When was China 5 implemented?

China's National Phase V Vehicle Emission Standard was implemented starting from January 1, 2017. Additional information: 1. The National Phase V Vehicle Pollutant Emission Standard, abbreviated as "China 5 Standard", has emission control levels equivalent to Europe's currently implemented Phase 5 emission standard. The European Union has been enforcing it since 2009, which imposes stricter limits on vehicle emissions such as nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter. 2. Compared to 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 substantially reduce vehicle pollutant emissions. It is estimated that in-use vehicles can reduce nitrogen oxide emissions by approximately 300,000 tons annually, while new vehicles can cumulatively reduce nitrogen oxide emissions by about 90,000 tons over five years.
I recall that the nationwide implementation date of the China 5 emission standards was January 1, 2018, which marked a major upgrade. As an automotive standards enthusiast, I know that transitioning from China 4 to China 5 meant vehicles had to reduce pollution, such as emitting fewer nitrogen oxides and particulate matter. In fact, before the nationwide rollout, major cities like Beijing adopted China 5 as early as 2016 to improve local air quality. After the nationwide unification, automakers scrambled to adjust production lines, adding exhaust treatment devices like GPFs, making new cars more eco-friendly. The used car market also shifted, with China 5-compliant vehicles holding their value better in cities with driving restrictions. In the long run, this change paved the way for the subsequent China 6 standards, driving the industry's green transformation. Though the details are complex, the implementation timeline was crucial for both car purchases and environmental protection.
