China's carbon emissions fell in the first half of 2025, study shows

China's carbon emissions fell 1% in the first half of 2025, primarily due to a 3% reduction in the power sector driven by increased renewable energy adoption, particularly solar, and a weak property sector impacting emissions from building materials and metals. This decline positions the world's largest emitter for a potential full-year reduction, aligning with its 2030 peak and 2060 net-zero targets. However, emissions from the chemicals industry continue to rise, fueled by a 20% increase in coal-to-chemicals production, presenting a notable counter-trend risk to overall decarbonization efforts.

Analysis

China's carbon dioxide emissions declined 1% year-over-year in the first half of 2025, a development primarily driven by a 3% drop in emissions from the power sector. This reduction is directly attributed to the accelerated adoption of renewable energy, particularly solar, where capacity is projected to hit record additions for the year. Consequently, coal consumption in the power sector fell by 3%, although gas-fired power generation increased by 6%. A secondary factor contributing to the overall emissions decrease was the persistent weakness in China's property sector, which suppressed output and related emissions from building materials, metals, cement, and steel industries. However, this positive trend is partially offset by a significant counter-narrative in the chemicals industry, where emissions are rising. The use of coal as a feedstock for synthetic fuels and petrochemicals surged by 20% in H1 2025, a trend that has reportedly added 3% to China's total carbon emissions since 2020 and presents a material risk to its long-term decarbonization goals.

Key Decisions for Investors

• Consider long positions in China's solar energy value chain, as its rapid expansion is the primary structural driver of the power sector's emissions decline.
• Adopt a cautious stance on Chinese industrial commodities like steel and cement, whose demand is suppressed by the weak property sector, while noting the specific growth in demand for natural gas in power generation and coal in chemical production.
• Investors with ESG mandates should scrutinize exposure to China's coal-to-chemicals industry, as its 20% growth in feedstock consumption represents a significant and growing risk that runs counter to the country's broader climate targets.
• Differentiate between the cyclical drivers of emissions reduction, such as the property downturn, and the structural shift to renewables to accurately assess the durability of this decarbonization trend.
