Implementation Time of China 6 Vehicle Emission Standards?

[DiSpencer]

China 6 vehicle emission standards will be officially implemented starting from July 1, 2023. The China 6 standard is divided into two phases: a and b. The earliest implementation began on July 1, 2019, requiring all sold and registered light-duty vehicles to comply with China 6. The requirements for phases a and b are as follows: 1. Phase a requirement: By July 1, 2023 at the latest, all sold and registered light-duty vehicles must comply with China 6. 2. Phase b limit requirement: This means that China 6a can only be considered a transitional phase, while China 6b represents the true China 6 phase. Note: Some regions have implemented the China 6 emission standards ahead of schedule. For example, Guangzhou implemented the China 6 emission standards for light-duty gasoline and diesel vehicles starting from March 1, 2019; Shenzhen required light-duty diesel vehicles to comply with China 6 standards from July 1, 2018, and light-duty gasoline vehicles to comply with China 6 standards from July 1, 2019.
