When was the China III standard implemented?
2 Answers
China's Phase III motor vehicle pollutant emission standards were implemented on July 1, 2007. Below is more information about the emission standards: 1. Concept: Automobile emission standards refer to regulations on the content of harmful gases emitted from vehicle exhaust, including CO (carbon monoxide), HC+NOx (hydrocarbons and nitrogen oxides), and PM (particulates, soot). 2. China III emission standards: China's Phase III emission standards are equivalent to the Euro III emission standards, requiring HC emissions to be below 0.2g/km; CO emissions below 2.3g/km; and NOx emissions below 0.15g/km.
When discussing automotive history, I always mention that the China III emission standards were implemented on July 1, 2007, during a period of major transformation in the automotive industry. After the new standards took effect, exhaust emission requirements became stricter, significantly reducing pollutants. The previous China II era had relatively poor emission control, but starting with China III, new vehicles were equipped with more efficient three-way catalytic converters. This technological upgrade greatly improved air quality. Over the years, I’ve followed the evolution of these standards, from China III and IV to China VI, with each version pushing automakers to innovate. However, China III vehicles are now nearly 20 years old, and their value has depreciated sharply in the used car market, especially in areas with environmental traffic restrictions. If you own an older car, it’s advisable to check early whether it complies with the latest regulations.
