When will the China 6b standard be implemented?

[Emiliano]

China 6b will be implemented on July 1, 2023. Currently, multiple provinces and cities have announced the early implementation of the China 6 emission standard (among them, Shanghai, Guangzhou, Shenzhen, and Tianjin will directly implement the stricter China 6b standard on July 1, 2019, while Beijing will directly implement the China 6b standard on July 1, 2020). Here is more information about China 6b: 1. China 6b refers to the second phase of the China 6 standard for vehicles. From the perspective of vehicle emission standards, the China 6b standard is much stricter than the China 6a standard. 2. China 6b comprehensively controls carbon monoxide, hydrocarbons, nitrogen oxides, particulate matter, etc. Compared to the China 5 standard, the China 6 standard aims to reduce vehicle pollutants by half. The China 6 standard introduced by China is divided into two phases: China 6a and China 6b, so the implementation times for the China 6a and China 6b emission standards are also different.
