When was the China III emission standard for vehicles implemented?
2 Answers
China III emission standard for vehicles was implemented on July 1, 2008. Here is relevant knowledge about China III standard: 1. Introduction to China III standard: The abbreviation for the National Phase III Emission Standard, equivalent to Euro III emission standard. This means the content of tailpipe pollutants is equivalent to Euro III levels, with the only difference being that new vehicles must be equipped with an OBD (On-Board Diagnostics) system. 2. Significance of China III standard: Implementing "China III standard" can significantly reduce single-vehicle pollutant emissions, with total emissions being about 40% lower than vehicles meeting "China II standard"; Additionally, by installing the OBD system, individual vehicles emit less pollutants, resulting in smaller environmental impact on atmospheric conditions.
The China III emission standard was officially implemented nationwide on July 1, 2007. I happened to be working at a 4S dealership at that time, so I remember this date particularly clearly. The government required all newly produced light-duty gasoline and gas-fueled vehicles to comply with the China III standard, while heavy-duty vehicles were given a one-year grace period until July 2008. Many car owners rushed to purchase China II-compliant vehicles before the policy took effect, making June of that year exceptionally busy. In fact, Beijing had already piloted the China III standard as early as 2005, but nationwide unified implementation occurred in 2007. This standard raised technical requirements for engines, mandating the installation of OBD systems for exhaust monitoring and catalytic converter upgrades. Looking back now, the China III standard did reduce PM2.5 emissions by approximately 40% compared to China II.
