Implementation Date of China VI Emission Standards in Chongqing?
4 Answers
It is expected that Chongqing will implement the China VI emission standards from July 1st this year, for reference only. Whether it will be postponed or not shall be subject to the actual implementation date. Introduction to emission standards: 1. Automobile emission standards refer to the regulations on the content of harmful gases such as CO (carbon monoxide), HC+NOx (hydrocarbons and nitrogen oxides), and PM (particulate matter, soot) emitted from vehicle exhaust. 2. In order to curb the production of these harmful gases and encourage automobile manufacturers to improve their products to reduce the source of these harmful gases, Europe and the United States have formulated relevant automobile emission standards. Among them, the European standard is the automobile emission standard that China has referenced, and domestically produced new vehicles will indicate the European standard that the engine exhaust emissions have reached.
I still remember the timeline for implementing the China VI emission standards in Chongqing. Starting from July 1, 2020, the entire country, including Chongqing, began enforcing the China VIa phase, which was the first step targeting newly sold and registered vehicles. Then, by July 1, 2023, the standards were fully upgraded to the stricter China VIb phase, and now all new vehicles must comply with this standard. I'm quite concerned about environmental protection and enjoy researching these policies because they are crucial for improving urban air quality by reducing pollutant particles in exhaust emissions, making the sky bluer. Especially in Chongqing's mountainous terrain, exhaust tends to accumulate, so with the new standards in place, car buyers now prioritize China VIb-compliant vehicles to avoid future inspection hassles. In the long run, this also pushes automakers to develop new technologies, such as high-efficiency engines and hybrid models.
The implementation timeline of China 6 standards in Chongqing is clearly defined: China 6a phase commenced on July 1, 2020, while China 6b becomes mandatory for all newly registered vehicles citywide starting July 1, 2023. As an automotive technology enthusiast, I'm impressed by this phased approach rather than a blanket enforcement. China 6a serves primarily as a transition, whereas China 6b introduces genuinely stringent emission limits requiring vehicles to adopt higher-efficiency catalytic converters. This significantly contributes to haze reduction, particularly crucial for Chongqing given its industrial density where vehicle emissions account for a substantial portion. When purchasing vehicles, I recommend prioritizing China 6b-compliant models now to avoid premature obsolescence. The future trend leans toward electrification, making China 6b a critical stepping stone.
I'm a taxi driver, driving around Chongqing all day. The China 6 emission standard started with China 6a in 2020, but the changes became more noticeable after the full upgrade to China 6b on July 1, 2023. New vehicle registrations must meet this standard, otherwise they can't be licensed. My old China 5 vehicle can still be used, but the annual emission inspection has become stricter. The new China 6b vehicles are more fuel-efficient with lower emissions, and road conditions have improved slightly. This policy is quite practical for drivers because with reduced exhaust pollution, passengers are more willing to take taxis.
