[IrisMarie]

The China V vehicle emission standard was officially implemented on July 1, 2017. Here is more information about China's vehicle emission standards: 1. The China V standard refers to the National Fifth Stage Motor Vehicle Pollutant Emission Standard. After its implementation, the restrictions on motor vehicle emissions such as nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter became more stringent, with single-vehicle emissions reduced by at least 30-50%. 2. After the implementation of the China V emission standard, nitrogen oxide emissions from new standard light-duty vehicles could be reduced by 25%, and heavy-duty vehicle nitrogen oxide emissions could be reduced by 43%, further decreasing vehicle pollutant emissions.
