How to Determine a Vehicle's Emission Standard (National Standard Level)?

[Nelson]

There are four main methods to determine a vehicle's emission standard (National Standard Level). Below are detailed explanations of these four methods: 1. Compliance Label: Check the back of the vehicle's environmental compliance label sticker. 2. Production Year: The vehicle's production year can provide a general estimate of its emission standard. 3. On-site Inquiry: Bring the vehicle registration certificate to the local vehicle management office for inquiry. 4. Compliance Certificate: Check the emission standard description on the vehicle compliance certificate. The National Standard Level refers to China's vehicle pollutant emission standards, which regulate the permissible levels of harmful gases emitted from vehicle exhaust, including carbon monoxide, hydrocarbons, nitrogen oxides, particulate matter, and soot.
