China will carry out three major actions to improve air quality.
Xinhua News Agency reporter Gao Jing
The Ministry of Ecology and Environment and other departments 15 jointly issued the "Action Plan for Deepening the Elimination of Heavy Pollution Weather, Ozone Pollution Prevention and Control and Diesel Truck Pollution Control", proposing that by 2025, the country's heavily polluted weather and above will be basically eliminated; The coordinated control of PM2.5 and ozone has achieved positive results, and the growth trend of ozone concentration has been effectively curbed; The pollution control level of diesel trucks has been significantly improved, and the total discharge of major pollutants from mobile sources has decreased significantly.
The relevant person in charge of the Department of Atmospheric Environment of the Ministry of Ecology and Environment said that in recent years, China's ambient air quality has improved significantly. However, the situation of air pollution control is still grim. Heavy pollution weather in Beijing, Tianjin and Hebei and surrounding areas is still frequent in autumn and winter, and more than half of the cities in China still have heavy pollution weather. Ozone pollution has become increasingly prominent, especially in summer, which has become the primary factor leading to air quality exceeding the standard in some cities. The pollution of diesel trucks has not been effectively solved. The emission of nitrogen oxides from mobile sources accounts for about 60% of the total emission of nitrogen oxides in China, which contributes greatly to PM2.5 and ozone pollution.
According to reports, the battle to eliminate heavy pollution weather focuses on PM2.5 pollution, autumn and winter (10 to March of the following year), Beijing-Tianjin-Hebei and its surrounding areas with frequent heavy pollution weather, Wei Fen Plain, Northeast China and urban agglomerations on the northern slope of Tianshan Mountain with relatively weak prevention and control of heavy pollution weather, and puts forward corresponding measures according to different regional pollution characteristics. According to the action plan, by 2025, severe and above polluted weather will be basically eliminated, and the proportion of severe and above polluted days in the country will be controlled within 1%. More than 70% cities at prefecture level and above have completely eliminated severe and above polluted weather, and the number of days caused by human factors in Beijing-Tianjin-Hebei and surrounding areas, Wei Fen Plain, Northeast China and the northern slope of Tianshan Mountain has been reduced by more than 30%.
The battle against ozone pollution will be concentrated from May to September, with Beijing-Tianjin-Hebei and its surrounding areas, the Yangtze River Delta region and the Wei Fen Plain as the key areas for ozone pollution prevention and control in China. Cities with ozone exceeding the standard, such as the Pearl River Delta region, Chengdu-Chongqing region, and urban agglomerations in the middle reaches of the Yangtze River, will carry out tough battles under the guidance of the state, increase the emission reduction of volatile organic compounds (VOCs) and nitrogen oxides, enhance their capabilities, and fill the shortcomings. The Action Plan proposes that by 2025, the coordinated control of PM2.5 and ozone will achieve positive results, and the growth trend of ozone concentration in the country will be effectively curbed. The total emission of VOCs and nitrogen oxides decreased by more than 10% compared with 2020.
The battle for pollution control of diesel trucks will focus on Beijing-Tianjin-Hebei and its surrounding areas, the Yangtze River Delta region, the relevant provinces (cities) in Wei Fen Plain and the central and western cities of Inner Mongolia Autonomous Region, promote the adjustment of transportation structure and the cleaning of vehicles and boats, strengthen the supervision of diesel trucks and off-road mobile machinery, and strengthen the coordinated prevention and control of departments and regions. According to the Action Plan, by 2025, the cleanliness and low-carbon degree of transportation structure and vehicle and boat structure will be significantly improved, and the fuel quality will continue to improve. The phenomenon that motor vehicles and boats, construction machinery and railway diesel locomotives in key areas emit excessive black smoke will be basically eliminated. The national diesel vehicle emission test pass rate will exceed 90%, the national diesel vehicle emission will drop by 12%, and the proportion of new energy and national six emission standard trucks will strive to exceed 40%, and the railway freight volume will be increased.
The person in charge said that it is necessary to take the completion of the annual and final targets of the landmark campaign as an important part of in-depth assessment of the effectiveness of the battle against pollution. Strengthen the implementation of objectives and tasks. For areas that have not completed their objectives and tasks, informed criticism will be implemented in accordance with the law and regulations, and the relevant implementation will be included in the central ecological environmental protection inspector.
