The "China 6" standard is an upgrade to the "China 5" standard, requiring carbon monoxide emissions and total hydrocarbons to be reduced by more than 50% on the original basis. According to the plan, the "China 6" standard will be divided into two phases: 6A and 6B. The first phase started on July 1, 2020, and the second phase will start on July 1, 2023. The following are the implementation years of other emission standards: 1. China 1 standard, implemented nationwide on July 1, 2001, mainly targeting restrictions on carbon monoxide, hydrocarbons, and particulate emissions. 2. China 2 standard, implemented nationwide on July 1, 2004, requiring a 30% reduction in carbon monoxide and a 55% reduction in hydrocarbons and carbon oxides. 3. China 3 standard, implemented nationwide on July 1, 2007, requiring a 40% reduction in total pollutant emissions compared to China 2. 4. China 4 standard, implemented nationwide on July 1, 2010, requiring a 50% to 60% reduction compared to China 3. 5. China 5 standard, implemented nationwide on January 1, 2018, requiring a 25% reduction in nitrogen oxide emissions compared to China 4.
