Beijing has made remarkable strides in improving its air quality in 2025, with the Beijing Municipal Ecology and Environment Bureau reporting a 16.6% reduction in the average PM2.5 concentration during the first ten months of the year. The average concentration of fine particulate matter (PM2.5) from January to October stood at 25.6 micrograms per cubic meter, marking a significant improvement. Additionally, the city recorded 254 days of good air quality, an increase of 20 days compared to the same period in 2024. These achievements are attributed to systematic efforts, including the promotion of new energy vehicles, which have surpassed 1.2 million in number by October. To address seasonal pollution, Beijing has strengthened regional collaboration and employed advanced technologies such as satellite remote sensing and online monitoring to identify and mitigate high-pollution areas. These measures underscore the city’s commitment to combating air pollution and enhancing environmental sustainability.
