In which year did the National IV emission standards begin to be implemented?
1 Answers
National IV emission standards began to be implemented on July 1, 2010, and were fully implemented nationwide until July 1, 2017, when National V standards took over. Therefore, cars produced between 2011 and 2017 were generally compliant with National IV emission standards. However, this is not entirely accurate, as the timing of emission standard implementation varied across different regions in the country. How many more years can National IV vehicles be driven? 1. Implementation of National V emission standards: Based on past experience, when National V standards were implemented, National II vehicles were phased out (i.e., forced to be scrapped). Therefore, when National VI standards are implemented, National III vehicles are likely to be phased out as well, while National IV vehicles will not be phased out until after National VII standards are implemented. The timeline for the introduction and implementation of National VII standards is unknown, but it is certain that it will be a long time from now. 2. National VI standards are very strict: After all, National VI standards have just begun to be implemented and are not yet fully enforced nationwide. Moreover, the current National VI standards are already the strictest emission standards globally, so the introduction and implementation of National VII standards will undoubtedly take a very long time. Therefore, National IV vehicles should be able to be used until their normal retirement without worrying about being forced to be scrapped due to the implementation of emission standards.
