How to Determine the Vehicle's Emission Standard Level?

Here are the methods to determine a vehicle's emission standard level: 1. Check the Motor Vehicle Conformity Certificate. Vehicles come with this certificate upon leaving the factory, which clearly states the emission standard; 2. Look for the vehicle's packing list. The emission standard can be found in the vehicle information section; 3. Examine the Certificate of Conformity, which includes exhaust emissions and indicates the corresponding emission standard; 4. Query on the Motor Vehicle Environmental Protection Website. Find the public query platform at the bottom of the homepage, enter the vehicle's VIN code and the last 6 digits of the engine number to retrieve the information; 5. Inspect the vehicle's environmental protection label. The back of the environmental protection label on the front windshield clearly marks the vehicle's emission standard.

I think the most straightforward way to determine a vehicle's emission standard is by checking the vehicle nameplate or environmental label. I always pay attention to the small sticker in the lower left corner of the windshield while driving—that environmental label clearly indicates the emission standard, such as China V or China VI. If the sticker falls off or becomes worn, you can also find the VIN code and standard information on the vehicle nameplate under the hood. Additionally, the Motor Vehicle Registration Certificate (commonly known as the 'Green Book') has clear records, which you can request to see when purchasing a car. I've also noticed that many cities implement traffic restrictions based on emission standards—for example, older China II vehicles may be banned from entering downtown areas, which is no small matter, so it's important to confirm early to avoid fines. Some apps like 'Vehicle Management Office Inquiry' tools are quite handy—just enter the license plate number to access detailed data. During routine maintenance, asking a technician to check is also a safer bet, as different emission standards affect tailpipe testing and annual inspection pass rates.
