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)
