What is the difference between yellow label and green label in vehicle inspection?

[DiEmma]

The difference between yellow label and green label in vehicle inspection lies in their emission levels: yellow-label vehicles have higher exhaust emissions, while green-label vehicles meet the corresponding standard requirements. Yellow-label vehicles refer to passenger vehicles issued with yellow environmental labels by environmental protection departments, and green-label vehicles refer to passenger vehicles issued with green environmental labels by environmental protection departments. Many regions and cities across the country have begun implementing the China VI emission standards. The China VIa standard stipulates: 1. Gasoline vehicles must not emit more than 700 milligrams of carbon monoxide per kilometer driven; 2. Gasoline vehicles must not emit more than 68 milligrams of non-methane hydrocarbons per kilometer driven; 3. Gasoline vehicles must not emit more than 60 milligrams of nitrogen oxides per kilometer driven; 4. Gasoline vehicles must not emit more than 45 milligrams of PM fine particles per kilometer driven.
