LITTLETON, Colorado: Surging clean power supplies have allowed China's utilities to reduce their emissions from electricity production to record lows during the opening half of 2025.
Carbon dioxide emissions per kilowatt hour (kWh) of electricity averaged 492 grammes during the opening half of 2025, according to data from energy portal electricitymaps.com.
That was the first ever reading below 500 grammes per kWh, and is down from 514g/kWh during the same period in 2024 and 539g/kWh from January to June 2023.
A nearly 23% rise in clean power generation from January to June 2024 was the main driver behind the reduction in emissions intensity, as higher volumes of clean energy allowed power firms to reduce output from coal and gas power plants.
Total power generation from thermal power plants — mainly coal — dropped by 4% from a year ago to just under 7,000 terawatt hours (TWh), data from LSEG shows.
Output from clean energy sources from January to June totalled 2,400 TWh, highlighting that fossil fuel power sources still account for a 75% share of China's power generation mix.
But the growth of clean energy supplies continues to sharply outpace growth in fossil fuel power generation, suggesting that China's power mix looks set to keep getting cleaner.
Total Chinese clean power output during the first half of 2025 was 200% more than during the first half of 2019, according to LSEG.
In contrast, total Chinese thermal power output from January to June 2025 was 20% greater than during the same period in 2019.
China's power sector emissions from fossil fuel generation have declined in line with the cleaner mix.
Total emissions from fossil fuels used in electricity production from January to May were 2.24 billion metric tonnes of CO2, according to data from energy think tank Ember.
That total is 60.5 million tonnes less than during the same months of 2024, and is an indication that some progress is being made against Beijing's goals of reducing energy sector pollution.
However, the enduring economic drag caused by a lingering property downturn as well as the uncertainty surrounding tariffs charged by the United States on Chinese goods is also impacting China's power needs and emissions totals.
The pace of construction in China has slowed sharply so far this decade following a debt crisis among property developers, which in turn has choked off demand for energy-intensive goods such as cement, piping, glass and construction steel.
More recently, the fresh tariffs on Chinese goods set by US President Donald Trump this year have hit demand for China-made products, and slowed production lines across several manufactured items. — Reuters
