Beijing, Jan. 4 (Xinhua): Beijing saw more days with good air quality and a density of PM2.5 record average, the distance from the municipal environment.

The average concentration of PM2.5 in the Metropolis was 38 micrograms per cubic meter by 2020, a year-on-year decrease of 9.5 percent and the lowest measurement from the measure. The data was collected for the first time in 2013, according to the Municipal Ecology of Beijing and the Office of Environment.

However, experts say that the Beijing-Tianjin-Hebei region and nearby areas face an arduous task to further improve air quality as the region . The emissions of air pollutants still exceed their environmental capacity.

The authorities in Beijing have promised to advance regional cooperation on the control of air pollution and further reduce carbon dioxide emissions and other pollutants. such as PM2.5, ozone," target="_BLANK">volatile organic compounds and nitrogen oxides by 2021. enditem
