What is the Beijing Motor Vehicle Emission Standard?

In accordance with national standards, in 2017, key regions including Beijing-Tianjin-Hebei began supplying Phase V vehicle fuel and planned to implement the Phase V motor vehicle emission standard. Starting from 2018, Phase V vehicle fuel was supplied nationwide, which also created conditions for Beijing to implement stricter motor vehicle emission standards. Here is additional information: Emission Implementation: The Beijing VI emission standard refers to the Beijing Phase VI motor vehicle emission standard, which is known as the 'world's strictest motor vehicle emission standard' and was established by Beijing to further reduce motor vehicle emissions. The standard mainly includes specific limit data on harmful substances in vehicle exhaust emissions.

As someone who frequently cares about environmental quality, I understand that Beijing has implemented the China VI-b emission standard, which is the strictest in the country. The limits for pollutants like nitrogen oxides, hydrocarbons, and particulate matter have been significantly lowered, and all newly registered or transferred vehicles must comply. I believe this has greatly contributed to reducing smog. In the past, the sky was often gray in winter, but now the air quality has improved significantly, making outdoor activities much more pleasant, especially in spring and summer. Car owners must ensure they purchase new China VI-compliant vehicles or second-hand cars that meet the standard; otherwise, they won’t be able to register their vehicles and may face driving restrictions. Additionally, Beijing has introduced preferential policies for new energy vehicles and encourages the construction of charging stations, which in the long run can reduce health risks—like my friend’s child, who has experienced fewer allergies. Overall, with strict enforcement of the standards, everyone benefits, and the cleaner air makes walking around feel more refreshing.

I work in vehicle maintenance, and car owners often ask about emission standards. Beijing currently implements China 6b, which is stricter than China 6a, involving upgrades to the exhaust systems of new vehicles, such as three-way catalysts and particulate filters. In practice, owners must ensure their vehicles pass the annual inspection, or they won't be allowed to drive. When assisting, I often check the OBD system for error codes—if emissions exceed standards, parts need replacement or the fuel system requires repair. Beijing's policies are stringent; reselling older China 4 vehicles is restricted. Gasoline vehicles fare better, but diesel vehicles face even higher standards. Owners should pay attention to regular maintenance, like cleaning the throttle body and using high-quality fuel to reduce carbon buildup. From a safety perspective, low-emission vehicles pose fewer accident risks, and cleaner air is more reassuring. I've noticed that after years of enforcement, urban noise has even decreased.

I just changed my car not long ago and chose one that meets the China VI-b standard. Beijing now requires newly registered vehicles to meet this standard, otherwise they won't be registered. Before buying, I did some research and learned that it limits more pollutants with finer control. The 4S store suggested new energy or hybrid models when purchasing, as they pollute less and save on fuel costs. Driving it produces less exhaust with no unpleasant smell, and the air quality on the streets has indeed improved—rolling down the windows doesn't feel stuffy. Related to this, used car transactions require checking the environmental label to confirm the China VI level, which I've encountered trouble with. The policy encourages green travel, which I find quite practical, helping to freshen up the city. Regular maintenance with the right engine oil can keep it up to standard.
