How to Check the Emission Standard of a Vehicle?
2 Answers
Methods to check the emission standard of a vehicle are: 1. Look at the vehicle's environmental protection label, which has clear markings on the back; 2. Log in to the website of the Motor Vehicle Exhaust Pollution Supervision and Management Center to inquire; 3. Take the vehicle registration certificate to the vehicle management office for inquiry; 4. Check the vehicle's factory certificate. The production years are categorized as follows: 1. Most vehicles after 2008 are China IV standard; 2. Vehicles registered in 2007 could be China III or China IV; 3. Vehicles before 2007 are mostly below China IV, meaning China III or China II; 4. Vehicles before 2005 are mostly China II standard.
As someone who frequently tinkers with cars, I know there are various ways to check the emission standard level (commonly referred to as "Guo Ji" in China). First and foremost is the vehicle registration certificate, which provides the most authoritative information and directly displays the emission standard grade. Next is the environmental protection label, usually affixed to the windshield or inside the engine hood, with codes corresponding to national standards—for instance, CX often indicates China IV, while DX suffix typically represents China V. The production date combined with regulation implementation timelines is also reliable: China IV was implemented in 2010, upgraded to China V in 2017, and China VI was widely adopted by 2020. VIN code queries offer more comprehensive data—simply input it on official websites or WeChat mini-programs for real-time results. Whenever friends buy new cars, I remind them to check early to comply with urban environmental policies. Higher emission standard vehicles not only save fuel but are also easier to maintain, collectively contributing to pollution reduction. You can handle this yourself without visiting repair shops.
