Which month's cars in 2015 are National 5 standard?
1 Answers
Different regions implemented National 5 standard at different times: In the Pearl River Delta region, cars manufactured after March 1, 2015 are National 5 standard; in eastern, western, and northern Guangdong, cars manufactured after July 1, 2015 are National 5 standard. Here is additional information: Introduction to National 5: The National Fifth Stage Motor Vehicle Pollutant Emission Standard, known as "National 5 standard," has emission control levels equivalent to the European Union's currently implemented Euro 5 emission standard. The EU has been enforcing this standard since 2009, which imposes stricter limits on nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter emitted by vehicles. Each upgrade from National 1 to National 4 has reduced single-vehicle pollution by 30% to 50%. Differences: The new standard can reduce nitrogen oxide emissions by 25% for light-duty vehicles and by 43% for heavy-duty vehicles. Based on Shanghai's annual vehicle registration volume of approximately 350,000 units, it is estimated that annual new vehicles can reduce nitrogen oxide emissions by about 1,000 tons. Additionally, China's National 5 standard emission control level is equivalent to the currently implemented Euro 5 standard in Europe.
