The city's environment regulator said that the cumulative concentration of PM2.5 in Beijing has fallen to 39 micrograms per cubic meter of air between January to November of 2020, a decrease of 7.1% year on year.

The PM2.5 density in Beijing has measured approximately 30 micrograms per cubic meter for three consecutive months since September, which ranks Beijing's air the best among 28 cities in the Beijing-Tianjin-Hebei region.

Statistics also show that Beijing had 245 good air days in the first 11 months of 2020, an increase of 30 days over the same period last year.

Beijing carried out an air pollution treatment campaign last month to address key issues concerning the treatment of heavy-duty vehicles, volatile organic compounds (VOCs), dust, and the emergency response to pollutants. The project has provided references for the city's treatment efforts during the upcoming 14th Five-Year Plan period.

Regarding vehicle emissions control, Beijing has removed over 52,000 petrol-fueled vehicles from its roads, and 401,000 new energy vehicles have been introduced in the city. Over 90% of Beijing's buses are now powered by renewable energy.

Beijing has also worked to eliminate VOCs at the source. Starting Dec. 1, the city plans to strictly implement national policies that limit the amount of VOCs contained in adhesives, cleaning agents, and coatings.

In addition, the city has established a video monitoring platform to help control the level of dust found at construction sites. The platform has now reached over 2,600 construction sites, with five having been disqualified to bid for projects in Beijing for one to five months on account of severe dust problems. The dust level in Beijing has thus remained the lowest found among the nearby 28 cities in September and October.

Beijing has created an ecological protection law enforcement team to tackle VOC emissions of industrial companies, auto repair shops, and restaurants. Between January to November, they reported 4,045 stationary source environmental violations.
