICS member countries comprise about 45 percent of the world’s population, 28 percent of the global economy, and collectively they produce more than a third of the world’s crude oil. And if Saudi Arabia joins the group (which it is yet to consider the BRICS invitation), the grouping would then produce some 43 percent of global crude oil. This growth among emerging nations is set to widen the gap between BRICS+ and the G7 nations. As IMF estimates suggest, BRICS+ will account for 37.6 percent of world GDP at purchasing power parity in 2027, compared with 28.2 percent for the G7. This will signify a shift in economic power towards emerging economies, enhance intra-BRICS trade and regional networks rather than relying on G7 markets, and also lead to the creation of alternate alliances and institutions. Apart from expanding its membership, BRICS has also broadened its agenda beyond economics to include global challenges. The two main pillars of BRICS are practical cooperation in various fields through meetings of Working Groups and Senior Officials, and consultation on matters of shared interests through meetings of Leaders and Ministers of Finance, Trade, Health, Science & Technology, Education, Agriculture, Communication, and Labour, among others. The intra-BRICS collaboration now includes social welfare, intellectual property, tourism, science & technology, culture, outer space, think tanks, and internet governance and security. With BRICS+, emerging economies are establishing new standards for order making. In other words, despite its informal existence, BRICS has emerged as a strong contestant for building an alternative discourse on global governance—one that is non-western. The expansion gives BRICS a greater economic and demographic weight as well as a stronger voice to the Global South, potentially reshaping discussions in institutions like the UN and WTO. However, the long-term success of an expanded BRICS will depend on its ability to balance diverse interests and act as a unified voice on the global stage. This article was published under a Creative Commons Licence.

International efforts, such as the Paris Agreement, aim to reduce greenhouse gas emissions. But experts say countries aren’t doing enough to limit dangerous global warming. Summary Countries have debated how to combat climate change since the early 1990s. These negotiations have produced several important accords, including the Kyoto Protocol and the Paris Agreement. Governments generally agree on the science behind climate change but have diverged on who is most responsible, how to track emissions-reduction goals, and whether to compensate harder-hit countries. The findings of the first global stocktake, discussed at the 2023 UN Climate Summit in Dubai, United Arab Emirates (UAE), concluded that governments need to do more to prevent the global average temperature from rising by 1.5°C. Introduction Over the last several decades, governments have collectively pledged to slow global warming. But despite intensified diplomacy, the world is already facing the consequences of climate change, and they are expected to get worse. Through the Kyoto Protocol and Paris Agreement, countries agreed to reduce greenhouse gas emissions, but the amount of carbon dioxide in the atmosphere keeps rising, heating the Earth at an alarming rate. Scientists warn that if this warming continues unabated, it could bring environmental catastrophe to much of the world, including staggering sea-level rise, devastating wildfires, record-breaking droughts and floods, and widespread species loss. Since negotiating the Paris accord in 2015, many of the 195 countries that are party to the agreement have strengthened their climate commitments—to include pledges on curbing emissions and supporting countries in adapting to the effects of extreme weather—during the annual UN climate conferences known as the Conference of the Parties (COP). While experts note that clear progress has been made towards the clean energy transition, cutting current emissions has proven challenging for the world’s top emitters. The United States, for instance, could be poised to ramp up fossil fuel production linked to global warming under the Donald Trump administration, which has previously minimized the effects of climate change and has withdrawn twice from the Paris Agreement. What are the most important international agreements on climate change? Montreal Protocol, 1987. Though not intended to tackle climate change, the Montreal Protocol [PDF] was a historic environmental accord that became a model for future diplomacy on the issue. Every country in the world eventually ratified the treaty, which required them to stop producing substances that damage the ozone layer, such as chlorofluorocarbons (CFCs). The protocol has succeeded in eliminating nearly 99 percent of these ozone-depleting substances. In 2016, parties agreed via the Kigali Amendment to also reduce their production of hydrofluorocarbons (HFCs), powerful greenhouse gases that contribute to climate change. UN Framework Convention on Climate Change (UNFCCC), 1992. Ratified by 197 countries, including the United States, the landmark accord [PDF] was the first global treaty to explicitly address climate change. It established an annual forum, known as the Conference of the Parties, or COP, for international discussions aimed at stabilizing the concentration of greenhouse gases in the atmosphere. These meetings produced the Kyoto Protocol and the Paris Agreement. Kyoto Protocol, 2005. The Kyoto Protocol [PDF], adopted in 1997 and entered into force in 2005, was the first legally binding climate treaty. It required developed countries to reduce emissions by an average of 5 percent below 1990 levels, and established a system to monitor countries’ progress. But the treaty did not compel developing countries, including major carbon emitters China and India, to take action. The United States signed the agreement in 1998 but never ratified it and later withdrew its signature.  Paris Agreement, 2015. The most significant global climate agreement to date, the Paris Agreement requires all countries to set emissions-reduction pledges. Governments set targets, known as nationally determined contributions (NDCs), with the goals of preventing the global average temperature from rising 2°C (3.6°F) above preindustrial levels and pursuing efforts to keep it below 1.5°C (2.7°F). It also aims to reach global net-zero emissions, where the amount of greenhouse gases emitted equals the amount removed from the atmosphere, in the second half of the century. (This is also known as being climate neutral or carbon neutral.) The United States, the world’s second-largest emitter, is the only country to withdraw from the agreement, a move President Donald Trump made during his first administration in 2017. While former President Joe Biden reentered the agreement during his first day in office, Trump again withdrew the United States on the first day of his second administration in 2025. Three other countries have not formally approved the agreement: Iran, Libya, and Yemen. Is there a consensus on the science of climate change? Yes, there is a broad consensus among the scientific community, though some deny that climate change is a problem, including politicians in the United States. When negotiating teams meet for international climate talks, there is “less skepticism about the science and more disagreement about how to set priorities,” says David Victor, an international relations professor at the University of California, San Diego. The basic science is that:• the Earth’s average temperature is rising at an unprecedented rate; • human activities, namely the use of fossil fuels—coal, oil, and natural gas—are the primary drivers of this rapid warming and climate change; and,• continued warming is expected to have harmful effects worldwide. Data taken from ice cores shows that the Earth’s average temperature is rising more now than it has in eight hundred thousand years. Scientists say this is largely a result of human activities over the last 150 years, such as burning fossil fuels and deforestation. These activities have dramatically increased the amount of heat-trapping greenhouse gases, primarily carbon dioxide, in the atmosphere, causing the planet to warm. The Intergovernmental Panel on Climate Change (IPCC), a UN body established in 1988, regularly assesses the latest climate science and produces consensus-based reports for countries. Why are countries aiming to keep global temperature rise below 1.5°C? Scientists have warned for years of catastrophic environmental consequences if global temperature continues to rise at the current pace. The Earth’s average temperature has already increased approximately 1.1°C above preindustrial levels, according to a 2023 assessment by the IPCC. The report, drafted by more than two hundred scientists from over sixty countries, predicts that the world will reach or exceed 1.5°C of warming within the next two decades even if nations drastically cut emissions immediately. (Several estimates report that global warming already surpassed that threshold in 2024.) An earlier, more comprehensive IPCC report summarized the severe effects expected to occur when the global temperature warms by 1.5°C: Heat waves. Many regions will suffer more hot days, with about 14 percent of people worldwide being exposed to periods of severe heat at least once every five years. Droughts and floods. Regions will be more susceptible to droughts and floods, making farming more difficult, lowering crop yields, and causing food shortages.  Rising seas. Tens of millions of people live in coastal regions that will be submerged in the coming decades. Small island nations are particularly vulnerable. Ocean changes. Up to 90 percent of coral reefs will be wiped out, and oceans will become more acidic. The world’s fisheries will become far less productive. Arctic ice thaws. At least once a century, the Arctic will experience a summer with no sea ice, which has not happened in at least two thousand years. Forty percent of the Arctic’s permafrost will thaw by the end of the century.  Species loss. More insects, plants, and vertebrates will be at risk of extinction.  The consequences will be far worse if the 2°C threshold is reached, scientists say. “We’re headed toward disaster if we can’t get our warming in check and we need to do this very quickly,” says Alice C. Hill, CFR senior fellow for energy and the environment. Which countries are responsible for climate change? The answer depends on who you ask and how you measure emissions. Ever since the first climate talks in the 1990s, officials have debated which countries—developed or developing—are more to blame for climate change and should therefore curb their emissions. Developing countries argue that developed countries have emitted more greenhouse gases over time. They say these developed countries should now carry more of the burden because they were able to grow their economies without restraint. Indeed, the United States has emitted the most of all time, followed by the European Union (EU).   However, China and India are now among the world’s top annual emitters, along with the United States. Developed countries have argued that those countries must do more now to address climate change.   In the context of this debate, major climate agreements have evolved in how they pursue emissions reductions. The Kyoto Protocol required only developed countries to reduce emissions, while the Paris Agreement recognized that climate change is a shared problem and called on all countries to set emissions targets. What progress have countries made since the Paris Agreement? Every five years, countries are supposed to assess their progress toward implementing the agreement through a process known as the global stocktake. The first of these reports, released in September 2023, warned governments that “the world is not on track to meet the long-term goals of the Paris Agreement.” That said, countries have made some breakthroughs during the annual UN climate summits, such as the landmark commitment to establish the Loss and Damage Fund at COP27 in Sharm el-Sheikh, Egypt. The fund aims to address the inequality of climate change by providing financial assistance to poorer countries, which are often least responsible for global emissions yet most vulnerable to climate disasters. At COP28, countries decided that the fund will be initially housed at the World Bank, with several wealthy countries, such as the United States, Japan, the United Kingdom, and EU members, initially pledging around $430 million combined. At COP29, developed countries committed to triple their finance commitments to developing countries, totalling $300 billion annually by 2035. Recently, there have been global efforts to cut methane emissions, which account for more than half of human-made warming today because of their higher potency and heat trapping ability within the first few decades of release. The United States and EU introduced a Global Methane Pledge at COP26, which aims to slash 30 percent of methane emissions levels between 2020 and 2030. At COP28, oil companies announced they would cut their methane emissions from wells and drilling by more than 80 percent by the end of the decade. However, pledges to phase out fossil fuels were not renewed the following year at COP29. Are the commitments made under the Paris Agreement enough? Most experts say that countries’ pledges are not ambitious enough and will not be enacted quickly enough to limit global temperature rise to 1.5°C. The policies of Paris signatories as of late 2022 could result in a 2.7°C (4.9°F) rise by 2100, according to the Climate Action Tracker compiled by Germany-based nonprofits Climate Analytics and the NewClimate Institute. “The Paris Agreement is not enough. Even at the time of negotiation, it was recognized as not being enough,” says CFR’s Hill. “It was only a first step, and the expectation was that as time went on, countries would return with greater ambition to cut their emissions.” Since 2015, dozens of countries—including the top emitters—have submitted stronger pledges. For example, President Biden announced in 2021 that the United States will aim to cut emissions by 50 to 52 percent compared to 2005 levels by 2030, doubling former President Barack Obama’s commitment. The following year, the U.S. Congress approved legislation that could get the country close to reaching that goal. Meanwhile, the EU pledged to reduce emissions by at least 55 percent compared to 1990 levels by 2030, and China said it aims to reach peak emissions before 2030. But the world’s average temperature will still rise more than 2°C (3.6°F) by 2100 even if countries fully implement their pledges for 2030 and beyond. If the more than one hundred countries that have set or are considering net-zero targets follow through, warming could be limited to 1.8˚C (3.2°F), according to the Climate Action Tracker.   What are the alternatives to the Paris Agreement? Some experts foresee the most meaningful climate action happening in other forums. Yale University economist William Nordhaus says that purely voluntary international accords like the Paris Agreement promote free-riding and are destined to fail. The best way to cut global emissions, he says, would be to have governments negotiate a universal carbon price rather than focus on country emissions limits. Others propose new agreements [PDF] that apply to specific emissions or sectors to complement the Paris Agreement.  In recent years, climate diplomacy has occurred increasingly through minilateral groupings. The Group of Twenty (G20), representing countries that are responsible for 80 percent of the world’s greenhouse gas pollution, has pledged to stop financing new coal-fired power plants abroad and agreed to triple renewable energy capacity by the end of this decade. However, G20 governments have thus far failed to set a deadline to phase out fossil fuels. In 2022, countries in the International Civil Aviation Organization set a goal of achieving net-zero emissions for commercial aviation by 2050. Meanwhile, cities around the world have made their own pledges. In the United States, more than six hundred local governments [PDF] have detailed climate action plans that include emissions-reduction targets. Industry is also a large source of carbon pollution, and many firms have said they will try to reduce their emissions or become carbon neutral or carbon negative, meaning they would remove more carbon from the atmosphere than they release. The Science Based Targets initiative, a UK-based company considered the “gold standard” in validating corporate net-zero plans, says it has certified the plans of  over three thousand firms, and aims to more than triple this total by 2025. Still, analysts say that many challenges remain, including questions over the accounting methods and a lack of transparency in supply chains. Recommended Resources This timeline tracks UN climate talks since 1992. CFR Education’s latest resources explain everything to know about climate change.  The Climate Action Tracker assesses countries’ updated NDCs under the Paris Agreement. CFR Senior Fellow Varun Sivaram discusses how the 2025 U.S. wildfires demonstrate the need to rethink climate diplomacy and adopt a pragmatic response to falling short of global climate goals. In this series on climate change and instability by the Center for Preventive Action, CFR Senior Fellow Michelle Gavin looks at the consequences for the Horn of Africa and the National Defense University’s Paul J.

