What is the current national emission standard for automobiles?
2 Answers
Currently, the national pollutant emission standard for motor vehicles is at China V (National Standard V). Here are details about China V: 1. Standard Release: On September 17, 2013, the Ministry of Environmental Protection issued the 'Limits and Measurement Methods for Emissions from Light-Duty Vehicles (China V)'. Starting from January 1, 2017, all motor vehicles nationwide fully implemented the China V emission standard. 2. Differences: Compared to China IV, the new standard reduces nitrogen oxide emissions from light-duty vehicles by 25% and from heavy-duty vehicles by 43%. 3. Implementation Status: In September 2013, Beijing became the first city in China to implement the China V emission standard for light-duty vehicles.
I usually pay attention to environmental policies. Most of the current vehicle emission standards are China 6 (also known as China VI). The China 6 standard has been implemented since 2019 with the aim of reducing air pollution and cutting emissions of harmful substances such as PM2.5 and nitrogen oxides. It is divided into two phases: China 6a and China 6b, with China 6b being stricter. This year, it has been fully implemented nationwide. When buying a car, you can check the vehicle's environmental compliance certificate or the MIIT fuel consumption label to confirm which standard it meets. China 6 vehicles require better engine technology and fuel quality, helping us improve urban smog issues. Although there are still older China 5 vehicles on the road, newly registered cars must comply with China 6 standards, which is crucial for environmental protection. The government may introduce China 7 standards in a few years, but currently, China 6 remains the mainstream.
