When did the Beijing China VI emission standards come into effect?

Beijing's China VI emission standards were implemented starting from January 1, 2020. The nitrogen oxide emission standard is 0.16 grams per kilometer, the particulate matter concentration emission standard is 0.022 grams per kilometer, and the non-methane hydrocarbon emission standard is 0.18 grams per kilometer. China VI refers to strictly controlling pollutant emission limits. Under conditions excluding working conditions and test influences, the carbon monoxide emissions of gasoline vehicles are reduced by 50%, the total hydrocarbon and non-methane total hydrocarbon emission limits are reduced by 50%, and the nitrogen oxide emission limits are tightened by 42%.
I remember at the beginning of 2020, Beijing started implementing the China 6 emission standard, with the China 6b version officially enforced on January 1, 2020. This standard was introduced to control vehicle exhaust pollution and improve air quality, especially since Beijing had severe smog issues before then. The new regulation required many new cars to meet the standard before they could be driven on the road. At that time, I had just graduated and was buying a car, so I specifically went to a 4S dealership to confirm the standard. The salesperson said that China 6b-compliant cars would be more environmentally friendly but slightly more expensive. After switching to a compliant car, I clearly noticed the air becoming cleaner while driving. I recommend everyone pay attention to local traffic restriction policies and check the China 6 compliance status when buying used cars to avoid unnecessary trouble. Overall, this policy promoted green transportation, and looking back now, it feels quite meaningful.
