Where can I check the emission standards of a car?

Methods to check a car's emission standards: 1. You can refer to the car's manual, where the environmental protection green label and the vehicle certification usually have annotations in the vehicle parameters section. 2. Alternatively, you can find the complete vehicle model number on the nameplate below the passenger-side door, then visit the Motor Vehicle Environmental Protection website, enter the complete vehicle model number in the search box, and check the car's emission standards. Here is some related information: 1. Car emission standards refer to regulations on the content of harmful gases emitted from vehicle exhaust, such as CO (carbon monoxide), HC+NOx (hydrocarbons and nitrogen oxides), and PM (particulate matter, soot). 2. With the rapid increase in the number of cars, traffic congestion has become commonplace, and the excessive vehicle exhaust is highly detrimental to health. 3. Exhaust gases contain 150 to 200 different compounds. Since vehicle emissions are mainly released at heights between 0.3 meters and 2 meters, which is within the human breathing range, they cause severe harm to health. The most harmful components include carbon monoxide, hydrocarbons, nitrogen oxides, and solid suspended particles.
As an ordinary person who frequently drives, I find the easiest way to check a car's emission standard is on the vehicle registration certificate, which is the official document provided when purchasing the car, stating information like China V or China VI. For used cars, the environmental label sticker on the corner of the windshield usually displays the standard, making it easy to see. Sometimes, the label on the inside of the door also has relevant markings, so I just open the door and take a quick look. Emission standards are quite important as they affect how many years the car can be driven and urban traffic restriction policies, such as lower-emission cars being allowed to drive longer. I recommend checking regularly because vehicle aging may lead to changes—don’t wait until you get a ticket to find out. You can also enter the VIN number on the DMV website for a free and accurate check, which is very convenient.