Abstract Climate change is considered to be one of the biggest problems acknowledged globally today. Therefore, the causes of climate change and solutions to this problem are frequently investigated. For this reason, the purpose of this study is to empirically examine whether the ‘Climate Change Performance Index’ (CCPI) is successful in increasing environmental investments for E-7 countries with the data for the period of 2008–2023. To achieve this aim, the Parks-Kmenta estimator was used as the econometric method in the study. The study findings provide strong evidence that increases in the climate change performance support environmental investments. High climate change performance directs governments and investors toward investing in this area; therefore, environmental investments tend to increase. The study also examined the effects of population growth, real GDP and inflation on environmental investments. Accordingly, it has been concluded that population growth and inflation negatively affect environmental investments, while GDP positively affects environmental investments. 1. Introduction There is a broad consensus that the main cause of climate change is human-based greenhouse gas emissions from non-renewable (i.e., fossil) fuels and improper land use. Accordingly, climate change may have serious negative consequences as well as significant macroeconomic outcomes. For example, an upward trend of temperatures, the rising sea levels, and extreme weather conditions can seriously disrupt the output and productivity (IMF, 2008a; Eyraud et al., 2013). Due to the global climate change, many countries today see environmental investments, especially renewable energy investments, as an important part of their growth strategies. Until recent years, the most important priority of many countries was an improvement in the economic growth figures. Still, the global climate change and the emergence of many related problems are now directing countries toward implementing policies which would be more sensitive to the environment and would ensure sustainable growth rather than just increase the growth figures. (Baştürk, 2024: 327). The orientation of various countries to these policies has led to an increase in environmental investments on a global scale. A relative rise of the share of environmental investments worldwide is not only a medium-term climate goal. It also brings many new concepts to the agenda, such as an increasing energy security, reduction of the negative impact of air pollution on health, and the possibility of finding new growth resources (Accenture, 2011; McKinsey, 2009; (OECD), 2011; PriceWaterhouseCoopers, 2008; Eyraud et al., 2013). Today, environmental investments have a significant share in energy and electricity production. According to the World Energy Outlook (2023), investments in environmentally friendly energies have increased by approximately 40% since 2020. The effort to reduce emissions is the key reason for this increase, but it is not the only reason. Economic reasons are also quite strong in preferring environmental energy technologies. For example, energy security is also fundamentally important in the increase in environmental investments. Especially in fuel-importing countries, industrial plans and the necessity to spread clean (i.e., renewable) energy jobs throughout the country are important factors (IEA WEO, 2023).  In economic literature, environmental investments are generally represented by renewable energy investments. Accordingly, Figure 1 below presents global renewable energy electricity production for 2000–2020. According to the data obtained from IRENA (2024) and Figure 1, the total electricity production has increased by approximately 2.4% since 2011, with renewable energy sources contributing 6.1% to this rate, while non-renewable energy sources contributed 1.3%. In 2022 alone, renewable electricity grew by 7.2% compared to 2021. Solar and wind energy provided the largest growth in renewable electricity since 2010, which reached 11.7% of the global electricity mix in 2022.   Figure 2 below presents renewable energy investments by technology between 2013 and 2022. As shown in Figure 2, photovoltaic solar. and terrestrial wind categories are dominating, accounting for 46% and 32% of the global renewable energy investment, respectively, during 2013–2022.   Economic growth supported by environmental investments is impacted by the type and number of energy used to increase the national output. Thus, both the environmental friendliness of the energy used and the rise in energy efficiency is bound to reduce carbon emissions related to energy use and encourage economic growth (Hussain and Dogan, 2021). In this context, in order to minimize emissions and ensure sustainable economic growth, renewable energy sources should be used instead of fossil resources in energy use. Increasing environmental investments on a global scale, especially a boost in renewable energy investments, is seen as a more comprehensive solution to the current global growth-development and environmental degradation balance. In this context, as a result of the latest Conference of the Parties held in Paris, namely, COP21, it was envisaged to make an agreement covering the processes after 2020, which is accepted as the end year of the Kyoto Protocol. On December 12, 2015, the Paris Agreement was adopted unanimously by the countries that are parties to the UN Framework Convention on Climate Change (Kaya, 2020). As a result of the Paris Agreement and the reports delivered by the Intergovernmental Climate Change Panels, international efforts to adapt to the action to combat climate change and global warming have increased, and awareness has been raised in this area (Irfan et al., 2021; Feng et al., 2022; Anser et al., 2020; Zhang et al., 2021; Huang et al., 2021; Fang, 2023). The rise in the demand for low-carbon energy sources in economies has been caused by environmental investments such as renewable energy investments. The countries that are party to the Paris Agreement, commit to the way to achieve efficient energy systems through the spread of renewable energy technologies throughout the country (Bashir et al., 2021; Fang, 2023). This study empirically examines the impact of the climate change performance on increasing environmental investments for E-7 countries. The climate change performance is expressed by the ‘Climate Change Performance Index’ (CCPI) developed by the German environmental and developmental organization Germanwatch. The index evaluates the climate protection performance of 63 developed and developing countries and the EU annually, and compares the data. Within this framework, CCPI seeks to increase clarity in international climate policies and practices, and enables a comparison of the progress achieved by various countries in their climate protection struggle. CCPI evaluates the performance of each country in four main categories: GHG Emissions (40% overall ranking), Renewable Energy (20%), Energy Use (20%), and Climate Policy (20%). In calculating this index, each category of GHG emissions, renewable energy, and energy use is measured by using four indicators. These are the Current Level, the Past Trend, the Current Level Well Below 2°C Compliance, and the Countries’ Well Below 2°C Compliance with the 2030 Target. The climate policy category is evaluated annually with a comprehensive survey in two ways: as the National Climate Policy and the International Climate Policy (https://ccpi.org/methodology/).  Figure 3 below shows the world map presenting the total results of the countries evaluated in CCPI 2025 and their overall performance, including the four main categories outlined above.   As it can be seen from Figure 3, no country appears strong enough to receive a ‘very high’ score across all categories. Moreover, although Denmark continues to be the highest-ranking country in the index, but it still does not perform well enough to receive a ‘very high’ score overall. On the other hand, India, Germany, the EU, and the G20 countries/regions will be among the highest-performing countries/regions in the 2024 index. When we look at Canada, South Korea, and Saudi Arabia, they are the worst-performing countries in the G20. On the other hand, it can be said that Türkiye, Poland, the USA, and Japan are the worst-performing countries in the overall ranking. The climate change performance index is an important criterion because it indicates whether the change and progress in combating climate change is occurring across all countries at an important level. The index is important in answering various questions for countries under discussion. These questions are expressed below:  • In which stage are the countries in the categories in which the index is calculated?• What policies should countries follow after seeing the stages in which they are in each category? • Which countries are setting an example by truly combating climate change? These questions also constitute the motivation for this study. The sample group for the study was selected as E-7 countries, which are called the Emerging Economies; this list consists of Türkiye, China, India, Russia, Brazil, Mexico, and Indonesia. The reason for selecting these particular countries is that they are undergoing a rapid development and transformation process, and are also believed to be influential in the future with their increasing share in the world trade volume, huge populations, and advances in technology. Besides that, when the relevant literature has been examined, studies that empirically address the relative ranking of the climate change performance appear to be quite limited. In particular, there are almost no studies evaluating the climate change performance index for the sample group considered. Therefore, it is thought that this study will be of great importance in filling this gap in the literature. The following section of the study, which aims to empirically examine whether the climate change performance is effective in developing environmental investments in E-7 countries, includes national and international selected literature review on the subject. Then, the model of the study and the variables chosen in this model are introduced. Then, the findings obtained in the study are shared, and the study ends with discussion and policy proposal. 2. Literature Review 2.1. Studies on environmental investment  The excessive use of fossil-based energy sources, considered non-renewable and dirty energy, along with industrialization, constitutes a large part of carbon emissions and is regarded as the main reason of climate change. Thus, countries have turned to renewable energy investments with the objective to minimize the reaction of climate change and global warming, by introducing technologies which are considered more environmentally friendly and cleaner. Global energy investments are estimated to exceed 3 trillion US dollars by the end of 2024, and 2 trillion US dollars of this amount will go to clean and environmentally friendly energy base technologies and infrastructure. Investment in environmentally friendly energy has been gaining speed since 2020, and the total expense on renewable energy, networks, and storage now represents a higher figure than the total spending on oil, gas, and coal (IEA, 2024). When the energy economics literature is examined, since environmental investments are mostly represented by renewable energy investments, renewable energy investments studies and studies in related fields shall be discussed in this study section. One of the important studies in this field is the work of Eyraud et al. (2013). In the study, the authors analyzed the determinants of environmental and green (clean) investments for 35 developed and developing countries. Accordingly, they stated in the study that environmental investment has become the main driving force of the energy sector, and China has generally driven its rapid growth in recent years. In addition, in terms of the econometric results of the study, it has been found that environmental investments are supported by economic growth, a solid financial system suitable for lower interest rates, and higher fuel prices. Fang (2023) examined the relationship between investments in the renewable energy sector, the economic complexity index, green technological innovation, industrial structure growth, and carbon emissions in 32 provinces in China for the period of 2005–2019 by using the GMM method. Based