China 6 emission standard is implemented in two phases. From July 1, 2020, the China 6A standard was implemented. From July 1, 2023, the China 6B standard was implemented. The following is the significance of the implementation of the China 6 emission standard: 1. International competitiveness: From originally following the European and American motor vehicle emission standards to being independent and innovative. For the first time, it has led the world in standard setting, which helps Chinese automobile companies participate in international market competition and improves the international competitiveness of China's automobile industry. 2. Industrial upgrading: Under the background of China's overcapacity in the automobile industry, it can play a role in eliminating backward production capacity and leading industrial upgrading. 3. Environment: It can meet the requirements of key regions to tighten automobile emission standards in order to accelerate the improvement of ambient air quality.
I remember the China VI emission standards quite clearly, as they almost affected my car replacement plan. The nationwide implementation was divided into two phases: China VIa officially took effect in July 2020, while China VIb wasn't fully implemented until July 2023. However, some major cities like Shenzhen and Guangzhou took early action, enforcing the standards as early as 2019. When I was car shopping at the dealership, the salesperson specifically reminded me that new vehicles must be equipped with particulate filters, with exhaust emissions limited to no more than 500mg of carbon monoxide per kilometer. The new standards are so strict that many automakers had to modify their engines overnight. I heard the clearance sales of non-compliant inventory vehicles were quite a spectacle.
