How to distinguish the national emission standard of a vehicle?

Methods to distinguish the national emission standard of a vehicle are: 1. Check the vehicle's environmental protection label; 2. Log in to the website of the Motor Vehicle Exhaust Pollution Supervision and Management Center to inquire; 3. Check the vehicle's factory certificate; 4. Make a rough judgment based on the year the vehicle was registered; 5. Take the motor vehicle registration certificate to the vehicle management office for inquiry. The national emission standard refers to the national standards for motor vehicle pollutant emissions, which regulate the content of harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, particulates, and carbon smoke emitted from vehicle exhaust. The purpose is to reduce and prevent environmental pollution caused by vehicle exhaust, protect the ecological environment, and ensure human health.
To determine the vehicle's emission standard (National I to VI), I believe the most straightforward method is to check the environmental protection label information on the vehicle registration certificate or license. These official documents usually clearly indicate the specific standard from National I to VI. Remember to request these documents when purchasing a car. I personally experienced this when buying a car—the environmental standard number was conveniently and clearly listed on the first page of the registration certificate. The production year can also help estimate the approximate standard. For example, cars produced around 2008 are mostly National III standard, but it's best to confirm with the documents, as different models from the same year may vary. I recommend consulting a 4S store or the vehicle management office to ensure an accurate judgment.
