In which year was China 5 implemented?
1 Answers
China 5, the fifth-stage national motor vehicle emission standard, was implemented nationwide from January 1, 2017. The emission control level of the China 5 standard is equivalent to the fifth-stage emission standard implemented in Europe. The European Union has been enforcing it since 2009, with stricter limits on motor vehicle emissions such as nitrogen oxides, hydrocarbons, carbon monoxide, and suspended particles compared to the China 4 standard. More details are as follows: 1. From China I to China IV, each upgrade in the standard reduces single-vehicle pollution by 30% to 50%. Additionally, starting from April 1, 2016, all imported, sold, and registered light gasoline, light diesel passenger vehicles, and heavy-duty diesel vehicles (only for public transportation, sanitation, and postal purposes) in the Beijing-Tianjin-Hebei region must comply with the China 5 emission standard. 2. The motor vehicle pollutant emission standards are formulated to implement environmental protection laws, reduce and prevent pollution from vehicle exhaust, protect the ecological environment, and ensure human health. 3. Compared to the China 4 standard, the China 5 standard reduces harmful gas emissions such as nitrogen oxides by 43% for heavy-duty vehicles and by 25% for new standard light-duty vehicles, significantly improving the environment and benefiting everyone's health.
