How to Check the Vehicle Emission Standard (China National Standard Level)?

[DelRose]

There are generally four methods. First: Check the back of the vehicle's environmental protection compliance label, which indicates the emission standard. Second: Refer to the vehicle conformity certificate. Third: Determine based on the manufacturing date. Fourth: Inquire at the local vehicle management office. Related Information: Vehicle Emission Standards: Vehicle emission standards regulate the permissible levels of harmful gases emitted from vehicle exhaust, including CO (carbon monoxide), HC+NOx (hydrocarbons and nitrogen oxides), and PM (particulates, soot). Starting from January 1, 2004, Beijing upgraded its vehicle emission standards from Euro I to Euro II, and by 2008, officially implemented the Euro III standard. China Standards: Compared to advanced countries, China's vehicle emission regulations started later and were initially less stringent. Based on China's actual conditions, a phased implementation approach was adopted from the early 1980s, prioritizing easier measures first. The implementation has mainly been divided into three stages up to now.
