What is the equivalent of Euro 5 emission standard in China?

China's National 5 emission standard, also known as the fifth phase of the national motor vehicle emission standard, has been implemented nationwide since January 1, 2017. The emission control level of the National 5 standard is equivalent to the Euro 5 emission standard implemented in Europe, which the European Union has been enforcing since 2009. The National 5 standard imposes stricter limits on motor vehicle emissions such as nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter compared to the National 4 standard. Below is the timeline for the implementation of emission standards: 1. National 1 standard, implemented nationwide on July 1, 2001, mainly imposed restrictions on carbon monoxide, hydrocarbons, and particulate emissions. 2. National 2 standard, implemented nationwide on July 1, 2004, required a 30% reduction in carbon monoxide and a 55% reduction in hydrocarbons and carbon oxides. 3. National 3 standard, implemented nationwide on July 1, 2007, required a 40% reduction in total pollutant emissions compared to National 2. 4. National 4 standard, implemented nationwide on July 1, 2010, required a 50% to 60% reduction compared to National 3. 5. National 5 standard, implemented nationwide on January 1, 2018, required a 25% reduction in nitrogen oxide emissions compared to National 4. 6. National 6 standard, with National 6a implemented nationwide on July 1, 2020, and National 6b implemented nationwide on July 1, 2023.
I recall reading materials mentioning this correspondence - the Euro 5 emission standard is roughly equivalent to China's National 5 level. Europe began implementing Euro 5 as early as 2009, while China rolled out National 5 nationwide in 2017. However, it's important to clarify that this equivalence isn't perfectly precise, as the two systems have differences in specific testing procedures and limit requirements. For instance, the particulate matter emission limit for diesel vehicles is 0.005 grams per kilometer under both Euro 5 and National 5 standards, and the nitrogen oxide upper limit is 0.18 grams per kilometer for both. But there are slight variations in some gasoline vehicle indicators. Therefore, parallel import car dealers often directly classify Euro 5 vehicles as National 5 cars - this simplified approach generally faces no obstacles during vehicle registration. If you've purchased such models, you might notice the environmental label states National 5 while the actual certification is Euro 5.
