When was the China VI standard for vehicles implemented?

[AlanaRose]

China VI was fully implemented nationwide on July 1, 2020. Here is some relevant information: 1. Some provinces and cities had already started implementing the China VI emission standard in 2019, such as Beijing, Tianjin, Hebei, Shandong, Henan, Shenzhen, Guangzhou, and nine other provinces and cities, which announced that they would implement the China VI standard ahead of schedule on January 1, 2019. 2. Vehicle emission standards refer to the limits set for the content of harmful gases in vehicle exhaust, such as carbon monoxide, NOx, particulate matter, and soot. As vehicle exhaust emissions increasingly contribute to environmental pollution, the government has begun to formulate relevant policies and standards to limit vehicle emissions. Since the implementation of the China I standard in 2000, five sets of policy standards have been successively updated and introduced. The currently implemented standard is the China V standard.