on the study results, the economic complexity index causes an increase in China’s carbon dioxide levels. On the contrary, all of the following – the square of the economic complexity index, investments in clean energy, green technical innovation, and the industrial structure – were found to help decrease carbon dioxide emissions. Another important study in this field is the work of Masini and Menichetti (2013). The authors examined the non-financial sources of renewable energy investments in their study. Accordingly, the study results show that knowledge and confidence in technological competence positively impact renewable energy investments. In addition, trust in policy measures only impacts PV (Photovoltaic) and hydropower investments, whereas institutional pressure negatively impacts renewable energy investments. Finally, the study stated that experienced investors are more likely to fund innovations in renewable energy. One of the important studies on renewable energy investments is the work of Ozorhon et al. (2018). To support and facilitate the decision-making process in renewable energy investments, the authors determined the main criteria affecting investors’ decisions by reviewing the literature and examining sector-level practices. According to the findings, economic criteria, like policies and regulations, funds availability, and investment costs were the most important factors in the decision-making process for renewable energy investments. Xu et al. (2024) examined the relationship between the renewable energy investments and the renewable energy development with a threshold value analysis for China. According to the results, impact of the clean (renewable) energy investment on renewable energy development has a significant threshold value, and the general relation between them is a ‘V’ type non-linear relation. At this point, the study suggests that the state should keep spending in the segment of investments in clean energy, increase the financial proficiency, and ensure an efficient financial infrastructure for clean energy in China. 2.2. Studies on Climate Change and their Impact on Economic Variables  The widespread use of fossil-based energy sources, considered dirty energy, continues to create a negative externality in carbon emissions despite the globally implemented policies like the Kyoto Protocol and the Paris Agreement (Rezai et al., 2021). The economic literature on climate change focuses particularly on the adverse effect of climate change on the economy. One of the important studies in this field is the study of Fan et al. (2019). In their study, the authors focused on the impact of climate change on the energy sector for 30 provinces in China and conducted their research with the help of a fixed-effect regression feedback model. As a result of the study, it was found that hot and low-temperature days positively affected the electricity demand. On the other hand, Singh et al. (2022) examined the effects of climate change on agricultural sustainability in India with data from 1990–2017. On the grounds of the study, it was found that India’s agricultural sector was negatively impacted by the climate change. In this regard, it is stated that India needs to take powerful climate policy action so that to reduce the adverse effect of the climate change and increase its sustainable agricultural development. One of the important studies in this field is the study of Gallego-Alvarez et al. (2013). This study investigated how the climate change affects the financial performance with a sample of 855 international companies operating in sectors with high greenhouse gas/ CO2 emissions from 2006–2009. The results reveal that the relationship between the environmental and financial performance is higher in times of economic crisis triggered by climate crisis. In other words, these results show that companies should continue investing in sustainable projects in order to achieve higher profits. Kahn et al. (2021) examined the long-term macroeconomic impact of the climate change by using a panel data set consisting of 174 countries between 1960 and 2014. According to the findings, the amount of output per capita is negatively affected by temperature changes, but no statistically significant effect is observed for changes in precipitation. In addition, according to the study’s results, the main effects of temperature shocks also vary across income groups. Alagidede et al. (2015) examined the effect of climate change on sustainable economic growth in the Sub-Saharan Africa region in their study. The study stated that the relationship between the real GDP and the climate change is not linear. In addition, Milliner and Dietz (2011) investigated the long-term economic consequences of the climate change. Accordingly, as the economy develops over time, and as progress is achieved, this situation will automatically be less affected by the adverse impact of the climate change. Structural changes made with economic development will make sectors more sensitive to the climate change, such as the agricultural sector, which would become stronger and less dependent. Dell et al. (2008) examined the effect of climate change on economic activity. The study’s main results are as follows: an increase of temperatures significantly decreases economic growth in low-income countries. Furthermore, increasing temperature does not affect economic growth in high-income countries. On the other hand, when examining the effects of climate change on the economy, the study of Zhou et al. (2023) is also fundamentally important. Zhou et al. (2023) examined the literature on the effects of climate change risks on the financial sector. In the studies examined, it is generally understood that natural disasters and climate change reduce bank stability, credit supply, stock and bond market returns, and foreign direct investment inflows. In their study for Sri Lanka, Abeysekara et al. (2023) created a study using the general equilibrium model ORANI-G-SL with the objective to investigate the economic impacts of the climate change on agricultural production. The study findings suggest that reductions in the production of many agricultural products will lead to increases in consumer prices for these agricultural commodities, resulting in a decrease in the overall household consumption. The projected decrease in crop production and increases in food prices will increase the potential for food insecurity Another important document in this field is the study by Caruso et al. (2024) examining the relationship between the climate change and human capital. The study findings reveal a two-way result regarding the effects of the climate change damages and the effects of climate change mitigation and adaptation on the human capital. Accordingly, the climate change has direct effects on health, nutrition and welfare, while changes in markets and damage to the infrastructure are expressed as indirect effects. In addition to these studies, the uncertainty of the climate change policies also exerts an impact on economic factors. Studies conducted in this context in recent years have also enriched the literature on the climate change. For example, Çelik and Özarslan Doğan (2024) examined the effects of uncertainty of the climate change policies on economic growth for the USA by using the ARDL bounds test. Their results confirmed the existence of a positive and statistically significant relationship between the climate policy uncertainty and economic growth in the USA. 3. Model Specification  This study empirically examines whether the climate change performance index successfully develops environmental investments in E-7 countries. For further details related to the mathematical model check https://doi.org/10.15388/Ekon.2025.104.2.6 4. Conclusion and Policy Implications  Today, many national and international initiatives are within the scope of combating global warming and climate change. In addition, many developed and developing countries are differentiating their growth and development policies with the objective to prevent these disasters. Although they vary from country to country, as well as from region to region, these policies mostly represent those policies which reduce carbon emissions and ensure energy efficiency. At this point, the key factor is renewable energy investments, which represent environmentally friendly investments. However, according to Abban and Hasan (2021), the amount of environmentally friendly investments is not the same in every country. This is because the determinants of environmentally friendly investments vary from country to country. While financial and economic factors are more encouraging in increasing these investments in some countries, international sanctions are the driving force in this regard in some other countries as well. This study aims to empirically examine whether CCPI is effective in the success of environmental investments in the E-7 countries in the period of 2008–2023 with the help of the Parks-Kmenta estimator. In this direction, the study’s dependent variable is environmental investments, represented by renewable energy investments. On the other hand, the climate change performance is represented by the ‘Climate Change Performance Index’ calculated by Germanwatch, which constitutes the main independent variable of the study. Other control variables considered in the study are the population growth, the real GDP per capita, and inflation. The study findings provide strong evidence that increases in the climate change performance support environmental investments. High-rate climate change performance drives governments and investors toward investing in this area; thus, environmental investments tend to increase. These results are consistent with the study results of Raza et al. (2021). As a result of their study, Raza et al. (2021) stated that the climate change performance is an important channel for the general environmental change, and that renewable energy has a very important role in this regard.  In addition, the study concludes that population growth and inflation negatively affect environmental investments. These results are consistent with Suhrab et al. (2023), but not with Yang et al. (2016). While Suhrab et al. (2023) obtained results regarding the negative effects of inflation on green investments, Yang et al. (2016) focused on the positive effect of population on renewable energy. Finally, the effect of the real GDP per capita on environmental investments has been found to be positive. These results are also consistent with Tudor and Sova (2021). The authors found that Real GDP encourages green investments. This study offers policymakers a number of policy recommendations. These are presented below. • One of the important factors affecting the climate change performance is the raising of awareness of the populations in these countries at this point, and providing them with the knowledge to demand clean energy. In this way, consumers, would demand environmental energy, and investors would invest more in this area. This is of great importance in increasing environmental investments. • The climate change performance also shows how transparent the energy policies implemented by countries are. Therefore, the more achievable and explanatory are the goals of policy makers in this regard, the more climate change performance will increase, which will strengthen environmental investments. • Moreover, the initial installation costs are the most important obstacles on the way toward developing environmental investments. At this point, the country needs to develop support mechanisms that would encourage investors to invest more. • Environmental investments, similar to other types of physical investments, are greatly affected by the country’s macroeconomic indicators. At this point, a stable and foresighted economic policy will encourage an increase in such investments. The countries in the sample group represent developing countries. Therefore, in many countries in this category, the savings rates within the country are insufficient to make investments. At this point, the financial system that will bring together those who supply funds and those who demand funds in the country; this system needs to be developed further. In addition, more extensive use of new and various financial instruments should be encouraged with the objective to collect the capital required for environmental investments. References Abban, A.

