Global CO emissions 2 in 2024 they increased by 0.9 % compared to the previous year and reached 36.3 Gt CO 2 These ongoing emissions are further depleting remaining carbon budgets, with some estimates suggesting that the 1.5°C budget will be exceeded within the next 5 years – and may already have been.
Key points
- Global emissions averaged 99.3 Mt CO 2 per day, with the largest increase coming from India and Russia and a slight decrease from China.
- Global non-fossil energy development increased by 6.2 %, corresponding to estimated emissions of 9.8 Gt CO 2 in the range of 4 (i.e. eliminated) in 2024.
- 0 – 205 Gt CO 2 remains from the carbon budget to limit warming to 1.5°C, indicating that permitted emissions have already been exceeded or could be exhausted within 5.1 years; 860–955 Gt CO2 remains from the 2°C budget, which could be exhausted within 21.3–23.7 years (with a probability of 67 %).
