How to Check a Vehicle's Emission Standard?

[MayaLee]

Methods to check a vehicle's emission standard include: 1. Check the vehicle's environmental protection label; 2. Refer to the vehicle's factory certificate or vehicle conformity certificate; 3. Query through the official Motor Vehicle Environmental Protection Public Inquiry Platform; 4. Determine based on the vehicle's manufacturing year. Emission standards refer to the permissible levels of harmful gases emitted from vehicle exhaust, including carbon monoxide, hydrocarbons, nitrogen oxides, particulate matter, and soot. Vehicle emission standards are established to prevent environmental pollution caused by exhaust emissions from compression-ignition and gas-fueled spark-ignition engine vehicles, protect the ecological environment, and safeguard human health.