Nuclear power capacity is expected to double, escalating from 413 gigawatts (GW) in early 2022 to 812 GW by 2050 within the net zero emissions (NZE) paradigm. The global energy landscape is undergoing significant transformation as nations strive to transition to more sustainable energy systems. Amidst this shift, nuclear power has emerged as a crucial component in the pursuit of a sustainable energy transition. This study examines nuclear power's multifaceted role in shaping sustainable energy transition. It delves into nuclear energy's contributions toward decarbonization efforts, highlighting its capacity to provide low-carbon electricity and its potential role in mitigating climate change. Furthermore, the study explores the challenges and opportunities associated with integrating nuclear power into energy transition strategies, addressing issues such as safety, waste management, and public perception. In conclusion, the global nuclear power capacity is anticipated to reach approximately 530 GW by 2050, representing a substantial shortfall of 35% compared with the trajectory outlined in the NZE pathway. Under the NZE scenario, nuclear power demonstrates exceptional expansion, nearly doubling from 413 GW in early 2022 to 812 GW by 2050. Concurrently, the trajectory highlights a transformative shift in renewable energy investments, with annual expenditures surging from an average of US$325 billion during 2016–2020 to an impressive US$1.3 trillion between 2031 and 2035. These projections underscore the critical role of nuclear and renewable energy investments in achieving global sustainability and emission reduction goals. Introduction Global warming and greenhouse gas emissions pose some of the most pressing challenges of the 21st century. The combustion of fossil fuels for electricity generation is a major contributor to these issues, releasing billions of tons of carbon dioxide (CO2) into the atmosphere annually (Abbasi et al., 2020; Nassar et al., 2024; Rekik and El Alimi, 2024a). In this context, nuclear energy emerges as a critical component of the solution. Unlike fossil fuels, nuclear power generates electricity with minimal greenhouse gas emissions, offering a reliable and scalable alternative to bridge the gap between energy demand and decarbonization goals. It operates independently of weather conditions, providing consistent energy output and complementing the intermittency of renewable sources like wind and solar (Rekik and El Alimi, 2024b, 2024c). Furthermore, advancements in nuclear technologies, including small modular reactors (SMRs) and generation IV reactors, have addressed historical concerns related to safety, waste management, and cost-effectiveness (Lau and Tsai, 2023). In 2022, global investment in low-emission fuels will maintain a robust growth trajectory, reaching a sum of US$13 billion. A significant portion of this investment was allocated toward liquid biofuels, totaling US$9.4 billion, and biogas, amounting to US$2.7 billion. It is important to emphasize that liquid biofuels constituted approximately 80% of the overall investment surge observed in 2022, with investments in biogas contributing 4% of the total. The residual portion of the investment was directed toward low-emission hydrogen production, which attained a sum of US$1.2 billion in 2022, representing an almost fourfold increase compared to the figures recorded in 2021 (Khaleel et al., 2024).Nuclear power is a pivotal component of low-carbon energy, which significantly contributes to the realization of a low-carbon economy and establishment of a green energy grid (Arvanitidis et al., 2023; El Hafdaoui et al., 2024; Fragkos et al., 2021). According to current data, 442 nuclear power reactors are operational worldwide, collectively generating 393 gigawatts (GW) of electricity, thereby furnishing a consistent and dependable source of low-carbon power (Mathew, 2022). Nuclear electricity constitutes approximately 11% of the total global electricity generation, representing a substantial portion of the global low-carbon electricity production (Alam et al., 2019). Recent advancements have enhanced the affordability and appeal of nuclear power as an alternative source of energy. These advancements encompass progress in large reactor technologies, the emergence of novel approaches such as advanced fuel utilization and SMRs, engineering breakthroughs facilitating the extension of operational lifespans for existing reactors, and innovations in materials science and improved waste management practices (Kröger et al., 2020; Zhan et al., 2021). Fast breeder reactor technology has transitioned into a commercial realm, offering benefits beyond electricity generation by enabling the production of surplus fuel and enhancing the efficiency of nuclear waste incineration, surpassing the capabilities of existing commercial reactor technologies (Lau and Tsai, 2023). Nuclear power plays a substantial role within a secure global trajectory toward achieving net zero emissions (NZE) (Addo et al., 2023; Dafnomilis et al., 2023). Nuclear power capacity experiences a twofold increase, progressing from 413 GW at the outset of 2022 to 812 GW by 2050 within the NZE paradigm. It is apparent that the annual additions to nuclear capacity peaked at 27 GW per year during the 2030s, surpassing the levels observed in the preceding decade. Despite these advancements, the global proportion of nuclear power within the overall electricity generation portfolio has experienced a marginal decline, settling at 8% (Murphy et al., 2023; Ruhnau et al., 2023). Emerging and developing economies (EMDEs) substantially dominate global growth, constituting over 90% of the aggregate, with China poised to ascend as a preeminent nuclear power producer prior to 2030. Concurrently, advanced economies collectively witness a 10% augmentation in nuclear power capacity as retirements are counterbalanced by the commissioning of new facilities, predominantly observed in nations such as the United States, France, the United Kingdom, and Canada (Bórawski et al., 2024). Furthermore, annual global investment in nuclear power has experienced a notable escalation, soaring from US$30 billion throughout the 2010s to surpass US$100 billion by 2030, maintaining a robust trajectory above US$80 billion by 2050 (IEA, 2022). In 2022, global nuclear power capacity experienced a modest increase of approximately 1.5 GW, reflecting a marginal year-on-year growth of 0.3%. This expansion was primarily driven by new capacity additions that surpassed the retirement of an over 6 GW of existing capacity (Fernández-Arias et al., 2023; Mendelevitch et al., 2018). EMDEs accounted for approximately 60% of the new capacity additions, underscoring their increasing significance in the global nuclear energy landscape. Conversely, more than half of the retirements were observed in advanced economies, including Belgium, the United Kingdom, and the United States. Table 1 shows the nuclear power capacity by region in the NZE from 2018 to 2030.   In alignment with the Net Zero Scenario, it is imperative for the global nuclear capacity to undergo an expansion averaging approximately 15 GW per annum, constituting a growth rate slightly exceeding 3% annually, until 2030. This strategic augmentation is crucial for sustaining the contribution of the nuclear sector to electricity generation, maintaining its share at approximately 10% (Liu et al., 2023). Such an expansion necessitates concerted efforts in both advanced economies and EMDEs. Furthermore, prioritizing the extension of operational lifetimes of existing nuclear facilities within G7 member states would not only fortify the existing low-emission infrastructure, but also facilitate the integration of new nuclear capacity, thereby augmenting the overall nuclear energy portfolio. [...] The significant contribution of nuclear power to sustainable energy transitions is underscored by its multifaceted role in addressing the pressing challenges of climate change and energy security (Asif et al., 2024). As nations worldwide endeavor to shift toward greener energy systems, nuclear power has emerged as a critical pillar of the decarbonization journey. Its ability to provide low-carbon electricity, mitigate climate change impacts by 2050, and enhance energy security highlights its pivotal importance in the broader context of sustainable energy transitions (Bhattacharyya et al., 2023; NEA, 2015). Thus, to fully realize its potential, challenges such as safety, waste management, and public perception must be addressed effectively. By leveraging robust policy frameworks, technological advancements, and international collaboration, nuclear power is poised to play a vital role in shaping the future of sustainable energy transitions on a global scale. Furthermore, the dynamic landscape of nuclear power development is evident in the significant influence exerted by EMDEs, particularly China, which is expected to emerge as a leading nuclear power producer by 2030 (Fälth et al., 2021; Nkosi and Dikgang, 2021). Concurrently, advanced economies are witnessing notable expansions in nuclear power capacity driven by the commissioning of new facilities to offset retirements (Budnitz et al., 2018). This trend is further reinforced by a notable surge in annual global investment in nuclear power, underscoring the sustained commitment to nuclear energy's pivotal role in sustainable energy transitions in the foreseeable future (IEA, 2019). The primary objective of this article is to explore the strategic role of nuclear power in advancing global sustainability goals and achieving zero emissions. The objective is structured around the following key agendas: •Nuclear power: prominence and green electricity source•Nuclear's role in achieving net zero by 2050•Nuclear power's significance in power system adequacySpecific technologies for sustainability in nuclear energy production•Investment in nuclear power•Addressing policy implications This comprehensive analysis aims to provide actionable insights into harnessing nuclear power for sustainable electricity generation and its pivotal role in achieving global zero-emission targets. Data and methodology This article conducts an in-depth analysis of the role of nuclear power in achieving sustainable electricity generation and supporting NZE targets. The article also addresses the potential of nuclear energy as a prominent and environmentally favorable electricity source, examining nuclear power's contribution toward the net zero by 2050 goal, its critical importance in ensuring power system adequacy, investment imperatives, and the broader policy implications.  [...] Nuclear power: prominence and green electricity source In 2020, nuclear power will constitute approximately 10% of the global electricity generation portfolio. This proportion, which had previously stood at 18% during the late 1990s, has experienced a decline; nonetheless, nuclear energy retains its status as the second-largest provider of low-emission electricity, trailing only hydroelectricity, and serves as the primary source within advanced economies. Despite the substantial proliferation of wind and solar PV technologies, nuclear electricity production in 2020 surpassed the aggregate output of these renewable sources. As of 2021, the global cumulative installed nuclear capacity has reached 413 GW, with 270 GW of this total being installed in advanced economies (Guidi et al., 2023; Halkos and Zisiadou, 2023; Pan et al., 2023; Zhang et al., 2022). Nuclear power generation during this period amounted to 2653 TWh, positioning it as the second largest source of electricity generation after hydropower, which generated 4275 TWh, as depicted in Figure 1.   In addition to its significant role in power generation, nuclear energy plays a crucial role in mitigating carbon dioxide (CO2) emissions. Since the 1970s, nuclear power has helped avoid the global release of approximately 66 gigatons (Gt) of CO2 globally, as shown in Figure 2.   Without the contribution of nuclear power, cumulative emissions from electricity generation would have increased by approximately 20%, whereas total energy-related emissions would have increased by 6% over this period (Wagner, 2021). Advanced economies accounted for more than 85% of these avoided emissions, with the European Union accounting for 20 Gt and the United States for 24 Gt, representing over 40% and 25% of total electricity generation emissions, respectively. In the absence of nuclear power, Japan would have experienced an estimated 25% increase in emissions from electricity generation, whereas Korea and Canada would have seen an increase of approximately 50%. Nuclear's role in achieving net zero by 2050 Nuclear energy has emerged as a pivotal low-emission technology within the trajectory toward achieving NZE (Pioro et al., 2019). In addition, it serves as a complementary force, bolstering the accelerated expansion of renewables, thereby facilitating the reduction of emissions from the global electricity sector to net zero by 2040 (Krūmiņš and Kļaviņš, 2023; Islam et al., 2024). Beyond its intrinsic contribution to fostering a low-emission electricity supply, nuclear power is significant as a dispatchable generating asset, fortifying supply security through its provision of system adequacy and flexibility. Furthermore, it is instrumental in furnishing heat for district heating networks and in selecting industrial facilities. Despite this, the prospective role of nuclear energy hinges significantly on the deliberations and determinations of policymakers and industry stakeholders concerning the pace of new reactor construction initiatives and the continued operational lifespan of existing nuclear facilities (Li et al., 2016; Li et al., 2015).In terms of the NZE trajectory, the global nuclear power capacity exhibits a remarkable surge, nearly doubling from 413 GW at the onset of 2022 to 812 GW by 2050 (Price et al., 2023; Utami et al., 2022). This augmentation primarily stems from the vigorous initiation of new construction endeavors, which effectively counterbalance the gradual decommissioning of numerous extant plants. Such an escalation constitutes a pronounced acceleration in comparison to the preceding three decades, characterized by a mere 15% increment in capacity, equivalent to approximately 60 GW (Haneklaus et al., 2023; Obekpa and Alola, 2023; Sadiq et al., 2023). Figure 3 demonstrates the nuclear power capacity within each country/region under the NZE by 2050 scenario.   The expected growth in nuclear power capacity far exceeds the path outlined by the current policies and legal frameworks. According to the Stated Policies Scenario (STEPS), the nuclear capacity is projected to reach approximately 530 GW by 2050, which is 35% lower than that of the NZE pathway (Espín et al., 2023; Nicolau et al., 2023; Nnabuife et al., 2023; Wang et al., 2023). Without a significant shift from recent nuclear power development trends, achieving NZE would require a limited reliance on a smaller range of low-emission technologies. This could compromise energy security and lead to higher total investment costs, resulting in increased electricity prices for consumers. Table 2 shows the average annual capacity addition for global nuclear power in NZE from 1981 to 2030.   