When was the China III standard implemented?

[EzraAnn]

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.

As an average driver, I personally experienced the implementation of the China III emission standards. I remember starting from July 2007, all new vehicles had to comply with this standard, which reduced emissions and made exhaust fumes less pungent. Back then, I learned right after buying my car that the core of China III was controlling carbon monoxide and nitrogen oxides, a significant improvement over the China II era. Over the years, policies have been continuously upgraded, and now driving a China VI vehicle feels even cleaner. However, the reality is that many old China III vehicles are still on the road, especially in the used car market where they're cheaper. I'd like to remind everyone to always check the emission certification when buying a used car, otherwise you might encounter issues during annual inspections or face restrictions in major cities. In the long run, stricter emission standards have improved both driving safety and environmental quality.

As an environmental enthusiast, let's talk about the implementation of the China III emission standards on July 1, 2007. At that time, China's automobile emission policies became stricter, aiming to reduce pollution and protect the environment. The China III standards required a significant decrease in emissions from new vehicles, such as strengthened particulate matter control, which helped improve urban air quality. From my observation, the standards evolved rapidly, with China V and China VI being introduced successively. Looking back now, China III was a milestone that drove technological innovation in the automotive industry and raised public awareness of environmental protection. In the future, we must continue our efforts to reduce the harm of vehicle emissions.
