The Yangtze River Delta region has always had a developed economy and active traffic, which has resulted in an extremely high number of motor vehicles and serious air pollution problems. Since January last year, China’s Yangtze River Delta region has suffered from smog, with a pollution area of ​​1.3 million square kilometers. To this end, the two provinces and one city in the Yangtze River Delta intend to coordinate the supervision of the yellow-label vehicles, share the "blacklist", and unite the heart.

According to statistics, as of the end of 2013, the number of motor vehicles in the two provinces and one city in the Yangtze River Delta has reached 34 million, accounting for 14% of the total vehicle ownership in the country. The number is still growing at 23%. The huge quantity and growth rate of motor vehicles have further compressed the atmospheric environment capacity of this region, and strengthening the environmental management of vehicles in use has become the key to reducing emissions and effective treatment of motor vehicles in the Yangtze River Delta region.
How big is the impact of such a large number of motor vehicles on the atmosphere? Last year, there were 24 over-standard PM2.5 in 25 cities of the Yangtze River Delta. According to data released by the China Meteorological Administration, the fog and haze days in the central and southern parts of North China to the northern part of the south of the Yangtze River range from 50 days to 100 days, and in some areas over 100 days.
Grasping the focus of motor vehicle emission reduction, eliminating the yellow standard car According to the calculation of the environmental protection department of Nanjing City, the pollution caused by the exhaust gas of a yellow standard vehicle is equal to 28 national IV standard vehicles, which is a pollution “masterâ€.
What is the proportion of yellow-label vehicles in the total number of motor vehicles? According to relevant data, the yellow-label vehicles in the two provinces and one city in 2012 accounted for about 16% of the total number of vehicles, and their nitrogen oxides accounted for more than half of all motor vehicle emissions. This figure fully shows that in order to reduce vehicle emissions, the elimination of yellow-label vehicles is the focus and key.
As of the first half of 2014, Jiangsu, Zhejiang and Shanghai respectively eliminated 80,000, 80,000 and 60,000 yellow-label vehicles and old vehicles. It is required to phase out 307,000, 281,000 and 160,000 vehicles respectively in 2014. There is still a big gap in requirements.
It is difficult to supervise in different places. Why is it difficult to manage the "blacklist" sharing system? One of the most important reasons is the frequent interaction of vehicles in neighboring provinces and cities, which makes it difficult to supervise in different places.
Take Shanghai as an example. In 2012, the average daily traffic volume of Shanghai's external road vehicles reached 346,000, an increase of 47% in the past five years. Among them, the direction to Jiangsu and Zhejiang increased by 51% and 41% respectively. How to speed up the elimination of yellow-label cars and old cars in different cities through remote management is a difficult problem to be solved.
The "blacklist" sharing system was put on the table. It is reported that the two provinces and one city in the Yangtze River Delta intend to establish a "black list" of motor vehicles, including the basic information of the yellow label vehicles in each city, forming a mechanism for sharing and regularly updating the regional blacklists of motor vehicles. After the yellow label vehicles are eliminated, Gradually extend the “blacklist†to other highly polluting models.
