When did China VI emission standard start to be implemented?

China VI emission standard has been fully implemented nationwide since July 1, 2020. More information about China VI is as follows: 1. Automobile emission standards refer to the limits set for harmful gas content in vehicle exhaust, including carbon monoxide, NOx, particulate matter, soot, etc. As vehicle emissions increasingly pollute the environment, China began formulating relevant policy standards to restrict vehicle emissions. Since the implementation of China I standard in 2000, five sets of policy standards have been successively updated, with China V standard currently in effect. 2. Compared with the nationwide unified China V standard, China VI emission standard is more stringent, significantly reducing vehicle pollutants. Taking light-duty vehicles as an example, carbon monoxide, total hydrocarbons and non-methane hydrocarbons are reduced by 50%, and nitrogen oxides by 42%, making it more environmentally friendly. 3. Standards like China V and China VI are national requirements for vehicle emissions, not for vehicle quality. Therefore, China V vehicles can still be driven after the implementation of China VI standard.
The implementation of the China 6 emission standards was divided into two phases. The first phase, China 6a, was rolled out nationwide on July 1, 2020, primarily targeting the production and sale of new light-duty vehicles, requiring a certain reduction in emissions. The second phase, China 6b, is more stringent and became mandatory from July 1, 2023, covering all new light-duty gasoline and diesel vehicles, with significantly tightened pollutant limits—for example, nitrogen oxides were reduced by nearly half. As an ordinary car owner, I've noticed this has impacted the used car market, with older China 5 vehicles depreciating quickly, but new cars are more environmentally friendly, and air quality has improved slightly. In the long run, vehicle maintenance costs may rise, but the environmental benefits are worth it.
The implementation timeline for China 6 emission standards is quite clear. China 6a started in July 2020, while China 6b will be fully implemented by July 2023. As someone who cares about environmental protection, I consider this a milestone in safeguarding urban air quality, reducing PM2.5 and exhaust pollution to make daily life healthier. Automakers are now designing more efficient engines, with new China 6-compliant vehicles featuring lower fuel consumption and reduced emissions. In fact, early-adopter regions like Beijing piloted the standards even earlier. The entire transportation system's green transformation will bring long-term benefits such as reduced respiratory diseases.
