When did China 5 emission standard come into effect?

[DawsonRose]

China 5, the fifth-stage national vehicle emission standard, was implemented nationwide from January 1, 2017. Here are details about China 5: 1. Emission control level of China 5 standard: It is equivalent to the fifth-stage emission standard implemented in Europe. The European Union has been enforcing it since 2009, imposing stricter limits on vehicle emissions such as nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter compared to the China 4 standard. 2. Comparison between China 5 and China 4 standards: In comparison, harmful gas emissions like nitrogen oxides from heavy-duty vehicles have been reduced by 43%, while emissions from light-duty vehicles under the new standard have been reduced by 25%. This not only significantly improves the environment but also benefits everyone's health.
