What emission standard is currently implemented in Beijing?
2 Answers
Beijing is currently implementing the China 6b standard. Below is a detailed introduction to the national emission standards: 1. Purpose: The strict emission standards introduced by the government aim to regulate automakers, and stringent standards can phase out some older vehicles that fail to meet emission requirements. 2. Development of national emission standards: The China 6 standard implemented in 2019 was the China 6a standard, which served as a transitional standard from China 5 to China 6. The true China 6 standard is the China 6b standard. 3. Comparison between China 6a and 6b: The emission requirements for China 6b are nearly twice as strict as those for China 6a, and it also adopts a more rigorous Real Driving Emissions (RDE) test.
As a veteran driver with over a decade of experience in Beijing, I clearly remember when I recently changed cars, the salesperson explicitly stated that only China 6 standard vehicles could be purchased. Beijing's current exhaust emission standard has already reached China 6b, implemented around 2019. All new cars must meet this standard, otherwise, they won't be eligible for license plates. Under the previous China 5 standard, the air quality was terrible, and we had to wear masks whenever we went out. Since the implementation of China 6, strict controls on exhaust pollutants like carbon monoxide and nitrogen oxides have significantly reduced urban smog. Driving feels more environmentally friendly now, and I always advise friends to opt for new energy vehicles or China 6 fuel cars when changing vehicles, avoiding second-hand China 5 cars that can't enter the city. Overall, Beijing's environmental policies are very stringent, which is beneficial for long-term health, though car prices might be slightly higher.
