The Industrial Policy Department of the Ministry of Industry and Information Technology issued the "Announcement No. 27 of the Ministry of Industry and Information Technology of the People's Republic of China" that it is scheduled to abolish the diesel vehicle products applicable to the national third-stage automobile emission standard (hereinafter referred to as "National Three") on December 31, 2014. "Announcement", the national diesel vehicle products will not be sold from January 1, 2015.
In other words, the Ministry of Industry and Information Technology will fully implement the national four emission standards from January 1 next year. The approval of the new car announcement catalogue for the national three emission standards will be completed by the end of this year, and the sales of the national third emission standard vehicles will also be until the end of this year.
The Ministry of Industry and Information Technology’s statement will delay the delay of the national four emission standards. The two delays in the national four emission standards were basically due to the disagreement between the Ministry of Industry and Information Technology and the Ministry of Environmental Protection. The Ministry of Industry and Information Technology had previously worried about the quality of China's diesel oil products.
However, the current government can no longer endure the environmental pressure of smog across the country. In the government work report, Premier Li Keqiang clearly pointed out that in 2014, the country will supply four standard diesel vehicles in the country. This specific report content has never been seen before, and it has also released the signal of “no need for environmental protection standards”, which has accelerated all localities. The process of implementing the four national standards.
In fact, the national four emission standards were originally planned to be implemented on January 1, 2011, but on December 21, 2010, the environmental protection department stated that the implementation time of the diesel four national standard of 3.5 tons or more was postponed for one year, that is, until January 1, 2012. Implemented on the day. However, due to the quality of diesel products and other reasons, the national four standards were postponed again, and officially implemented on July 1, 2013. However, on the eve of the implementation, the Ministry of Environmental Protection reached an agreement with the Ministry of Industry and Information Technology and the Automobile Industry Association on the implementation time of the State IV. The national four-emission standard for heavy-duty diesel vehicles, which was originally scheduled to be implemented on July 1, 2013, was postponed again.
