Starting from July 1, 2020, urban vehicles sold and registered in Shanghai (including those transferred from other provinces and cities) must comply with the China VIa phase emission standards. Below is relevant information about China VI: 1. Purpose of China VI: The China VI Motor Vehicle Pollutant Emission Standards are established to implement the "Environmental Protection Law of the People's Republic of China" and the "Air Pollution Prevention and Control Law of the People's Republic of China," aiming to prevent pollution from exhaust emissions of compression-ignition and gas-fueled spark-ignition engine vehicles, protect the ecological environment, and safeguard human health. 2. Specific content of China VI: It includes two parts: "Limits and Measurement Methods for Emissions from Light-duty Vehicles (China VI)" and "Limits and Measurement Methods for Emissions from Heavy-duty Diesel Vehicles (China VI)."

I remember in Shanghai, the China VI emission standards started on July 1, 2019, mainly targeting newly sold light-duty gasoline and diesel vehicles at the China VI-b stage. The whole city was adjusting back then because the new standards required stricter control of pollutant emissions, such as reducing carbon monoxide and nitrogen oxides. As a long-time Shanghai resident, I saw many car owners rushing to buy China V vehicles before the deadline, as they couldn’t get licensed afterward. Looking back now, the change was significant—you must check the vehicle’s environmental label when a car, or you’d waste money on something you can’t drive. At the same time, China VI also pushed more new energy vehicles into the market, and Shanghai’s air quality has indeed improved a bit; it’s not as choking during traffic jams anymore.

I worked in an auto repair shop for several years. On July 1, 2019, Shanghai officially implemented the China VI-B emission standard, requiring all newly registered vehicles to comply with much stricter emission limits. This directly impacted engine and exhaust system designs, with catalytic converter issues being common during repairs. Customers often complain about rising car prices or difficulties in dealing with used China V standard vehicles. I'd advise checking the environmental label before purchasing a car to avoid the wrong one. Meanwhile, the China VI standard has also made hybrid vehicles more popular, but special attention should be paid to component compatibility during maintenance, as sensors are prone to malfunction.

I'm a young car enthusiast. The China VI emission standard was implemented in Shanghai in July 2019, causing chaos in the car market. Classic car lovers were particularly upset as some vintage models might fail to meet the stricter emission requirements. The new standard forces manufacturers to develop more advanced engines, though some cars have become slightly slower in acceleration. On the bright side, it's beneficial for the environment - there's less exhaust smell on the streets, making daily driving more comfortable.

As someone who cares about the environment, the implementation of China 6b emission standards in Shanghai on July 1, 2019, was one of the most gratifying events for me. It significantly reduced PM2.5 and harmful gas emissions. This standard mandates that new vehicles meet stringent requirements, helping to alleviate urban smog problems. Every time I check air quality reports, I'm reminded of that transformative moment, which serves as a reminder to prioritize new energy vehicles when choosing a car. Only by aligning with such policies can we collectively create a greener future.

I'm currently getting my driver's license, and my instructor keeps mentioning China 6 standards during driving lessons. In Shanghai, it was implemented starting July 1, 2019, requiring all new vehicles on the road to meet the new standard. This made me extra cautious when choosing my first car—I directly checked the VIN to ensure it's China 6b compliant, avoiding potential registration hassles later. I also learned that China 6 is being rolled out in phases, and it's now the mainstream standard across the market, driving the popularity of more electric vehicles.
