Core Viewpoint - In 2025, Beijing achieved significant improvements in air quality, with PM2.5 annual average concentration dropping to 27.0 micrograms per cubic meter, marking a historic low and a milestone in air pollution control efforts [2][4]. Group 1: Air Quality Improvements - The annual average concentration of PM2.5 in Beijing reached 27.0 micrograms per cubic meter in 2025, a year-on-year decrease of 11.5%, marking the first time it fell below 30 micrograms [2][4]. - Other major pollutants also saw improvements, with PM10, NO2, and O3 concentrations at 48, 22, and 159 micrograms per cubic meter respectively, showing year-on-year declines of 11.1%, 8.3%, and 7.0% [2][4]. - The number of days with good air quality reached 311 in 2025, an increase of 21 days from the previous year, resulting in a good air quality rate of 85.2%, the highest since monitoring began [4][10]. Group 2: Long-term Trends - Since 2013, PM2.5 levels in Beijing have shown a consistent downward trend, decreasing from 89.5 micrograms per cubic meter to 27.0 micrograms per cubic meter, a reduction of 69.8% [6][8]. - Heavy pollution days dropped dramatically from 58 days in 2013 to just 1 day in 2025, a reduction of 98.3% [8][10]. Group 3: Policy and Management Initiatives - Beijing's air quality improvements are attributed to comprehensive pollution control measures, including the promotion of new energy vehicles, with over 60% of new cars being electric by 2025 [12][13]. - The city implemented a range of green initiatives, including the creation of 1,803 "green" enterprises, representing 39.7% of the total, and the establishment of a robust regulatory framework for pollution control [12][14]. - Collaborative efforts with neighboring regions, such as Tianjin and Hebei, have enhanced air quality through joint pollution control strategies [15].
