When did China 5 emission standard come into effect?

[BrielleLynn]

China's fifth-stage motor vehicle pollutant emission standard, known as the 'China 5 standard', was implemented nationwide starting from January 1, 2017. The emission control level of the China 5 standard is equivalent to the fifth-stage emission standard currently in effect in Europe. Here is relevant information about the China 5 standard: 1. The European Union has been implementing it since 2009, imposing stricter limits on motor vehicle emissions such as nitrogen oxides, hydrocarbons, carbon monoxide, and suspended particles. 2. From China 1 to China 4, each upgrade in the standard reduces vehicle pollution by 30% to 50%. 3. Cities like Beijing, Shanghai, Nanjing, and some cities in Guangdong have already started implementing the China 5 standard.
