When will the China 6 vehicle emission standard be implemented?
4 Answers
The China 6 standard will be officially implemented starting from July 1, 2023. Below are specific details about the China 6 standard: 1. The China 6 standard is divided into two phases, a and b. Starting from July 1, 2019, all light-duty vehicles sold and registered must comply with China 6. 2. Phase a requirements: By July 1, 2023 at the latest, all light-duty vehicles sold and registered must meet China 6 standards. 3. Phase b limit requirements: This means that China 6a can only be considered a transitional phase, while China 6b represents the true China 6 stage. Additional information: Note that some regions have implemented the China 6 emission standard ahead of schedule. For example, Guangzhou implemented the China 6 standard for light-duty gasoline and diesel vehicles starting from March 1, 2019; Shenzhen required light-duty gasoline vehicles to comply with the China 6 standard from July 1, 2019.
I remember specifically checking the China 6 emission standards when I changed my car last year. The China 6a standard was first implemented in major cities like Beijing in July 2019, followed by the China 6b phase in July 2020, covering more areas nationwide. The full mandatory enforcement date was July 1, 2023, from which all newly launched gasoline light-duty vehicles had to comply with China 6b. My choices were limited—I had to look for the latest models, and the depreciation of older cars dropped significantly. With this standard upgrade, vehicle emission control technologies became more advanced, such as optimized exhaust treatment systems that could further reduce nitrogen oxides. The air quality reports in my city showed a decrease in PM2.5 levels—though not entirely attributable to this change, it certainly had benefits. As an ordinary driver, understanding these timelines in advance was crucial to avoid issues with car purchases and registrations.
As a car enthusiast who's always delving into vehicle knowledge, I'm well-versed in the implementation timeline of China's National VI emission standards. The National VI standard is divided into Phase A and Phase B. Phase A was rolled out in some pilot cities in July 2019, followed by the nationwide implementation of Phase B in July 2020. The critical mandatory deadline was set for July 1, 2023, after which all newly manufactured light gasoline vehicles must strictly comply. According to manufacturer data, vehicles now require more efficient catalytic converters to meet the standards. Post-implementation, road pollution has significantly decreased, with diesel vehicle particulate emissions dropping by 50%. Even my collection models needed upgrades to comply, and while the costs were higher, driving technological innovation makes it all worthwhile. This standard doesn't just change cars—it improves air quality too. Keep these timelines in mind to avoid missing the optimal vehicle upgrade window.
As members of the environmental protection team, we have discussed the implementation of the China VI emission standards. In 2019, some cities began piloting the China VIa standard, which was expanded nationwide to the China VIb phase in July 2020, with full mandatory enforcement taking effect on July 1, 2023. Since then, new vehicle emissions have significantly decreased, with reductions in carbon monoxide and particulate matter, leading to noticeable improvements in air quality and fewer haze days. Our monitoring data shows a significant decline in urban pollution indices, which helps protect both the ecosystem and public health. We advocate for more people to pay attention to these milestones and choose green transportation options.
