Carbon dioxide (CO₂) emissions from fossil fuels continue to increase, year on year. This sobering reality will be presented to world leaders today at the international climate conference COP29 in Baku, Azerbaijan. Our latest annual stocktake shows the world is on track to reach a new record: 37.4 billion tonnes of CO₂ emitted from fossil fuels in 2024. This is an increase of 0.8% from the previous year. Adopting renewable energy and electric vehicles is helping reduce emissions in 22 countries.

AbstractEarth System Models (ESMs) continue to diagnose a wide range of carbon budgets for each level of global warming. Here, we present emergent constraints on the carbon budget as a function of global warming, which combine the available ESM historical simulations and future projections for a range of scenarios, with observational estimates of global warming and anthropogenic CO2 emissions to the present day.

AbstractThe Amazon is the largest continuous tropical forest in the world and plays a key role in the global carbon cycle. Human-induced disturbances and climate change have impacted the Amazon carbon balance.

Global carbon dioxide emissions from fossil fuels and cement have increased by 1.1% in 2023, hitting a new record high of 36.8bn tonnes of CO2 (GtCO2), according to the 2023 Global Carbon Budget report by the Global Carbon Project. The new report finds that the increase in fossil emissions in 2023 has been largely driven by increased emissions in China – without which the global total would have remained approximately flat at 2022 levels.

Emisi karbon dioksida (CO2) global dari bahan bakar fosil terus meningkat dengan angka kenaikan pada 2023 sebesar 1,1%. Emisi tersebut mencetak rekor, dengan torehannya sebesar 36,8 miliar ton. Angka ini adalah temuan dari laporan tahunan bujet karbon ke-18 dari Global Carbon Project yang kami rilis 5 Desember lalu. Emisi fosil CO2 berasal dari pembakaran dan penggunaan bahan bakar fosil (batu bara, minyak, dan gas bumi) serta produksi semen.

Les émissions mondiales de dioxyde de carbone (CO2) d’origine fossile augmenteront de 1,1 % en 2023, les portant au niveau record de 36,8 milliards de tonnes de CO2. C’est la conclusion du 18e rapport annuel du Global Carbon Project sur l’état du budget carbone mondial, que nous avons publié aujourd’hui. Le CO2 d’origine fossile comprend les émissions provenant de la combustion et de l’utilisation des énergies fossiles (charbon, pétrole et gaz) et de la production de ciment.

CGRAnnual global atmospheric CGR spanning from 1960 to 2018 is obtained from the Greenhouse Gas Marine Boundary Layer Reference of the National Oceanic and Atmospheric Administration (NOAA/ESRL)50. According to the guideline, the annual CGR in a given year is the difference in CO2 concentration between the end of December and the start of January of that year.

AbstractGlobal net land carbon uptake or net biome production (NBP) has increased during recent decades1. Whether its temporal variability and autocorrelation have changed during this period, however, remains elusive, even though an increase in both could indicate an increased potential for a destabilized carbon sink2,3.
