When did China 6 start to be implemented?

China 6 was fully implemented nationwide on July 1, 2020. Here is the relevant information: 1. Some provinces and cities have already implemented the China 6 emission standard last year. For example, nine provinces and cities including Beijing, Tianjin, Hebei, Shandong, Henan, Shenzhen, and Guangzhou announced that they would implement the China 6 standard in advance on January 1, 2019. 2. Compared with the current nationwide unified "China 5" standard, the China 6 emission standard is more stringent, and the pollutants emitted by vehicles are significantly reduced. Taking light-duty vehicles as an example, carbon monoxide, total hydrocarbons, and non-methane hydrocarbons are reduced by 50%, and nitrogen oxides are reduced by 42%, which is more environmentally friendly.
I've been researching car purchases recently and found that the China VI emission standards were implemented in phases. The nationwide implementation of China VIa officially started on July 1, 2020, and was upgraded to the more stringent China VIb by July 1, 2023. Actually, as early as 2019, major cities like Beijing and Shanghai had already piloted these standards ahead of schedule. According to my research, this was mainly to reduce air pollution, targeting harmful emissions like PM2.5. Newly purchased vehicles must comply with these standards, otherwise they might be restricted from entering certain areas. I was reminded to always check the emission level stated on the compliance certificate before buying a car, ensuring it's not outdated and can be used for several more years.
