What is the symbol for China VI emission standard?

[McCarlos]

The symbols for China 1 to China 6 emission standards are I, II, III, IV, V, and VI respectively, with China VI being represented as VI. On July 1, 2000, China first introduced the China 1 emission standard, which was based on European emission standards and aligned with international standards, hence the use of Roman numerals for China 1 to China 6 symbols. The functions of the environmental protection label include: 1. Serving as proof of a vehicle's compliance with emission standards; 2. Acting as the basis for determining the periodic environmental inspection cycle of vehicles; 3. Implementing traffic control measures for high-emission vehicles and serving as a pass for vehicles in restricted zones; 4. Providing a basis for relevant authorities to manage vehicle environmental compliance.
