When was the China III Standard Implemented?

[LaHarrison]

National Phase III Motor Vehicle Pollutant Emission Standards were implemented on July 1, 2007. Below is more information about emission standards: 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 (particulate matter, soot). China III Emission Standards: National Phase III emission standards are equivalent to 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.

As a veteran driver with over 20 years of experience, I remember the China III emission standards officially took effect on July 1, 2008, for newly registered vehicles. At that time, I was planning to change my car, and many dealerships reminded me that new cars had to meet this standard to get licensed plates. The China III standards primarily aimed to reduce vehicle exhaust pollution, such as carbon monoxide and particulate matter, helping improve urban air quality. In the long run, this standard drove technological advancements, like many new cars being equipped with more advanced exhaust purification devices. Later, the standards were upgraded to China IV, China V, and now China VI, gradually tightening requirements. Looking back, the implementation of China III led to the phasing out of many older vehicles, transforming the used car market and tightening traffic restriction policies. After all these years of driving, environmental standards have changed so quickly that car owners must keep up with the times.

Before buying a car, I did a lot of research. The China III emission standard officially took effect for newly produced vehicles on July 1, 2008. As an ordinary car owner, I remember dealers saying this standard required new cars to reduce pollutant emissions, aiming to mitigate the impact of smog in major cities. From a personal perspective, China III drove many improvements, such as adding new filters to diesel vehicles. In fact, after the standard was implemented, air quality did improve significantly, especially in congested cities like Beijing and Shanghai. In the following years, the standards were upgraded again—China IV in 2011, China V in 2017, and now China VI is even stricter. Be careful when buying used cars; you can check whether it's a China III vehicle by looking up the VIN or registration certificate. The evolution of environmental standards reminds us to pay more attention to green travel when driving.

When working in repair shops, I often deal with vehicle emission issues. The China III emission standard was implemented for new vehicle registrations starting from July 1, 2008. During vehicle inspections, you can determine compliance date by checking the nameplate or VIN code. China III introduced OBD systems to monitor emissions, triggering alerts if values exceed limits. Technically, it targeted exhaust purification devices for both gasoline and diesel vehicles. After implementation, maintenance costs increased for older vehicles, so novice buyers should carefully inspect to avoid problematic models. With the upgrade to China IV standards, the technology became more mature, making vehicle ownership much more worry-free.
