Four measures to promote the prevention and control of air pollution and defend the blue sky.

Four measures to promote the prevention and control of air pollution and defend the blue sky.

Since the beginning of this year, China has faced the dual pressures of relatively unfavorable meteorological conditions and obvious increase in pollution emissions, and the situation of improving air quality has become more severe. We will defend the blue sky through four major measures.

From the end of last year to the beginning of this year, Hebei, Shandong, Henan, Shanxi, Shaanxi and other provinces experienced 1 1 day, which is rare in recent years. This year, the national average concentration of PM2.5 increased by 6.7%, the average concentration of PM 10 increased by 23.9%, and the proportion of excellent days decreased by 2.4 percentage points.

Since the beginning of this year, China's economic and social activities and production and living order have accelerated, and the incremental pressure of pollutant discharge is greater. In addition, since the beginning of this year, the national temperature has been relatively high year-on-year, and the number of precipitation days and daily precipitation has been relatively small year-on-year, which is not conducive to the diffusion and removal of pollutants. All these indicate that the effectiveness of air quality improvement in China is still not stable, and the long-term, complex and arduous nature of air pollution prevention and control still exists.

This year, the Ministry of Ecology and Environment will take four major measures to prevent and control air pollution. We will comprehensively promote various tasks and measures for the prevention and control of heavy polluted weather, ozone pollution and diesel truck pollution, promote clean heating in the northern region according to local conditions, and steadily promote the clean-up of loose coal in key areas and plain areas. Strengthen regional joint prevention and control and heavy pollution weather response, strengthen supervision and law enforcement of air pollution prevention and control, help enterprises improve pollution control facilities, and promote the continuous improvement of air quality throughout the country.
