China's National Phase V Emission Standard (China V) was fully implemented nationwide starting from July 1, 2017. The emission control level of China V standard is equivalent to the European Phase 5 emission standard currently in effect. Below is relevant information about China V: 1. The National Phase V Motor Vehicle Pollutant Emission Standard, known as "China V standard", has an emission control level equivalent to Europe's Phase 5 emission standard. 2. The European Union has been implementing this standard since 2009, which imposes more stringent restrictions on vehicle emissions including nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter. 3. From China I to China IV, each upgrade in the standard reduces single-vehicle pollution by 30% to 50%.
