How to Check Which National Emission Standard Your Vehicle Meets?

[PaulLee]

To determine which national emission standard your vehicle meets, you can follow these methods: 1. Look for the environmental compliance label on the front windshield of your car. The label's backside will provide the necessary information; 2. Search through your vehicle's purchase documents for the vehicle conformity page or the page starting with the vehicle certification number. These pages contain details about the emission standard, though not directly stated as "National X". Instead, you'll find a string of characters that represent the standard, which you can search online to decode. Vehicle emission standards are regulations set by the government to limit the amount of harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, and particulate matter (PM) emitted from vehicle exhaust.
