Maguire: China will cut electricity emissions to a record low by 2025

China's utilities have been able to achieve record-low emissions in the first half of 2025 by focusing on clean energy supplies.

According to the energy portal, electricitymaps.com, carbon dioxide emissions per Kilowatt Hour (kWh) of Electricity averaged 492 Grams during the first half of 2025.

This was the first time a reading under 500 grams per kWh had been recorded. It is also down from 514g/kWh in the same period of 2024, and 539g/kWh between January and June 2023.

CLEANING UP

The main reason for the reduction of emissions intensity was a nearly 23% increase in clean power production from January to June 2020. This allowed energy firms to reduce the output of coal and gas power stations.

LSEG data shows that the total power generated by thermal power plants – mainly coal – has dropped 4% compared to a year earlier, and is now just below 7,000 terawatt-hours (TWh).

The total output of clean energy from January to the end of June was 2,400 TWh. This shows that fossil fuels still make up 75% of China's electricity generation mix.

The growth of clean energy continues to outpace the growth in fossil fuels, suggesting that China’s power mix is set to continue getting cleaner.

According to LSEG, the total Chinese clean energy output in the first half 2025 will be 200% higher than the first half 2019.

The total thermal power produced in China from January to June of 2025 is 20% higher than the same period last year.

Emissions Toll

China's emissions from the fossil fuel sector have decreased in line with a cleaner mix.

According to data from the energy think tank Ember, total emissions from fossil fuels in electricity production between January and May were 2,24 billion metric tonnes of CO2.

This is 60.5 millions tons less than in the same months of 2020, indicating that Beijing is making progress towards its goals to reduce energy sector pollution.

The lingering economic drag from a property slump and the uncertainty over tariffs imposed by the United States against Chinese goods also impacts China's energy needs and emission totals.

Construction in China has been slowing down sharply in the past decade due to a debt crisis affecting property developers. This has in turn slowed demand for energy-intensive products such as glass, construction steel, cement and piping.

The latest tariffs imposed by U.S. president Donald Trump on Chinese products have impacted the demand for China-made goods and caused production lines to slow down across a variety of manufactured items.

The overall energy needs of these industries have been reduced by the slower pace on construction sites and production lines in factories. This has allowed power generation companies to reduce their production.

China's power requirements will rise if the manufacturing and construction sectors recover. This will lead to a return of fossil fuels that emit pollution.

If China's economy is still slowed by the construction debt and the tariff concerns, then the use of fossil fuels could be further reduced, which would lead to further emissions reductions from the power sector.
