How to Check Your Vehicle's Emission Standard (National Standard)

[DelAllie]

Here are the methods to check your vehicle's emission standard: 1. The simplest and most direct way is to look at the vehicle's environmental protection label, which clearly indicates the standard on the back. 2. Visit the website of the Motor Vehicle Exhaust Pollution Supervision and Management Center to inquire. 3. Bring the vehicle registration certificate (original or copy) to the vehicle management office for inquiry. 4. For new vehicles, you can check the vehicle's factory certificate. However, the vehicle certificate is usually kept by the vehicle management office. Therefore, when purchasing a new car, it is recommended to make a copy for future reference to check vehicle-related information. Vehicle emission standards refer to regulations on the content of harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, particulate matter, and carbon smoke emitted from vehicle exhaust. Their purpose is to prevent pollution from compression-ignition and gas-fueled spark-ignition engine vehicles, protect the ecological environment, and safeguard human health.
