What are the vehicle emission standards in China?

China's emission standards are divided into: National I, National II, National III, National IV, National V, and National VI. Below is an introduction to China's vehicle emission standards: 1. Background: The Chinese government places great emphasis on addressing urban environmental pollution caused by vehicle exhaust emissions. Environmental protection authorities and automobile manufacturers are accelerating efforts to meet National III and National VI standards. Controlling vehicle exhaust pollution has become an urgent and immediate responsibility for environmental protection departments, automobile manufacturers, and all sectors of society. 2. Phases: Phase one, starting from July 1, 2020, all vehicles sold and registered must comply with the National VI A standard; Phase two, starting from July 1, 2023, all vehicles sold and registered must comply with the National VI B standard.
As an environmental volunteer, I have always been concerned about the impact of vehicle emissions on air quality. In our country, the vehicle emission standards have evolved from the National I standard in 1999 to the current National VI standard. The National VI standard is particularly stringent, not only reducing the limits for pollutants like carbon monoxide and hydrocarbons by almost half but also introducing real-driving emission monitoring. I particularly appreciate the phased implementation approach adopted by the government—first introducing National VIa in 2020, then fully implementing National VIb in 2023, giving both automakers and car owners time to adapt. Nowadays, when registering a new vehicle, the system automatically identifies the emission level. I remember during an open day at an inspection station, staff demonstrated the exhaust testing process on-site, and older vehicles that failed were indeed required to return to the factory for rectification. Every time I see clear blue skies and white clouds, I feel these standards are truly valuable.
