How to Check the National Emission Standard?

[LeAdalynn]

Here are five methods to check the national emission standard: 1. Check your vehicle's environmental protection label, which has clear markings on the back. 2. Visit the Motor Vehicle Environmental Protection Website for inquiries. Enter the website, click on the 'Motor Vehicle Environmental Protection Information Verification System' option, select the vehicle type and the passed emission standard, input your vehicle's model and engine type, and click 'Query' to view the emission standard of the vehicle in question. 3. Bring the motor vehicle registration certificate (original or copy) to the vehicle management office for inquiry. 4. If you purchased a new vehicle, you can check the vehicle's factory certificate. Note that the factory certificate is usually kept at the vehicle management office, so it's advisable to make a copy for backup when buying a new car. 5. You can roughly estimate based on the vehicle's registration year. Most vehicles registered after 2008 are National IV standard, those registered in 2007 could be National III or IV, vehicles registered before 2007 are mostly below National IV (i.e., National III or II), and vehicles registered before 2005 are mostly National II standard.
