China’s carbon dioxide (CO2) emissions stayed at, or just below, last year’s levels in the third quarter of 2024, after a fall in the second quarter.
Lauri Myllyvirta’s analysis for Carbon Brief, based on official figures and commercial data, leaves open the possibility that China’s emissions could fall this year.
However, recent record-high temperatures caused emissions to go up in September and new government stimulus measures mean there is now greater uncertainty over the country’s emissions trajectory.
Heatwaves through much of August and September caused a major increase in electricity demand for air conditioning, which, combined with weak hydropower output, meant a 2% increase in coal-fired power generation and a 13% rise for gas-fired power in the third quarter, despite wind and solar growth continuing to break records.
The increase in emissions in the power sector was offset by falling emissions from steel, cement and oil use, plus stagnating gas demand outside the power sector, meaning China’s CO2 output in the third quarter was flat or slightly declined, relative to a year earlier.
Other key findings from the analysis include:
- Solar generation rose 44% in the third quarter of the year and wind by 24%, with both continuing to see record-breaking additions of new capacity.
- Hydro generation was up 11% compared with last year’s drought-affected figures, but remained short of expected output. Nuclear power was up 4%.
- Oil demand fell by around 2%, due to falling construction activity, the rise of electric vehicles (EVs) and natural gas (LNG) trucks, as well as weak consumer spending.
- Emissions from steel fell by 3% and cement by 12% in the third quarter, as both sectors continued to see the effect of falling construction activity.
- The coal-to-chemicals industry received renewed political backing and coal consumption in the sector has risen by nearly a fifth in the year to date.
