When will the country implement the China VI standard?

It is planned to be uniformly implemented nationwide in 2020 and 2023 respectively. The following is a related introduction to the emission standards: 1. Introduction to emission standards: Emission standards refer to the regulations on the content of harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, particulate matter, and carbon smoke emitted from vehicle exhaust. These standards are established to prevent environmental pollution caused by exhaust emissions from compression-ignition and gas-fueled ignition engines, protect the ecological environment, and safeguard human health. 2. Technical measures: To stably meet the vehicle emission standards, vehicles must be equipped with technical measures that ensure pollutant emissions comply with the national standards, and they must use fuel that meets the standards.
As a car enthusiast, I have always been following the progress of emission standards. I remember that the China 6 standard was implemented from July 2020 for newly produced light-duty vehicles, divided into two phases: China 6a and China 6b. China 6a took effect in July 2020, mainly gradually tightening requirements, while China 6b was fully implemented in July 2023, which is much stricter than 6a, requiring significant reductions in pollutants such as nitrogen oxides. At the time, I saw news that this would push automakers to upgrade their technology, making new cars more environmentally friendly and energy-efficient. Meanwhile, the used car market was significantly affected, with some older models potentially becoming non-compliant. I also heard from friends that choosing a China 6b-compliant car when buying a vehicle might save fuel and reduce long-term maintenance costs. Overall, this standard helps reduce air pollution, especially improving air quality in big cities. However, the wave of car replacements also brought some pressure to consumers, but fortunately, the new car market responded quite quickly.
