For the first time, the growth in China’s clean power generation has caused the nation’s carbon dioxide (CO2) emissions to fall despite rapid power demand growth.
China’s emissions were down 1.6% year-on-year in the first quarter of 2025 and by 1% in the latest 12 months.
Electricity supply from new wind, solar and nuclear capacity was enough to cut coal-power output even as demand surged, whereas previous falls were due to weak growth.
The analysis, based on official figures and commercial data, shows that China’s CO2 emissions have now been stable, or falling, for more than a year.
However, they remain only 1% below the latest peak, implying that any short-term jump could cause China’s CO2 emissions to rise to a new record.
Other key findings include:
- Growth in clean power generation has now overtaken the current and long-term average growth in electricity demand, pushing down fossil fuel use.
- Power-sector emissions fell 2% year-on-year in the 12 months to March 2025.
- If this pattern is sustained, then it would herald a peak and sustained decline in China’s power-sector emissions.
- The trade “war” initiated by US president Donald Trump has prompted renewed efforts to shift China’s economy towards domestic consumption, rather than exports.
- A new pricing policy for renewables has caused a rush to install before it takes effect.
- There is a growing gap that would need to be bridged if China is to meet the 2030 emissions targets it pledged under the Paris Agreement.
If sustained, the drop in power-sector CO2 as a result of clean-energy growth could presage the sort of structural decline in emissions anticipated in previous analysis for Carbon Brief.
The trend of falling power-sector emissions is likely to continue in 2025.
However, the outlook beyond that depends strongly on the clean energy and emissions targets set in China’s next five-year plan, due to be published next year, as well as the economic policy response to the Trump administration’s hostile trade policy.
