When will the China VI standard be implemented?

The implementation of the China VI emission standard is carried out in two steps: 1. Starting from July 1, 2019, the China VIa standard was implemented, covering all newly produced light-duty vehicles for sale and registration, as well as all heavy-duty gas vehicles produced, imported, sold, and registered nationwide. 2. Starting from July 1, 2023, the China VIb standard will be implemented, in accordance with the national regulations. Information about the China VI emission standard is as follows: 1. The China VI standard, also known as the 'National Sixth Stage Emission Standard for Motor Vehicles,' includes 'Limits and Measurement Methods for Emissions from Light-Duty Vehicles (China VI)' and 'Limits and Measurement Methods for Emissions from Heavy-Duty Diesel Vehicles (China VI).' 2. The China VI standard was issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection, and Quarantine on December 23, 2016, and June 22, 2018, respectively. 'Limits and Measurement Methods for Emissions from Heavy-Duty Diesel Vehicles (China VI)' has been implemented since July 1, 2019.

When I planned to buy a new car last year, I specifically researched the China 6 emission standards, which were actually implemented in phases. The China 6a standard was uniformly enforced nationwide from July 1, 2019, primarily targeting light-duty gasoline vehicles to begin controlling exhaust emissions. Subsequently, the stricter China 6b standard was first implemented in major cities like Beijing and Shanghai in July 2020, gradually expanding until it became mandatory for all new cars nationwide by July 2023. During my car-buying process, I found that choosing China 6b-compliant models is more environmentally friendly, as they reduce particulate matter and nitrogen oxide emissions, which significantly helps improve urban air quality and lowers the risk of respiratory diseases. Older cars, such as those meeting China 5 standards, depreciate faster, so I recommend prioritizing newer standard vehicles if the budget allows—it’s more cost-effective and hassle-free in the long run. Many automotive forums now discuss how to check a vehicle’s emission label, and when actually purchasing a car, it’s essential to verify the production year and details to avoid buying problematic vehicles from the transition period.

As someone who cares about environmental protection, the implementation timeline of the China 6 emission standards is crucial. The China 6a standard was rolled out nationwide in July 2019 to initially reduce emission pollution, while the more stringent China 6b standard took full effect in July 2023, requiring lower particulate levels. This can significantly mitigate the negative environmental impact of vehicle exhaust, such as improving smog conditions and protecting ecosystems. I usually commute by bicycle, but I also support automobile emission reduction policies as they encourage the development of electric and hybrid technologies. There may be short-term challenges during the promotion phase, but the long-term health benefits are substantial. After 2020, major cities took the lead in accelerating the transition, and car owners should be aware of this and proactively choose low-emission vehicles to collectively foster green commuting habits. Although there are regional differences in standard implementation, such as Beijing's earlier adoption, national consistency remains vital.

Having worked in the automotive industry for many years, I've handled numerous inquiries from car owners about the implementation timeline of China 6 emission standards. The China 6a phase officially commenced in July 2019, covering light-duty vehicles nationwide, while China 6b was gradually rolled out after 2020, becoming mandatory across the country by July 2023. When repairing vehicles, we often see higher parts replacement costs for older cars because the new standards require additional systems like DPF (Diesel Particulate Filter), which can cause issues if not properly maintained. For those who purchased new vehicles after 2019, I recommend regular maintenance of emission control components. Although the implementation was phased over time, the environmental benefits are significant, effectively reducing tailpipe pollution and improving road air quality. As a mechanic, I always remind car owners to check their vehicle certificates to avoid accidentally purchasing pre-standard models. The China 6 standards have also caused considerable fluctuations in the used car market, so extra caution is advised when selecting vehicles.