In 2022, the global deployment of new nuclear power capacity witnessed a notable upsurge, with 7.9 GW added, representing a substantial 40% increase compared to the preceding year (Ho et al., 2019). It is worth bearing in mind that China spearheaded this expansion by completing the construction of two reactors, maintaining its streak for consecutive years as the leading contributor to global nuclear power capacity augmentation. It is noteworthy that the projects were successfully completed in various other nations, including Finland, Korea, Pakistan, and the United Arab Emirates. Additionally, significant strides were made in the initiation of new construction endeavors, with the commencement of construction activities on five reactors in China, two reactors in Egypt, and one reactor in Turkey (Hickey et al., 2021). Nuclear power's significance in power system adequacy Nuclear power facilities have persistently underpinned the dependability of power systems, thereby bolstering the adequacy of the system. Across diverse national contexts, nuclear power plants have historically maintained operational readiness, manifesting availability rates consistently exceeding 90%, thereby demonstrating their reliability in power generation. Given that a substantial proportion of nuclear power capacity directly contributes to system adequacy metrics, its significance in fortifying system reliability and adequacy significantly outweighs its proportional contribution to the total power capacity (Orikpete and Ewim, 2024; Frilingou et al., 2023; Raj, 2023; Ragosa et al., 2024). The contribution of nuclear power to system adequacy is demonstrated by the consistent trajectory of its share within the aggregate dispatchable power capacity, hovering at around 8% between 2021 and 2050 within the NZE framework (IEA, 2022; OIES, 2024). Dispatchable electricity sources have historically constituted the primary mechanism for ensuring system adequacy, a trend that endures within the NZE paradigm, especially as electricity systems undergo evolution marked by an escalating reliance on variable solar photovoltaic (PV) and wind energy sources (Marzouk, 2024; Moon et al., 2024; Wisnubroto et al., 2023). It is indisputable that unabated fossil fuel resources predominantly dominate dispatchable capacity; however, their prominence clearly diminishes, declining by a quarter by 2030 within the NZE framework and experiencing a precipitous decline thereafter. Unabated coal-fired power, currently the most substantial dispatchable source, anticipates a decline exceeding 40% in operational capacity by 2030 and approaches a state of negligible contribution by the early 2040s. Conversely, the unabated natural gas-fired power capacity exhibits a sustained level of stability until 2030, primarily driven by the necessity to offset the diminishing role of coal; nonetheless, it subsequently undergoes a rapid descent throughout the 2030s. Oil, constituting a comparatively minor contributor, experiences rapid phasing out across most regions, except for remote locales, within the delineated scenario (Makarov et al., 2023; Ren et al., 2024). Figure 4 highlights the global capacity of dispatchable power categorized by category in the scenario of achieving NZE by 2050.   In this context, fossil fuels equipped with Carbon Capture, Utilization, and Storage (CCUS) technology have emerged as notable contributors to bolstering system adequacy. Yet, nuclear power remains a steady contributor to the power system flexibility. In advanced economies, the proportion of hour-to-hour flexibility is projected to increase from approximately 2% to 5% by 2050. Similarly, in EMDEs, this ratio is anticipated to increase from 1% to 3% over the same temporal span (Jenkins et al., 2018). It is worth highlighting that in France, where nuclear power fulfills the lion's share of electricity generation requisites, flexibility has been ingrained within reactor designs (Ho et al., 2019). This feature enables certain plants to swiftly modulate their output to align with the fluctuating electricity supply and demand, operating in a load-following mode (Chen, 2024; Jin and Bae, 2023; Kanugrahan and Hakam, 2023). Although many nations have not habitually engaged nuclear power in such operational dynamics, a considerable number of reactors are capable of performing load-following operations with minimal or no requisite technical adaptations (Caciuffo et al., 2020). Figure 5 demonstrates the hour-to-hour power system flexibility based on the source and regional grouping in the NZE by the 2050 scenario.   Innovation holds promise in enhancing the flexibility of nuclear power. Advanced technological advancements, such as SMRs, can facilitate nuclear reactors to adjust their electricity output with greater ease, as illustrated in Figure 6 (Ho et al., 2019; Lee, 2024; Wisnubroto et al., 2023). Moreover, these technologies offer the prospect of enabling reactors to transition toward generating heat or producing hydrogen either independently or concurrently with electricity generation. Initiatives are underway to disseminate information to policymakers and planners regarding the potential cost advantages associated with enhancing nuclear power flexibility.  Figure 6 demonstrates the nuclear system augmented by wind turbines for trigeneration.   Investment in nuclear power The renaissance of nuclear power within the NZE trajectory necessitates a substantial surge in investment in the coming decades. This surge is envisaged to encompass the construction of new nuclear reactors and extension of operational lifespans for existing facilities. Within this scenario, annual global investment in nuclear power is poised to escalate to exceed US$100 billion during the initial half of the 2030s within the NZE framework, surpassing the threefold average investment level of US$30 billion recorded during the 2010s (IEA, 2022). Subsequently, investment levels are expected to gradually decline as the imperative for dispatchable low emissions generating capacity diminishes, tapering to approximately US$70 billion by the latter half of the 2040s (Kharitonov and Semenova, 2023; Zimmermann and Keles, 2023). Over the period spanning from 2021 to 2050, the allocation of investment toward nuclear power constitutes a fraction representing less than 10% of the aggregate investment dedicated to low-emission sources of electricity (IEA, 2022). By comparison, within this framework, the annual investment in renewable energy experiences a notable escalation, escalating from an average of US$325 billion during the interval from 2016 to 2020 to US$1.3 trillion during the period 2031–2035 (EEDP, 2023; Rekik and El Alimi, 2024d). It is worth noting that the latter consideration elucidates the rationale behind the disproportionate allocation of investment toward advanced economies in later decades. China, for instance, requires an annual expenditure averaging close to US$20 billion on nuclear infrastructure by 2050, representing a nearly twofold increase compared to the average observed during the 2010s (Aghahosseini et al., 2023; Vujić et al., 2012). Conversely, other EMDEs witness a tripling of investment, reaching approximately US$25 billion per year, on average. In contrast to advanced economies, the imperative for investment in these nations is more pronounced in the period leading up to 2035 (Bhattacharyya et al., 2023; Khaleel et al., 2024). Thus, nuclear energy, despite its advantages as a low-carbon energy source, faces notable challenges. High capital costs and long deployment timelines, driven by complex construction and regulatory requirements, often hinder its adoption. The management of radioactive waste remains a costly and contentious issue, while safety concerns, shaped by historical incidents, continue to influence public perception. Additionally, reliance on uranium, with its geographically concentrated supply, raises geopolitical and environmental concerns. Nuclear power also competes with the rapidly advancing and cost-effective renewable energy sector, while decommissioning aging plants poses long-term financial and logistical burdens. Addressing these limitations through advanced technologies, public engagement, and international collaboration is crucial for enhancing nuclear energy's role in sustainable energy transitions. Technologies for sustainability in nuclear energy production The pursuit of sustainability in nuclear energy production has been supported by advancements in innovative technologies that enhance efficiency, safety, and environmental compatibility (Aktekin et al., 2024; Ali et al., 2024; Zheng et al., 2024; Khan et al., 2017). These technologies are crucial for positioning nuclear power as a key contributor to clean and sustainable energy transitions. Below are some of the most impactful technologies in this domain: Advanced nuclear reactors: Small modular reactors (SMRs): SMRs are compact, scalable, and safer than traditional large-scale reactors. Their modular design allows for deployment in remote locations, making them suitable for decentralized energy systems. Generation IV reactors: These reactors incorporate advanced cooling systems and fuel cycles to improve efficiency, safety, and waste reduction. Examples include sodium-cooled fast reactors and gas-cooled fast reactors. Thorium-based reactors: Thorium fuel cycle reactors use thorium-232 as an alternative to uranium, offering a more abundant and sustainable fuel source. Thorium reactors produce less nuclear waste and have a lower risk of proliferation. Fusion energy: Although still in the experimental stage, nuclear fusion promises to be a game-changing technology. Fusion produces minimal radioactive waste and harnesses abundant fuel sources like deuterium and tritium, making it a virtually limitless and clean energy solution. Molten salt reactors (MSRs): MSRs use liquid fuels or coolants, such as molten salts, which operate at lower pressures and higher temperatures. These reactors are inherently safer and have the capability to utilize a variety of fuel types, including spent nuclear fuel and thorium. Reactor safety enhancements: Passive safety systems: These systems enhance reactor safety by using natural forces like gravity, natural convection, or condensation to cool the reactor core without human intervention. Digital twin technologies: Digital simulations and monitoring of reactor systems allow for predictive maintenance and real-time safety management. Nuclear waste management technologies Fast reactors: These reactors can recycle spent fuel, reducing the volume and radioactivity of nuclear waste. Deep geological repositories: Advances in geotechnical engineering have improved the safety of long-term waste storage in deep geological formations. Hybrid nuclear-renewable systems: Combining nuclear power with renewable energy sources like wind and solar can optimize energy production and grid stability. Hybrid systems leverage the reliability of nuclear energy with the intermittency of renewables for a balanced, low-carbon energy mix. Artificial intelligence (AI) and machine learning: AI and machine learning technologies are being deployed to enhance reactor performance, optimize fuel usage, and improve operational safety. Predictive analytics also play a critical role in maintenance and risk assessment. Fuel advancements: High-assay low-enriched uranium (HALEU): HALEU fuels enable reactors to operate more efficiently and reduce waste. Accident-tolerant fuels (ATFs): These are designed to withstand extreme conditions, reducing the likelihood of core damage during accidents. Integrated energy systems: Nuclear reactors are increasingly being used for purposes beyond electricity generation, such as hydrogen production, district heating, and desalination. The integration of digital technologies, including AI and machine learning, coupled with fuel advancements like HALEU and accident-tolerant fuels, highlights the continuous evolution of the nuclear sector. These innovations not only enhance efficiency and safety but also expand the applications of nuclear energy beyond electricity generation to include hydrogen production, desalination, and district heating. Despite these technological advancements, the sustainable deployment of nuclear energy requires robust policy frameworks, increased investments, and public acceptance. Addressing these challenges is critical to unlocking the full potential of nuclear power in achieving global energy security and NZE by 2050. [...] Discussion and policy implications Nuclear power presents a compelling case as a sustainable energy source owing to its several key advantages. Its high-energy density allows for substantial electricity generation from minimal fuel, enabling continuous operation, unlike intermittent renewables, such as solar and wind (Rekik and El Alimi, 2023a, 2023b), thus contributing significantly to grid stability (Cramer et al., 2023). Furthermore, nuclear power is a crucial tool for emissions reduction, boasting virtually no greenhouse gas emissions during operation. Although lifecycle emissions associated with fuel processing and plant construction exist, they remain comparable to or lower than those of renewables. Several studies have reported on the energy production capabilities of nuclear power and its contribution to reducing greenhouse gas emissions compared to other energy sources. A key aspect of these analyses is quantifying the potential contribution of nuclear power to reducing greenhouse gas emissions and achieving net zero targets. However, direct comparison of reported data can be challenging due to variations in model assumptions, geographic scope, and time horizons.  [...] From another perspective, radioactive waste generation poses a significant challenge to nuclear power because of its long-term hazardous nature. This necessitates meticulous management and disposal strategies to mitigate potential social impacts. These impacts arise from perceived or actual risks to human health and the environment, fueling public anxiety and opposition to nuclear power, which is often expressed through protests and legal action (Kyne and Bolin, 2016; Nilsuwankosit, 2017; Ram Mohan and Namboodhiry, 2020). Additionally, communities near waste sites can experience stigmatization, resulting in decreased property values and social isolation. The persistent nature of radioactive waste also raises intergenerational equity issues, burdening future generations with its management (Deng et al., 2020; Mason-Renton and Luginaah, 2019). Thus, transparent communication and stakeholder engagement are crucial for building public trust and ensuring responsible radioactive waste management (Dungan et al., 2021; Sančanin and Penjišević, 2023). There are various radioactive waste disposal pathways, each with unique social and technical considerations. Deep geological disposal, an internationally favored method for high-level waste disposal, involves burying waste deep underground for long-term isolation. Interim storage provides a secure temporary holding until a permanent solution is obtained (Chapman, 1992; Grambow, 2022). Reprocessing spent nuclear fuel recovers reusable materials, reducing high-level waste but creating lower-level waste. Advanced reactor technologies aim to minimize waste and improve safety, potentially converting long-lived isotopes into shorter-lived isotopes (Dixon et al., 2020; Englert and Pistner, 2023). Choosing a disposal pathway requires careful evaluation of factors, such as waste type and volume, geology, feasibility, cost, and public acceptance, often leading to a combined approach. Ongoing community engagement and addressing concerns are essential to safe and responsible waste management. Effective management and disposal of this waste require advanced technological solutions, robust regulatory frameworks, and long-term planning to ensure safety and sustainability (Abdelsalam et al., 2024; Rekik and El Alimi, 2024a), Moreover, its relatively small land footprint compared to other energy sources, especially solar and wind farms, minimizes the ecosystem impact and makes it a sustainable option in densely populated areas (Poinssot et al., 2016; Sadiq et al., 2022). Nuclear power also enhances energy security by reducing reliance on fossil fuels, which is particularly valuable in countries with limited domestic resources (Cramer et al., 2023; Ichord Jr., 2022). Additionally, nuclear power exhibits synergy with other clean technologies, providing a stable baseload complementing variable renewables and facilitating hydrogen production for diverse energy applications (Abdelsalam et al., 2024; El-Emam and Subki, 2021; Salam and Khan, 2018; Rekik, 2024; Rekik and El Alimi, 2024e). Finally, ongoing advancements in reactor design, such as SMRs, promise enhanced safety, reduced costs, and greater deployment flexibility, further solidifying the role of nuclear power in decarbonizing the electricity sector (Aunedi et al., 2023). Supportive policies and international cooperation are essential for fully realizing the potential of nuclear energy. Streamlined licensing and regulatory frameworks are crucial for reducing deployment time and costs and ensuring that safety standards are met efficiently (Gungor and Sari, 2022; Jewell et al., 2019). Furthermore, incentivizing investments through financial tools such as tax credits and loan guarantees can attract private capital and create a level-playing field for nuclear power (Decker and Rauhut, 2021; Nian and Hari, 2017; Zimmermann and Keles, 2023). Addressing public perception through education and engagement is equally important for building trust and acceptance. Moreover, international cooperation is vital in several respects. The disposal of radioactive waste remains a complex issue, requiring careful long-term management and securing geological repositories to prevent environmental contamination owing to the long half-life of some isotopes. Furthermore, while modern reactors incorporate advanced safety features, the potential for accidents such as Chernobyl and Fukushima remains a concern because of the potential for widespread radiation release and long-term health consequences (Denning and Mubayi, 2016; Högberg, 2013; Wheatley et al., 2016). Moreover, the high initial costs associated with design, construction, and licensing present significant barriers to new nuclear projects, particularly in developing countries. In addition, the risk of nuclear proliferation, in which technology intended for peaceful energy production is diverted for weapons development, necessitates stringent international safeguards, as highlighted by following reference. Public perception also plays a crucial role because negative opinions and concerns about safety and waste disposal can create opposition to new projects. Finally, the decommissioning of nuclear plants at the end of their operational life is a complex and costly process that requires substantial resources and expertise to dismantle reactors and manage radioactive materials. [...] Conclusion The role of nuclear power in sustainable energy transition is multifaceted and significant. As nations worldwide strive to transition toward more environmentally friendly energy systems, nuclear power has emerged as a crucial component of the decarbonization journey. Its capacity to provide low-carbon electricity, mitigate climate change, and contribute to energy security underscores its importance in the broader context of sustainable energy transitions. Despite this, challenges such as safety, waste management, and public perception must be addressed to fully harness the potential of nuclear power to achieve sustainability goals. By leveraging policy frameworks, technological innovations, and international cooperation, nuclear power can play a vital role in shaping the future of sustainable energy transition on a global scale. In this context, EMDEs exert a substantial influence on global growth, collectively accounting for over 90% of the aggregate, with China positioned to emerge as the foremost nuclear power producer before 2030. Concurrently, advanced economies have witnessed a notable 10% increase in their nuclear power capacity. This augmentation is attributed to the commissioning of new facilities, which offset retirements, manifestly observed in nations such as the United States, France, the United Kingdom, and Canada. Furthermore, there is a marked escalation in annual global investment in nuclear power, surging from US$30 billion throughout the 2010s to surpass US$100 billion by 2030. This upward trajectory is robustly sustained, remaining above US$80 billion by 2050. In conclusion, the remarkable decline in the levelized cost of electricity (LCOE) for solar PV and wind power over the past decade has positioned renewable energy as a cost-competitive and viable alternative to fossil fuels in many regions. The over 80% reduction in LCOE for utility-scale solar PV from 2010 to 2022 exemplifies the economic feasibility of renewables. Concurrently, the steady growth in renewable energy capacity, spearheaded by solar and wind energy, underscores their critical role in the global energy transition. With renewable electricity capacity surpassing 3300 GW in 2023 and accounting for over one-third of the global power mix, renewable energy is undeniably at the forefront of efforts to achieve a sustainable, low-carbon energy future. Declaration of conflicting interestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.FundingThe authors received no financial support for the research, authorship, and/or publication of this article.ORCID iDSassi Rekik https://orcid.org/0000-0001-5224-4152Supplemental materialSupplemental material for this article is available online.ReferencesAbbasi K, Jiao Z, Shahbaz M, et al.

Abstract We examine the roles of Gold and Bitcoin as a hedge, a safe haven, and a diversifier against the coronavirus disease 2019 (COVID-19) pandemic and the Ukraine War. Using a rolling window estimation of the dynamic conditional correlation (DCC)-based regression, we present a novel approach to examine the time-varying safe haven, hedge, and diversifier properties of Gold and Bitcoin for equities portfolios. This article uses daily returns of Gold, Bitcoin, S&P500, CAC 40, and NSE 50 from January 3, 2018, to October 15, 2022. Our results show that Gold is a better safe haven than the two, while Bitcoin exhibits weak properties as safe haven. Bitcoin can, however, be used as a diversifier and hedge. This study offers policy suggestions to investors to diversify their holdings during uncertain times. Introduction Financial markets and the diversity of financial products have risen in both volume and value, creating financial risk and establishing the demand for a safe haven for investors. The global financial markets have faced several blows in recent years. From the Global Financial Crisis (GFC) to the outbreak of the pandemic and uncertainty regarding economic policy measures of governments and central banks, the financial markets including equity markets around the world were faced with severe meltdowns. This similar behavior was observed in other markets including equity and commodity markets, resulting in overall uncertainty. In this scenario, the investors normally flock toward the safe-haven assets to protect their investment. In normal situations, investors seek to diversify or hedge their assets to protect their portfolios. However, the financial markets are negatively impacted when there are global uncertainties. Diversification and hedging methods fail to safeguard investors’ portfolios during instability because almost all sectors and assets are negatively affected (Hasan et al., 2021). As a result, investors typically look for safe-haven investments to safeguard their portfolios under extreme conditions (Ceylan, 2022). Baur and Lucey (2010) provide the following definitions of hedge, diversifier, and safe haven: Hedge: An asset that, on average, has no correlation or a negative correlation with another asset or portfolio. On average, a strict hedge has a (strictly) negative correlation with another asset or portfolio.Diversifier: An asset that, on average, has a positive correlation (but not perfect correlation) with another asset or portfolio. Safe haven: This is the asset that in times of market stress or volatility becomes uncorrelated or negatively associated with other assets or a portfolio. As was previously indicated, the significant market turbulence caused by a sharp decline in consumer spending, coupled with insufficient hedging opportunities, was a common feature of all markets during these times (Yousaf et al., 2022). Nakamoto (2008) suggested a remedy by introducing Bitcoin, a “digital currency,” as an alternative to traditional fiduciary currencies (Paule-Vianez et al., 2020). Bitcoin often described as “Digital Gold” has shown greater resilience during periods of crises and has highlighted the potential safe haven and hedging property against uncertainties (Mokni, 2021). According to Dyhrberg (2016), the GFC has eased the emergence of Bitcoin thereby strengthening its popularity. Bouri et al. (2017) in their study indicate that Bitcoin has been viewed as a shelter from global uncertainties caused by conventional banking and economic systems. Recent research has found that Bitcoin is a weak safe haven, particularly in periods of market uncertainty like the coronavirus disease 2019 (COVID-19) crisis (Conlon & McGee, 2020; Nagy & Benedek, 2021; Shahzad et al., 2019; Syuhada et al., 2022). In contrast to these findings, a study by Yan et al. (2022) indicates that it can function as a strong safe haven in favorable economic times and with low-risk aversion. Ustaoglu (2022) also supports the strong safe-haven characteristic of Bitcoin against most emerging stock market indices during the COVID-19 period. Umar et al. (2023) assert that Bitcoin and Gold are not reliable safe-havens. Singh et al. (2024) in their study reveal that Bitcoin is an effective hedge for investments in Nifty-50, Sensex, GBP–INR, and JPY–INR, at the same time a good diversifier for Gold. The study suggests that investors can incorporate Bitcoin in their portfolios as a good hedge against market volatility in equities and commodities markets. During the COVID-19 epidemic, Barbu et al. (2022) investigated if Ethereum and Bitcoin could serve as a short-term safe haven or diversifier against stock indices and bonds. The outcomes are consistent with the research conducted by Snene Manzli et al. (2024). Both act as hybrid roles for stock market returns, diversifiers for sustainable stock market indices, and safe havens for bond markets. Notably, Bhuiyan et al. (2023) found that Bitcoin provides relatively better diversification opportunities than Gold during times of crisis. To reduce risks, Bitcoin has demonstrated a strong potential to operate as a buffer against global uncertainty and may be a useful hedging tool in addition to Gold and similar assets (Baur & Lucey, 2010; Bouri et al., 2017; Capie et al., 2005; Dyhrberg, 2015). According to Huang et al. (2021), its independence from monetary policies and minimal association with conventional financial assets allow it to have a safe-haven quality. Bitcoins have a substantial speed advantage over other assets since they are traded at high and constant frequencies with no days when trading is closed (Selmi et al., 2018). Additionally, it has been demonstrated that the average monthly volatility of Bitcoin is higher than that of Gold or a group of international currencies expressed in US dollars; nevertheless, the lowest monthly volatility of Bitcoin is lower than the maximum monthly volatility of Gold and other foreign currencies (Dwyer, 2015). Leverage effects are also evident in Bitcoin returns, which show lower volatilities in high return periods and higher volatilities in low return times (Bouri et al., 2017; Liu et al., 2017). According to recent research, Bitcoins can be used to hedge S&P 500 stocks, which increases the likelihood that institutional and retail investors will build secure portfolios (Okorie, 2020). Bitcoin demonstrates strong hedging capabilities and can complement Gold in minimizing specific market risks (Baur & Lucey, 2010). Its high-frequency and continuous trading further enrich the range of available hedging tools (Dyhrberg, 2016). Moreover, Bitcoin spot and futures markets exhibit similarities to traditional financial markets. In the post-COVID-19 period, Zhang et al. (2021) found that Bitcoin futures outperform Gold futures.Gold, silver, palladium, and platinum were among the most common precious metals utilized as safe-haven investments. Gold is one such asset that is used extensively (Salisu et al., 2021). Their study tested the safe-haven property of Gold against the downside risk of portfolios during the pandemic. Empirical results have also shown that Gold functions as a safe haven for only 15 trading days, meaning that holding Gold for longer than this period would result in losses to investors. This explains why investors buy Gold on days of negative returns and sell it when market prospects turn positive and volatility decreases (Baur & Lucey, 2010). In their study, Kumar et al. (2023) tried to analyse the trends in volume throughout futures contracts and investigate the connection between open interest, volume, and price for bullion and base metal futures in India. Liu et al. (2016) in their study found that there is no negative association between Gold and the US