Progress of major emitters towards climate targets: 2025 Update

Assuming full implementation of existing policies, our current policies scenario projects a reduction in emissions by 2035 in its lower projection, whereas it results in a 'plateauing' of the emission trajectory in its higher projection.The upper end of the projected emissions range shows a growth of 0.1% per year between 2021 and 2035, while the lower end projects a decrease of 1% per year.Tab. 1 Key metrics of our 2025 report update Data refers to aggregated emissions and considers the 25 countries analysed Comparison metric 2024 report 2025 report 2025 aggregated emissions 37.9 to 41.4 GtCO2e* 38.8 to 40.2 GtCO2e 2030 aggregated emissions 34.7 to 40.4 GtCO2e* 36.3 to 40.1 GtCO2e 2035 aggregated emissions -32.8 to 39.1 GtCO2e Change between 2015 and 2035 --14% to +3% Change between 2019 and 2035 --15% to +1% * Corrected for GWP AR6.
