From January to August, Beijing's average concentration of fine particulate matter (PM2.5) was 25.6 micrograms per cubic meter, down 17.2 percent year on year. The number of days with good or excellent air quality reached 198, 20 days more than in the same period last year. In August, the monthly average PM2.5 level was 16.7 micrograms per cubic meter.

Beijing implemented policies such as vehicle trade-ins and the scrapping and replacement of old trucks and medium-to-large buses meeting National IV and lower emission standards. More than 5,000 old commercial and passenger vehicles applied for the Beijing Vehicle Trade-in Replacement Subsidy to switch from petrol to new energy vehicles. Through financial incentives and pilot projects in key sectors, the city has promoted the use of new energy vehicles in areas such as urban logistics and supermarkets. The number of new energy vehicles in Beijing has now surpassed 1.16 million.

Districts across the city have made efforts to accelerate the "green transformation" of enterprises. From January to August, 832 new green enterprises were established, raising their share to 32 percent and beating the annual target ahead of schedule. Additionally, 699 boiler-using units completed environmental performance ratings, exceeding the annual goal and further reducing nitrogen oxide emissions.

To tackle the summer spike in volatile organic compounds (VOCs), Beijing launched special campaigns focusing on critical periods and strengthening daily precise enforcement and supervision. These efforts ensured emissions from various pollution sources remained stable and compliant, continuously lowering baseline pollution levels.

Going forward, Beijing will continue to drive the "green transformation" in three major areas — structural adjustments, engineering projects, and management — in a bid to secure lasting improvements in air quality.
