China 6 standard is divided into two phases, a and b. Starting from July 1, 2020 at the earliest, all light-duty vehicles sold and registered must comply with China 6. Below is a detailed introduction to the automotive emission standards: 1. China 3 emission standard: The specific implementation time was July 1, 2009 for light-duty diesel vehicles; July 1, 2010 for heavy-duty gasoline vehicles; July 1, 2008 for heavy-duty gas vehicles and heavy-duty diesel vehicles. 2. China 4 emission standard: The nationwide implementation time was July 1, 2013 for light-duty diesel vehicles; July 1, 2013 for heavy-duty gasoline vehicles; January 1, 2011 for heavy-duty gas vehicles; July 1, 2013 for heavy-duty diesel vehicles. 3. China 5 emission standard: Starting from July 1, 2017, the China 5 emission standard was fully implemented nationwide, with a 25% reduction in nitrogen oxide emissions compared to the China 4 standard, and the addition of PM emission limits, making it more stringent. 4. China 6 emission standard: The China 6 standard will be divided into two phases, 6A and 6B. The first phase starts from July 1, 2020, prohibiting the sale, registration, and licensing of vehicles below the 6A emission standard; the second phase starts from July 1, 2023, prohibiting the sale, registration, and licensing of vehicles below the 6B emission standard.

As someone who frequently pays attention to car purchases, I remember that the China VI policy was implemented in phases: China VIa was mandatorily enforced nationwide for light-duty vehicles on July 1, 2020, requiring all new vehicles to meet the standard; China VIb was piloted in some regions starting in 2021 and was fully rolled out nationwide on July 1, 2023. I must remind you that if you're buying a car recently, it's best to choose a model that meets the China VIb standard, as it's not only more environmentally friendly but also saves on fuel costs. If you're driving an older car, the policy doesn't affect you, but be mindful of the standards when upgrading to avoid restrictions. After the policy was implemented, the air quality improved significantly, with black smoke on the roads reduced by more than half. I support such green initiatives, as everyone benefits from breathing cleaner air. When buying a new car, I always check the environmental label to ensure it meets current requirements.

I have always been concerned about environmental issues. The China VI emission standards came into effect in 2020: China VIa was implemented nationwide in July of that year, mainly targeting gasoline and diesel vehicles; China VIb was gradually introduced in 2021 and covered all newly sold vehicles by July 2023. This has significantly reduced harmful emissions, such as PM2.5 and nitrogen oxides, making a tremendous contribution to the environment. I encourage everyone to prioritize China VIb vehicles when purchasing a car, as they are more efficient and durable, saving maintenance costs in the long run. The policy is driving China's automotive industry toward a cleaner era, and even higher standards may be introduced in the coming years. Every small choice we make can greatly benefit the planet.

Those who have been in the automotive industry for a long time know that the China VI policy has been implementing the China VI-A standard nationwide since 2020. After 2021, China VI-B began to be promoted, and it was mandatorily implemented nationwide in July 2023. This has directly raised the threshold for new vehicles, requiring car owners to confirm specifications when purchasing to avoid buying lower-standard vehicles. I suggest you check the vehicle manual to ensure compliance. The policy has a significant impact, but it makes the air cleaner.
