When was the China 5 emission standard implemented?

[VonJosiah]

China 5 emission standard has been implemented since January 1, 2017. Additional information: 1. Introduction to China 5: The fifth stage national standard for motor vehicle pollutant emissions, referred to as "China 5 standard", has an emission control level equivalent to the fifth stage emission standard currently implemented in Europe. The European Union has been enforcing this standard since 2009, which imposes stricter limits on motor vehicle emissions such as nitrogen oxides, hydrocarbons, carbon monoxide, and suspended particles. 2. 10% reduction in pollutant emissions: Compared with the China 4 gasoline standard, the sulfur content in the China 5 standard is significantly reduced. According to calculations by the National Standards Committee, the implementation of this standard will greatly reduce vehicle pollutant emissions. It is estimated that in-use vehicles can reduce nitrogen oxide emissions by approximately 300,000 tons annually, and new vehicles can reduce nitrogen oxide emissions by about 90,000 tons cumulatively over five years.
