- The Global Carbon Budget 2024 is the 19th edition of the annual update that started in 2006 as part of Global Carbon Project, published in the journal Earth System Science Data.
- The Global Carbon Project aims to develop a complete picture of the global carbon cycle, including both its biophysical and human dimensions.
- Global CO2 emissions from fossil use are projected to rise 0.8% in 2024 (range -0.3% to 1.9%) relative to 2023 level.
- Global CO2 emissions from land-use change remain high but they have decreased every decade since the 1990s, and in particular in the past decade (-20%).
- Total CO2 emissions – the sum of fossil and land-use change emissions – have plateaued in the past decade.
- Atmospheric CO2 concentration expected to reach 422.5 ppm in 2024, 52% above pre-industrial levels.
| Absolute Contributors to Global Fossil CO2 (2023 Data) | China: 31% United States: 13% India: 8% EU-27: 7% Collectively account for 59% of global emissions. |
| Sectoral Emissions Growth (2024) | Coal: +0.2% Oil: +0.9% Gas: +2.4% |
