Officials from the Ministry of Ecology and Environment said to reporters in Beijing on the 2nd that they will speed up the formulation of a campaign plan for the implementation of the pollution control of diesel trucks, and establish an environmental supervision system that implements the most stringent motor vehicle “full prevention and control†to promote the environmental quality of urban and regional environments. improve.
The "China Motor Vehicle Environmental Management Annual Report (2018)" released by the Ministry of Ecology and Environment shows that China has become the world's largest motor vehicle production and sales country for nine consecutive years. In 2017, the number of motor vehicles in the country reached 310 million. Motor vehicle pollution has become an important source of air pollution in China, and the urgency of motor vehicle pollution prevention and control has become increasingly prominent.
The person in charge of the Department of Atmospheric Environment Management of the Ministry of Ecology and Environment said that with the rapid increase in the number of motor vehicles, the air in some cities in China began to show the characteristics of combined pollution of coal smoke and motor vehicle exhaust, which directly affected people's health.
In 2017, the total amount of four pollutants discharged by motor vehicles nationwide was initially calculated as 43.597 million tons, a decrease of 2.5% over the previous year. Among them, carbon monoxide (CO) was 33.273 million tons, hydrocarbon (HC) was 4.071 million tons, nitrogen oxides (NOx) was 5.743 million tons, and particulate matter (PM) was 509,000 tons. Cars are the main contributors to motor vehicle emissions. Diesel trucks, which account for 7.8% of car ownership, emit 57.3% of NOx and 77.8% of PM, which is the top priority of motor vehicle pollution prevention.
The person in charge of the Department of Atmospheric Environment Management said that the Ministry of Ecology and Environment will speed up the formulation and implementation of the campaign plan for the pollution control of diesel trucks, reduce the total amount of diesel vehicle pollution emissions, optimize and adjust the transportation structure, and focus on high-pollution and high-emission diesel trucks. Strict motor vehicle "full defense full control" environmental supervision system, the implementation of clean diesel vehicles, clean diesel engines, clean transportation and clean oil products four actions to ensure a significant increase in the proportion of railway freight, the total discharge of pollutants significantly reduced, promote the city and Regional ambient air quality has improved significantly.
