What is the current vehicle emission standard in China?

The current vehicle emission standard in China is the China VI standard, which stands for the National Sixth Stage Emission Standard for Motor Vehicles. The formulation of the China VI standard is based on the needs of China's national conditions and integrates both European and American standards. It no longer differentiates between gasoline and diesel vehicles, meaning the China VI standard surpasses Euro 6 to become one of the strictest vehicle emission standards in the world. Below are details about the China VI standard: 1. Emission Limits: The China VI standard is an upgrade from China V, imposing stricter controls on pollutant emissions. Compared to China V, the China VI standard reduces carbon monoxide emissions from gasoline vehicles by 50%, total hydrocarbons and non-methane hydrocarbons by 50%, and tightens nitrogen oxide emissions by 42%. 2. Implementation Timeline: The China VI standard is divided into two phases, 6A and 6B. The first phase, starting from July 1, 2020, prohibits the sale, registration, and licensing of vehicles that do not meet the 6A standard. The second phase, starting from July 1, 2023, extends these prohibitions to vehicles not meeting the 6B standard. However, these dates represent the national timeline, and some regions have already decided to implement the standard ahead of schedule.

Now the automotive emission standard has reached China VI, which I'm quite concerned about. Starting from 2020, China VI-b phase was implemented nationwide as the latest standard, much stricter than the previous China V. Harmful substances like nitrogen oxides from vehicle emissions must be controlled at very low levels. Why promote China VI? Simply to improve air quality, reduce PM2.5, and make breathing more comfortable for everyone. If you're buying a new car, it's basically China VI compliant now, and it must pass the vehicle inspection at the DMV. In the future, we might see China VII, as environmental pressures continue to increase. It's also recommended to use higher-grade gasoline for daily driving to reduce impurities, helping your car meet the standards. Remember, this standard affects resale value - China VI cars command higher prices in the used market.

From a consumer's perspective, the current vehicle emission standard is China 6b, which was fully enforced in 2023. This standard ensures lower emissions from new cars, benefiting the environment. When choosing a car, I specifically checked the nameplate to confirm compliance. Previously, China 5 vehicles were sold at lower prices, but now all newly released models must meet the China 6b standard, otherwise they cannot be registered. The advantage is significantly reduced exhaust pollution, contributing to less urban smog. Although the price is slightly higher, it saves fuel and hassle in the long run. I recommend paying more attention to new energy vehicles, such as electric cars, which produce zero emissions. Regular maintenance is also crucial; periodic exhaust testing helps maintain performance.

The current automotive emission standard is China 6, which technically includes two phases: China 6a and China 6b. I work in car maintenance and know some details. China 6b requires ultra-low emissions of carbon monoxide and particulate matter, and vehicles are equipped with a Gasoline Particulate Filter (GPF) for filtration. New vehicles must meet the standard before leaving the factory. Compared to China 5, the progress is significant. Why push for this? Environmental pressures are driving it. In the future, China 7 will be even stricter. To check your car: look at the green book or the manual.

Now the standard is China VI, which I think is super important. With pollution being so severe, China VI vehicles emit much fewer harmful gases, helping to protect everyone's health. I drive every day and pay attention to environmental protection. When buying a new car, I always check for the China VI label. Its implementation has made the air cleaner. I suggest reducing short-distance driving to save fuel and reduce emissions.
