Summary
A new health impact assessment shows that China's tightened annual fine particulate matter (PM2.5) standard could substantially reduce premature deaths and move the country closer to the World Health Organization (WHO) 2040 goal of halving air-pollution-related mortality. The study estimates PM2.5-attributable mortality in mainland China from 2013 to 2024 and compares full compliance with annual limits of 35, 30 and 25 micrograms per cubic meter ((micro)g m⁻³). It finds that the 25 (micro)g m⁻³ limit would avert about 4.3 times as many deaths as the former 35 (micro)g m⁻³ limit in 2024 and could achieve roughly 83% of the PM2.5-specific progress needed for the WHO halving target, while benefits vary widely by disease.
