What does China VI mean?
2 Answers
China VI refers to the National Sixth Stage Emission Standards for motor vehicle pollutants. Below is a relevant introduction to the China VI emission standards: 1. Definition: China VI vehicles are those that meet the requirements specified in the 'Limits and Measurement Methods for Emissions from Light-duty Vehicles (China VI)'. 2. Implementation phases: The China VI emission standards are implemented in two phases: Phase one, starting from July 1, 2020, all vehicles sold and registered must comply with the China VI-A standard; Phase two, starting from July 1, 2023, all vehicles sold and registered must comply with the China VI-B standard. Some cities may implement the China VI emission standards for light-duty vehicles as early as January 1, 2019.
China VI is the abbreviation for China's sixth-stage vehicle emission standards. During my research on automotive policies, I found that it was implemented in two phases starting from 2019. China VIa served as a transitional period, while China VIb was fully implemented in 2023, aiming to strictly limit pollutants in exhaust emissions such as carbon monoxide, nitrogen oxides, and particulate matter. Vehicles must be equipped with advanced OBD systems to monitor emissions in real-time. Comparing the old and new standards, China VIb has much stricter limits than China V, reducing pollutant emissions by more than half. This has significantly improved urban air quality—for example, PM2.5 concentrations in cities like Beijing and Shanghai have noticeably dropped, making driving safer and more reassuring. In the future, China VII will be even stricter, but the widespread adoption of China VI is crucial now. Environmental protection and health are closely linked, and promoting these standards can reduce respiratory diseases. I recommend prioritizing China VI-compliant models when buying new cars to avoid traffic restrictions.
