In the first half of 2025, China's carbon dioxide emissions decreased by 1%, primarily due to an increase in renewable energy use. The power sector saw a 3% drop in emissions, while coal-to-chemicals growth contributes to rising emissions in the chemicals industry.
China has reported a notable decrease in carbon dioxide emissions, achieving a 1% reduction in the first half of 2025 compared to the same period last year. The drop is largely attributed to an increase in renewable energy utilization, helping mitigate the environmental impact from the country's prominent power sector, which saw emissions decrease by 3%, according to a study by the Centre for Research on Energy and Clean Air.
CREA's lead analyst, Lauri Myllyvirta, highlighted the remarkable growth in solar power capacity. This trend indicates potential for a full-year decline in emissions, setting a promising precedent as China works towards its long-term environmental goals of peaking emissions by 2030 and achieving net-zero by 2060. However, coal remains a concerning factor as its usage in the chemicals industry grows.
While reductions have been observed across various sectors including building materials and metals, emissions in China's chemicals industry continue to rise, driven by increased coal use for synthetic fuels and petrochemical production. The study shows this has contributed to a 3% increase in overall emissions since 2020, highlighting an area that could hinder broader environmental progress.
