In which year did the National IV emission standards begin to be implemented?

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.
I remember the China IV emission standards were nationally enforced starting in 2013. From July 1st that year, all newly sold vehicles had to meet this standard. Prior to that, China IV was piloted in major cities like Beijing and Shanghai as early as 2011, aiming to reduce vehicle exhaust pollution, especially PM2.5 and nitrogen oxides. As someone who's driven for many years, I've personally witnessed the noticeable improvement in urban air quality after implementation. Manufacturers upgraded catalytic converters and OBD systems with more advanced technology. This also impacted the used car market - China III compliant vehicles depreciated significantly overnight. Looking back now, this standard was an environmental milestone that paved the way for subsequent China V and China VI standards, giving us greater peace of mind in our daily commutes.
The China IV emission standard was officially implemented nationwide in July 2013. When the policy was first introduced, I followed the news about how the country was tackling the smog crisis by mandating emission reductions for new vehicles. I remember that light-duty vehicles had to meet the standard before they could be sold. This also drove fuel upgrades, reducing sulfur content in gasoline, making refueling more stable. In car enthusiast groups, I heard discussions about how both domestic and imported vehicles were affected. In fact, major cities had already trialed China IV a few years earlier, but nationwide unification came in 2013. Since then, every vehicle leaving the factory carried a China IV label, making it easier for people to choose eco-friendly cars. The government also provided subsidies to encourage vehicle replacements, reducing the number of older cars on the road, leading to noticeable environmental improvements.
