CO2 emissions fell year-on-year in almost all major sectors in 2025, including transport (3%), power (1.5%) and building materials (7%).
Solar power output increased by 43% year-on-year, wind by 14% and nuclear 8%, helping push down coal generation by 1.9%.
Energy storage capacity grew by a record 75 gigawatts (GW), well ahead of the rise in peak demand of 55GW.
This means that growth in energy storage capacity and clean-power output topped the increases in peak and total electricity demand, respectively.
The latest analysis shows China’s CO2 emissions have now been flat or falling for 21 months, starting in March 2024.
Power sector emissions fell by 1.5% year-on-year in 2025, with coal use falling 1.7% and gas use increasing 6%.
Emissions from transportation fell 3% and from the production of cement and other building materials by 7%, while emissions from the metal industry fell 3%. »
