In June 2016. Below is the relevant introduction: China V: The National Fifth Stage Motor Vehicle Pollutant Emission Standard, abbreviated as "China V Standard", has an emission control level equivalent to the European Union's currently implemented Euro 5 emission standard. The EU has been implementing it since 2009, imposing more stringent restrictions on motor vehicle emissions such as nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter. Differences: Compared to the China IV standard, the new standard can reduce nitrogen oxide emissions by 25% for light-duty vehicles and 43% for heavy-duty vehicles. Based on Shanghai's annual vehicle registration volume of approximately 350,000 units, it is estimated that the annual increase in new vehicles could reduce nitrogen oxide emissions by about 1,000 tons per year.