stock market during times of extremely low or high volatility. Because of this, it is not a strong safe haven for the US stock market (Hood & Malik, 2013). Post-COVID-19, studies have provided mixed evidence on the safe-haven properties of Gold (Bouri et al., 2020; Cheema et al., 2022; Ji et al., 2020). According to Kumar and Padakandla (2022), Gold continuously demonstrates safe-haven qualities for all markets, except the NSE, both in the short and long term. During the COVID-19 episode, Gold’s effectiveness as a hedge and safe-haven instrument has been impacted (Akhtaruzzaman et al., 2021). Al-Nassar (2024) conducted a study on the hedge effectiveness of Gold and found that it is a strong hedge in the long run. Bhattacharjee et al. (2023) in their paper examined the symmetrical and asymmetrical linkage between Gold price levels and the Indian stock market returns by employing linear autoregressive distributed lag and nonlinear autoregressive distributed lag models. The results exhibit that the Indian stock market returns and Gold prices are cointegrated. According to the most recent study by Kaczmarek et al. (2022), Gold has no potential as a safe haven, despite some studies on the COVID-19 pandemic showing contradictory results. The co-movements of Bitcoin and the Chinese stock market have also normalized as a result of this epidemic (Belhassine & Karamti, 2021). Widjaja and Havidz (2023) verified that Gold was a safe haven asset during the COVID-19 pandemic, confirming the Gold’s safe-haven characteristic. As previously pointed out, investors value safe-haven investments in times of risk. Investors panic at these times when asset prices fall and move from less liquid (risky) securities to more liquid (safe) ones, such as cash, Gold, and government bonds. An asset must be bought and sold rapidly, at a known price, and for a reasonably modest cost to be considered truly safe (Smales, 2019). Therefore, we need to properly re-examine the safe-haven qualities of Gold and Bitcoin due to the mixed evidences regarding their safe-haven qualities and the impact of COVID-19 and the war in Ukraine on financial markets. This work contributes to and deviates from the body of existing literature in the following ways. We propose a novel approach in this work to evaluate an asset’s time-varying safe haven, hedge, and diversifier characteristics. This research examines the safe haven, hedging, and diversifying qualities of Gold and Bitcoin against the equity indices; S&P 500, CAC 40, and NSE 50. Through the use of rolling window estimation, we extend the methodology of Ratner and Chiu (2013) by estimating the aforementioned properties of the assets. Comparing rolling window estimation to other conventional techniques, the former will provide a more accurate representation of an asset’s time-varying feature. This study explores the conventional asset Gold’s time-varying safe haven, hedging, and diversifying qualities during crises like the COVID-19 pandemic and the conflict in Ukraine. We use Bitcoin, an unconventional safe-haven asset, for comparison. Data and Methodology We use the daily returns of three major equity indices; S&P500, CAC 40, and NSE 50 from January 3, 2018, to October 15, 2022. The equity indices were selected to represent three large and diverse markets namely the United States, France, and India in terms of geography and economic development. We assess safe-haven assets using the daily returns of Gold and Bitcoin over the same time. Equity data was collected from Yahoo Finance, Bitcoin data from coinmarketcap.com, and Gold data from the World Gold Council website. Engle (2002) developed the DCC (Dynamic Conditional Correlation)-GARCH model, which is frequently used to assess contagion amid pandemic uncertainty or crises. Time-varying variations in the conditional correlation of asset pairings can be captured using the DCC-GARCH model. Through employing this model, we can analyse the dynamic behavior of volatility spillovers. Engle’s (2002) DCC-GARCH model contains two phases; 1. Univariate GARCH model estimation2. Estimation of time-varying conditional correlation. For its explanation, mathematical characteristics, and theoretical development, see here [insert the next link in “the word here” https://journals.sagepub.com/doi/10.1177/09711023251322578] Results and Discussion The outcomes of the parameters under the DCC-GARCH model for each of the asset pairs selected for the investigation are shown in Table 1.   First, we look at the dynamical conditional correlation coefficient, ρ.The rho value is negative and insignificant for NSE 50/Gold, NSE 50 /BTC, S&P500/Gold, and S&P500/BTC indicating a negative and insignificant correlation between these asset pairs, showing Gold and Bitcoin as potential hedges and safe havens. The fact that ρ is negative and significant for CAC 40/Gold suggests that Gold can be a safe haven against CAC 40 swings. The asset pair CAC/BTC, on the other hand, has possible diversifier behavior with ρ being positive but statistically insignificant. Next, we examine the behavior of the DCC-GARCH parameters; α and β. We find that αDCC is statistically insignificant for all the asset pairs, while βDCC is statistically significant for all asset pairs. βDCC quantifies the persistence feature of the correlation and the extent of the impact of volatility spillover in a particular market’s volatility dynamics. A higher βDCC value implies that a major part of the volatility dynamics can be explained by the respective market’s own past volatility. For instance, the NSE 50/Gold’s βDCC value of 0.971 shows that there is a high degree of volatility spillover between these two assets, with about 97% of market volatility being explained by the assets’ own historical values and the remainder coming from spillover. Thus, we see that the volatility spillover is highly persistent (~0.8) for all the asset pairs except NSE 50/BTC. The results above show that the nature of the dynamic correlation between the stock markets, Bitcoin and Gold is largely negative, pointing toward the possibility of Gold and Bitcoin being hedge/safe haven. However, a detailed analysis is needed to confirm the same by employing rolling window analysis, and we present the results in the forthcoming section. We present the rolling window results for S&P500 first. We present the regression results for Gold in Figure 1 and Bitcoin in Figure 2   Figure 1. Rolling Window Regression Results for S&P500 and Gold.Note: Areas shaded under factor 1 represent significant regression coefficients. In Figure 1, we examine the behavior of β0 (intercept term), β1, β2, and β3 (partial correlation coefficients). The intercept term β0 will give an idea about whether the asset is behaving as a diversifier or hedge. Here, the intercept term shows significance most of the time. However, during 2018, the intercept was negative and significant, showing that it could serve as a hedge during geopolitical tensions and volatilities in the global stock market. However, during the early stages of COVID-19, we show that the intercept is negative and showing statistical significance, suggesting that Gold could serve as a hedge during the initial shocks of the pandemic. These findings are contrary to the results in the study by Tarchella et al. (2024) where they found hold as a good diversifier. Later, we find the intercept to be positive and significant, indicating that Gold could act as a potential diversifier. But during the Russia-Ukraine War, Gold exhibited hedge ability again. Looking into the behavior of β1, which is the partial correlation coefficient for the tenth percentile of return distribution shows negative and insignificant during 2018. Later, it was again negative and significant during the initial phases of COVID-19, and then negative in the aftermath, indicating that Gold could act as a weak safe haven during the COVID-19 pandemic. Gold could serve as a strong safe haven for the SP500 against volatility in the markets brought on by the war in Ukraine, as we see the coefficient to be negative and large during this time. From β2 and β3, the partial correlation coefficients of the fifth and first percentile, respectively, show that Gold possesses weak safe haven properties during COVID-19 and strong safe haven behavior during the Ukraine crisis. Next, we examine the characteristics of Bitcoin as a hedge/diversifier/safe haven against the S&P500 returns. We present the results in Figure 2.   Figure 2. Rolling Window Regression Results for S&P500 and Bitcoin.Note: Areas shaded under factor 1 represent significant regression coefficients. Like in the previous case, we begin by analysing the behavior of the intercept coefficient, which is β0. As mentioned earlier the intercept term will give a clear picture of the asset’s hedging and diversifier property. In the period 2018–2019, the intercept term is positive but insignificant. This could be due to the large volatility in Bitcoin price movements during the period. It continues to be minimal (but positive) and insignificant during 2019–2020, indicating toward weak diversification possibility. Post-COVID-19 period, the coefficient shows the significance and positive value, displaying the diversification potential. We see that the coefficient remains positive throughout the analysis, confirming Bitcoin’s potential as a diversifier. Looking into the behavior of β1 (the partial correlation coefficient at tenth percentile), it is positive but insignificant during 2018. The coefficient is having negative sign and showing statistical significance in 2019, suggesting that Bitcoin could be a good safe haven in that year. This year was characterized by a long list of corporate scandals, uncertainties around Brexit, and tensions in global trade. We can observe that throughout the COVID-19 period, the coefficient is showing negative sign and negligible during the March 2020 market meltdown, suggesting inadequate safe-haven qualities. However, Bitcoin will regain its safe-haven property in the coming periods, as the coefficient is negative and significant in the coming months. The coefficient is negative and shows statistical significance during the Ukrainian crisis, suggesting strong safe-haven property. Only during the Ukrainian crisis could Bitcoin serve as a safe haven, according to the behavior of β2, which displays the partial correlation coefficient at the fifth percentile. Bitcoin was a weak safe haven during COVID-19 and the Ukrainian crisis, according to β3, the partial correlation coefficient for the first percentile (coefficient negative and insignificant). According to the overall findings, Gold is a stronger safe haven against the S&P 500’s swings. This result is consistent with the previous studies of Triki and Maatoug (2021), Shakil et al. (2018), Będowska-Sójka and Kliber (2021), Drake (2022), and Ghazali et al. (2020), etc. The same analysis was conducted for the CAC 40 and the NSE 50; the full analysis can be found here [insert the next link in “the word here” https://journals.sagepub.com/doi/10.1177/09711023251322578]. However, it is important to highlight the respective results: In general, we may say that Gold has weak safe-haven properties considering CAC40. We can conclude that Bitcoin’s safe-haven qualities for CAC40 are weak. We can say that Gold showed weak safe-haven characteristics during the Ukraine crisis and good safe-haven characteristics for the NSE50 during COVID-19. We may say that Bitcoin exhibits weak safe haven, but strong hedging abilities to NSE50. Concluding Remarks In this study, we suggested a new method to evaluate an asset’s time-varying hedge, diversifier, and safe-haven characteristics. We propose a rolling window estimation of the DCC-based regression of Ratner and Chiu (2013). Based on this, we estimate the conventional asset’s time-varying safe haven, hedging, and diversifying properties during crises like the COVID-19 pandemic and the conflict in Ukraine. For comparison purposes, we include Bitcoin, a nonconventional safe-haven asset. We evaluate Gold and Bitcoin’s safe haven, hedging, and diversifier properties to the S&P 500, CAC 40, and NSE 50 variations. We use a rolling window of length 60 to estimate the regression. From the results, we find that Gold can be considered as a better safe haven against the fluctuations of the S&P 500. In the case of CAC 40, Gold and Bitcoin have weak safe-haven properties. While Bitcoin demonstrated strong safe-haven characteristics during the Ukraine crisis, Gold exhibited strong safe-haven characteristics during COVID-19 for the NSE 50. Overall, the findings indicate that Gold is the better safe haven. This outcome is consistent with earlier research (Będowska-Sójka & Kliber, 2021; Drake, 2022; Ghazali et al., 2020; Shakil et al., 2018; Triki & Maatoug, 2021). When it comes to Bitcoin, its safe-haven feature is weak. Bitcoin, however, works well as a diversifier and hedge. Therefore, from a policy perspective, investing in safe-haven instruments is crucial to lower the risks associated with asset ownership. Policymakers aiming to enhance the stability of financial portfolios might encourage institutional investors and other market players to incorporate Gold into their asset allocations. Gold’s strong safe-haven qualities, proven across various market conditions, make it a reliable choice. Gold’s performance during crises like COVID-19 highlights its potential to mitigate systemic risks effectively. Further, Bitcoin could also play a complementary role as a hedge and diversifier, especially during periods of significant volatility such as the Ukraine crisis. While Bitcoin’s safe-haven characteristics are relatively weaker, its inclusion in a diversified portfolio offers notable value and hence it should not be overlooked. Further, policymakers may consider how crucial it is to monitor dynamic correlations and periodically rebalance portfolios to account for shifts in the safe haven and hedging characteristics of certain assets. Such measures could help reduce the risks of over-reliance on a single asset type and create more resilient portfolios that can better withstand global economic shocks. For future research, studies can be conducted on the estimation of the rolling window with different widths. This is important to understand how the safe-haven property changes across different holding periods. Further, more equity markets would be included to account for the differences in market capitalization and index constituents. This study can be extended by testing these properties for multi-asset portfolios as well. We intend to take up this study in these directions in the future. Data Availability StatementNot applicable.Declaration of Conflicting InterestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.FundingThe authors received no financial support for the research, authorship, and/or publication of this article.ReferencesAkhtaruzzaman M., Boubaker S., Lucey B.

