When will China VI emission standards be implemented?

China VI standards are divided into two phases, a and b. Starting from July 1, 2019 at the earliest, all light-duty vehicles sold and registered must comply with China VIa requirements; by July 1, 2023 at the latest, all light-duty vehicles sold and registered must meet China VIb limit requirements. This means that China VIa can only be considered a transitional phase, while China VIb represents the true China VI stage. More relevant information is as follows: 1. Currently, some regions have implemented China VI emission standards ahead of schedule. For example, Guangzhou implemented China VI emission standards for light-duty gasoline and diesel vehicles starting from March 1, 2019; Shenzhen required light-duty diesel vehicles to comply with China VI standards from July 1, 2018, and light-duty gasoline vehicles to meet China VI standards from July 1, 2019. 2. After the announcement of China VI standards, their extremely strict limit values earned them the title of "the most stringent standards in history." Compared to the current China V standards, China VI standards reduce carbon monoxide emissions by 50%, total hydrocarbon and non-methane hydrocarbon emission limits by 50%, and nitrogen oxide emissions by 42%. All indicators not only fully meet the current EU standards but even exceed them in some cases.

When I bought a new car last year, I paid special attention to the implementation timeline of China 6 emission standards. This standard is divided into two phases: China 6a and China 6b. China 6a was implemented nationwide in July 2020, but major cities like Beijing and Shanghai actually enforced it a year earlier in 2019. I specifically chose a car that complied with the new standard, which not only emits significantly fewer pollutants but also saves me some fuel costs. Looking back now, the air quality has noticeably improved after the policy implementation, and the exhaust smell during traffic jams isn't as strong anymore. China 6b was rolled out nationwide in July 2023, meaning most new cars on the market now meet the highest environmental standards. I'd recommend friends considering a new car to prioritize China 6-compliant models—they're more environmentally friendly, have higher resale value, and are easier to sell in the used car market. Overall, this policy has been quite effective in controlling pollution, making driving on the road much more reassuring.

Having worked in an auto repair shop for a long time, I've seen the significant impact of China VI emission standards. China VI-a was implemented nationwide starting from July 2020, followed by China VI-b which covered the entire country by July 2023. These new regulations have led to major upgrades in emission systems, making sensors and control units more complex during repairs, with parts becoming more precise. I often remind car owners to choose China VI-compliant vehicles when purchasing, to avoid higher maintenance costs later, as older models may phase out quickly. In practice, vehicle emission tests are now easier to pass, and air pollution has decreased noticeably. However, these standards also mean daily maintenance needs to be more meticulous, such as using cleaner fuel types, otherwise the system is prone to malfunctions. Overall, the advancement of China VI standards has made vehicles more environmentally friendly, though with a slight cost increase, posing a challenge for technicians as well.

I strongly support the implementation of China 6 emission standards, as they directly reduce vehicle pollution. After China 6a was rolled out nationwide in July 2020, China 6b followed in July 2023. These two phases have significantly reduced the content of harmful substances in exhaust emissions. It makes me particularly happy to see bluer skies and fresher air in traffic-dense areas every day. The China 6 standards have pushed automakers to design cleaner engines, and every time we drive, we're contributing to environmental improvement. Although the policy may slightly increase the price of new cars, protecting health is more important in the long run. I recommend everyone choose China 6-compliant vehicles and join the environmental action. Reducing pollution is everyone's responsibility.

Having sold cars for so many years, I'm very clear about the timeline for China VI standards. China VIa was fully implemented from July 2020, followed by China VIb in July 2023, and all new cars sold now meet the highest standards. Since then, our dealership has only promoted China VI-compliant models, which have been well received in the market, with customers paying more attention to environmental features. I always highlight the advantages of China VI vehicles, such as lower emissions and stable performance, and can even offer some promotional discounts. After implementation, non-China VI used cars depreciated quickly, making upgrading to new cars a major trend. In my daily work, I see the tangible benefits of these policies being implemented, with real improvements in air quality. I advise buyers to check the emission labels carefully to avoid choosing older models.
