China’s carbon dioxide (CO2) emissions fell by 1% in the second quarter of 2024 in the first quarterly fall since the country re-opened from its “zero-Covid” lockdowns in December 2022.

The new analysis for Carbon Brief, based on official figures and commercial data, shows China remains on track for a decline in annual emissions this year.

Other key findings from the analysis include:

China’s energy demand grew by 4.2% year-on-year in the second quarter of 2024. This is slower than the growth seen in 2023 and in the first quarter of this year, but is still much higher than the pre-Covid trend.

CO2 emissions from energy use and cement production fell by 1% in the second quarter. When combined with a sharp 6.5% increase in January-February and a monthly decline in March, there was a 1.3% rise in CO2 emissions across the first half of the year, compared with the same period in 2023.

Electricity generation from wind and solar grew by 171 terawatt hours (TWh) in the first half of the year, more than the total power output of the UK in the same period of 2023.

China’s carbon intensity – its emissions per unit of GDP – only improved by 5.5%, well short of the 7% needed to meet the country’s intensity target for 2025.

This was despite a one-off boost from China’s hydropower fleet recovering from drought.

Compared with a year earlier, the increase in the number of electric vehicles (EVs) on China’s roads cut demand for transport fuels by approximately 4%.

Manufacturing solar panels, EVs and batteries was only responsible for 1.6% of China’s electricity consumption and 2.9% of its emissions in the first half of 2024.
