Which cities have implemented China 6 emission standards?

Provinces and cities implementing China 6 standards include: Hebei, Henan, Hainan, Chongqing, Anhui, Shaanxi, Sichuan, Chengdu, Hangzhou, Nanjing, Shandong, Shaanxi, and others. Below are introductions to China 6 standards and their implementation timeline: Introduction to China 6: China 6 refers to the implementation phase of motor vehicle exhaust emission testing standards. Additionally, there is a fuel standard. Fuel standards and vehicle emission standards are two completely different concepts, yet they are interdependent. The implementation of new fuel standards means that non-compliant fuels will be discontinued. China 6 standard release dates: The China 6 standards were issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection and Quarantine on December 23, 2016, and June 22, 2018, respectively. The "Limits and Measurement Methods for Emissions from Heavy-Duty Diesel Vehicles (China VI)" came into effect on July 1, 2019. The implementation of China 6 standards imposes stricter requirements on emissions such as carbon monoxide, nitrogen oxides, and hydrocarbons.
Recently, while helping a friend look for a used car, I noticed the implementation of China 6 standards. China 6 is divided into two phases, A and B, with the earliest adoption of China 6B starting in 2019 in Beijing, Shanghai, Guangzhou, Shenzhen, and Tianjin. The following year, the Jiangsu-Zhejiang-Shanghai region, known for its free shipping policies, also fully adopted it, covering the Pearl River Delta city clusters like Dongguan and Foshan. A special case is Henan province, which uniformly implemented the standards in 2021, but China 6A vehicles were given an additional six-month transition period. A reminder to everyone: when buying a car from another region, first check the local environmental protection website. I've seen cases where someone bought a China 5 car that couldn’t be registered in another region, resulting in a wasted trip.
Friends who just bought a new car last year can relate. All 31 provinces and municipalities in China have now implemented the China VI emission standards, but the rollout varies by region. For example, Shandong's 17 cities were divided into three batches for implementation, with Qingdao adopting the standards ahead of schedule in 2019. According to my research, major southwestern cities like Chengdu and Chongqing started in 2020, while mountainous areas may have delayed implementation by half a year. The timelines for heavy-duty diesel vehicles and light-duty vehicles also differ, so commercial vehicle buyers need to carefully check local official announcements for specific deadlines.
