The rapid growth of motor vehicle possession has become a major culprit in air pollution. Chen Jining, minister of the Ministry of Environmental Protection, said on the evening of 6th that many large and medium-sized cities have high emissions of motor vehicle pollutants and have become the primary source of fine particulate matter.
At the air pollution prevention media meeting held by the Ministry of Environmental Protection on the evening of the 6th, Chen Jining provided a set of data: In 2016, the national motor vehicle ownership reached 300 million, including 190 million vehicles. 31.3% in Beijing, 29.2% in Shanghai, and 28% in Hangzhou are all from motor vehicles.
In the areas around Beijing and Tianjin, where the smog is most serious, Beijing, Tianjin, Hebei, Shanxi, Shandong, and Henan provinces, the land area only accounts for 7.2% of the country's total, and the proportion of motor vehicles is as high as 28%.
Chen Jining said that an old car is equivalent to 20 to 40 vehicles discharged from the National IV and National V standards. The heavy-duty diesel vehicle is equivalent to 200 vehicles, and many of them are not up to standard. Therefore, it is necessary to speed up the elimination of old cars, increase supervision over heavy polluting vehicles, and gradually propose new vehicle emission standards, while strengthening oil product control.
Chen Jining specifically pointed out the problem in Beijing. “Beijing’s pollution structure is different from that of other regions. The core issue is to solve the problem of heavy pollution vehicles.†He said, “Encourage environmentally friendly green cars to travel, especially to encourage public transportation. If Beijing does not solve the problem of vehicles, Especially for the problem of heavily polluting vehicles, it is more difficult to improve air quality."
He said that the next step will encourage qualified regions to implement new emission standards in advance, strengthen the environmental protection compliance of new production vehicles, and speed up the networking of national, provincial and municipal motor vehicle sewage monitoring platforms, especially for heavy-duty diesel vehicles. Supervised management of high-emission vehicles; implementation of clean diesel operations to promote oil product upgrades.
