China CO2 Down 1% in First Half of 2025 as Renewables Rise, Chemicals Emerge as Hotspot

The CREA study says early‑2025 renewables growth should keep power‑sector emissions lower into next year.

Overview

  • Power‑sector emissions fell about 3% in January–June, driven by record wind and solar output that outpaced electricity demand growth.
  • Coal burned for power declined 3% in the period, while gas use for electricity generation increased 6%, according to the analysis.
  • Coal use in the chemicals industry rose about 20% in the first half, making the sector the main source of upward pressure on national emissions.
  • The coal‑to‑chemicals buildout has added roughly 3% to China’s emissions since 2020 and could add about 2% more by 2029, the report estimates.
  • A weak property sector pulled down emissions from cement, steel and other building materials, partially offsetting increases in chemicals, and a June 1 policy change slowed new wind and solar installations after strong early‑year gains.
