Global Carbon Budget 2023

Global carbon emissions from fossil fuels have risen again in 2023 – reaching record levels. The annual Global Carbon Budget projects fossil carbon dioxide (CO2) emissions of 36.8 billion tonnes in 2023, up 1.1% from 2022. Fossil CO2 emissions are falling in some regions, including Europe and the USA, but rising overall – and the scientists say global action to cut fossil fuels is not happening fast enough to prevent dangerous climate change. Emissions from land-use change (such as deforestation) are projected to decrease slightly but are still too high to be offset by current levels of reforestation and afforestation (new forests). The report projects that total global CO2 emissions (fossil + land use change) will be 40.9 billion tonnes in 2023. This is about the same as 2022 levels, and part of a 10-year “plateau” – far from the steep reduction in emissions that is urgently needed to meet global climate targets.