In a landmark advisory opinion, the International Court of Justice (ICJ) ruled on 23 July 2025 that all UN member states have legal obligations under international law to address climate change, which the court described as an existential threat to life on Earth. Powerful countries too must be held responsible for their current emissions and past inaction. Possibly in anticipation of such a ruling, Chris Wright, the US Secretary of Energy and former chief executive of Liberty Energy (an oilfield services company), published an article in The Economist a week earlier, arguing that “climate change is a by-product of progress, not an existential crisis”. Whereas the ICJ relied primarily on the IPCC reports, “which participants agree constitute the best available science on the causes, nature and consequences of climate change”, Wright’s view is based on a particular temporal logic.  According to the IPCC reports, most greenhouse gases come from burning fossil fuels, with additional emissions from agriculture, deforestation, industry, and waste. They drive global warming, which is projected to reach 1.5°C between 2021 and 2040, with 2°C likely to follow. Even 1.5°C is not considered safe for most nations, communities, and ecosystems, and according to IPCC, only deep, rapid, and sustained emission cuts can slow warming and reduce the escalating risks and damages. The 2024 state of the climate report, published in BioScience, presents even more worrying assessments. Among other things, the report cites surveys indicating that nearly 80% of these scientists anticipate global temperatures increasing by at least 2.5°C above preindustrial levels by the end of the century, and nearly half of them foresee a rise of at least 3°C.  Wright’s article suggests that the issue of amplifying doubt about climate change may have little to do with engagement with science but rather reflects a deeper temporal logic. This logic is rooted in a Whiggish account of progress to date, a resistance to the reality of the future and the desire for nostalgic restoration. I will explain these elements one by one. The first tier: Whiggism Wright disagrees with most scientific anticipations. His views are likely representative not only of the Trump II administration but also of conservative right-wing populism more generally. It is difficult to understand their climate denialism without an analysis of their views on time and temporality. The most important question concerns the reality of the future. At the first level, Wright provides a kind of textbook example of Whig history, portraying progress as linear, inevitable, and driven by liberal values. Herbert Butterfield introduced the idea of Whig history in his influential 1931 book The Whig Interpretation of History as a critique of a specific way of writing history that he regarded as flawed and intellectually dishonest. Focusing on inevitable progress distorts historical analysis by promoting simplified cause-and-effect reasoning and selective storytelling, emphasising present-day evaluation (and glorification) over understanding the real causes of historical change. In a Whiggish manner, Wright claims that the last 200 years have seen two big changes to the human condition: “human liberty” and affordable energy. As a result of these two things, life expectancy has nearly doubled, and the percentage of people living in extreme poverty has dropped from 90% to 10%. However, Wright’s argumentation is based on non-contextual and, in that sense, timeless representations of the world, despite its “progressivism”.  For example, consider the claim that extreme poverty has dropped from 90% to 10%. It is based on using a fixed dollar threshold, such as USD 2 per day, to measure poverty over 200 years. This is misleading because most people in the 19th century lived in largely non-monetised economies where subsistence needs were met outside of market exchange, and monetary income was minimal or irrelevant. These metrics also obscure shifting and context-bound definitions of basic needs; rely on incomplete historical data; and ignore the role of colonial dispossession and structural inequality in shaping global poverty. While it is true that life expectancy has doubled, largely due to improvements in hygiene and healthcare, the idea that extreme poverty has plummeted from 90% to under 10% also ignores the fact that the global population has grown eightfold, affecting the entire Earth system with devastating ecological and geological consequences. It further ignores that the rise in life expectancy and poverty reduction has come not only from liberalism or economic growth more generally but from ethical and political struggles and public health interventions. Often, these struggles have been fought in the name of socialism and won despite capitalist incentives, market mechanisms, and related political forces. The second tier: blockism At a deeper level, Wright’s views seem to presuppose what Roy Bhaskar calls “blockism”: the postulation of a simultaneous conjunctive totality of all events. This may sound abstract, but it has been a common assumption among many 20th-century physicists and philosophers that the universe forms a static, closed totality. This view stems from an atomist ontology, where individuals are seen as abstract, events follow regular patterns, time is viewed as spatial, and laws that can be expressed mathematically are considered reversible.  In such a conception, time appears as just another “spatial” dimension. According to the block universe model, the past, present, and future all exist equally and tenselessly. The universe is imagined as a four-dimensional geometric object, like a “block” of spacetime. Time is not something that “flows” or “passes”; instead, all moments are spatially extended points in a timeless whole. Blockism suggests that change and becoming are not truly real but are simply parts of our subjective experience.  The real challenge is to reconcile Whiggism and blockism. Wright is not a theorist and might not need to worry about the coherence of his ideas, but the issue is that Whiggism assumes movement, direction, and a normatively positive evolution of change, whereas the block universe denies real temporality: there is no becoming, no novelty, no agency – only timeless existence. Some versions of the block universe attempt to preserve development by proposing that the block grows. The “block” expands as new events are added to reality, but in this view, the present defines the upper boundary of the block, and the future is not truly real. This appears to be consistent with what Wright says about climate change. Everything he has to say about global warming is limited to one short paragraph: We will treat climate change as what it is: not an existential crisis but a real, physical phenomenon that is a by-product of progress. Yes, atmospheric CO2 has increased over time – but so has life expectancy. Billions of people have been lifted out of poverty. Modern medicine, telecommunications and global transportation became possible. I am willing to take the modest negative trade-off for this legacy of human advancement. From the ICJ’s perspective, this interpretation is dreadful, as the current impacts of climate change are already at odds with the rights of many groups of people. It also exhibits basic injustice, as many of the groups that suffer the most from these impacts have done next to nothing to cause the problem. However, here I am mostly concerned with the temporality of Wright’s claims. This temporality is a combination of Whiggism and blockism: so far, history has exhibited progress, but time and processes stop here, in our present moment. The third tier: nostalgia Wright’s view of time is not limited to an ultimately incoherent combination of Whiggism and blockism. There is also more than a mere hint of nostalgia. This is evident in the appeal of a Golden Age at the outset of his article: I am honoured to advance President Donald Trump’s policy of bettering lives through unleashing a golden age of energy dominance – both at home and around the world. The appeal to the Golden Age somewhat contradicts Whiggism. From a nostalgic perspective, it seems that society has been on a downward trajectory instead of progressing. In other words, regression must be possible. Within an overall Whiggish narrative, one can blame certain actors, such as the Democrats in the US political context, for causing moral and political decline.  A nationalist narrative of a “golden age” and a return to a better past (“making us great again”) is essentially connected to the denial of planetary-scale problems, such as climate change, that would clearly require novel global responses. Climate change from a real-time perspective By merging Whiggism with a block-universe ontology (either static or growing), one ends up with a pseudo-historicism that speaks of “progress” while erasing real time. In a way, such a view “performs change” through a highly selective historical narrative, while denying the ontological preconditions of real change. Real change – emergence, transformation, causation – requires a temporal ontology, where the future is real though not yet fully determined. Thus, there is no mention of global emissions that have continued to rise, their delayed effects, feedback loops, or emergent risks given multiple processes of intertwined changes. Are the basic IPCC models based on real historical time? IPCC models often treat the climate system as a bounded system with internally consistent and deterministic dynamics. The IPCC relies on modelling and uses Bayesian methods to assess uncertainties in climate projections. Bayesian statistics involve updating the probability of a hypothesis as more evidence becomes available, based on prior knowledge (priors) and new data (likelihoods). Such an approach tends to be conservative (based on moving averages, for example) and assumes the quantifiability of uncertainty. It may also convey illusory precision, especially when the underlying models or data are uncertain or incomplete. The IPCC models nonetheless indicate – in contrast to Wright – that the future is real, though the future is approached in a somewhat cautious and deterministic manner. However, many climate scientists go beyond the IPCC consensus by assuming that global heating may reach 2.5 °C or even above 3 °C degree warming by the end of the century.  From a critical scientific realist viewpoint, even such anticipations may be too circumspect. Assuming exponential growth (involving cascading events etc.) and given that recent data shows a rise from 1.0°C to 1.5°C in just 15 years (actual data taken on an annual basis, not moving averages), and using this as a basis for anticipating the future, we seem likely to reach the 2 °C mark in the 2040s and the 3 °C mark in the 2060s.  The plausibility of anticipations depends significantly on how the real openness of the future is treated. Anticipations are reflexive and can shape the future. Real time and historical change involves human freedom and ethics. The evolving universe, where time is real, is stratified, processual, and open-ended. Time involves genuine processes, real possibilities, agency, and emergent structures. Such characteristics indicate that the future is not predetermined but can be shaped by transformative agency.  To sum up, from a real historical time perspective, Wright’s combination of Whiggism, blockism, and nostalgia is a recipe for reactionary politics. Glorifying the present, thinking in a timeless way, and longing for a golden age of the past can play a major role in bringing about a dystopian planetary future.
