In which year did the China V emission standard come into effect?

The China V emission standard was implemented nationwide starting from 2017, with the specific implementation date being January 1, 2017. It refers to the fifth stage of the national motor vehicle emission standards. Additionally, as of April 1, 2016, all imported, sold, and registered motor vehicles in the Beijing-Tianjin-Hebei region and some major cities were already required to comply with the China V emission standard. Reasons for implementing China V: The key factors contributing to global temperature rise and severe urban smog are vehicle emissions. Therefore, emission standards have been continuously upgraded from China I to IV, and then to China V. Each upgrade reduces vehicle pollution by 30% to 50%. China V imposes stricter limits on nitrogen oxides, carbon monoxide, and particulate matter in vehicle exhaust. Moreover, Western countries have already implemented the fifth-stage emission standard since 2009. Differences between China V and China IV emission standards: Compared to China IV, the China V standard reduces nitrogen oxide emissions from heavy-duty vehicles by 43%, and nitrogen oxide emissions from light-duty vehicles by 25%. Therefore, the implementation of China V not only significantly improves the environment but also benefits everyone's health.

As a car enthusiast who frequently researches, I remember the China 5 emission standard was officially implemented nationwide in 2017, specifically on January 1st, with some major cities piloting it earlier in 2016. This standard mainly targeted new vehicles, requiring reduced nitrogen oxide and particulate emissions, being much stricter than the previous China 4 standard. For car enthusiasts like us, it drove engine technology upgrades, such as more vehicles adopting direct injection systems. However, car buyers should check the manufacturing year when purchasing used cars, as pre-2017 China 4 vehicles may face registration restrictions or faster depreciation. Now with China 6 standards in place featuring even stricter emissions, 2017 marked the first step in environmental upgrades, contributing significantly to urban air quality improvement. I must say learning this knowledge helps people make wiser car choices.

Speaking of the China 5 emission standard, I think its launch in 2017 was quite pivotal. That year when I bought a car, the salesperson explained this to me—previously it was the China 4 standard, and by 2017 there was a full transition to China 5, meaning new cars had to meet the standard to be registered. The benefit was a reduction in pollutants like PM2.5, making it more environmentally friendly. For us car owners, there wasn’t much impact—just a slightly higher car price, but long-term maintenance costs remained similar. Later, the promotion of China 6 was also an upgrade based on this foundation. I’d suggest friends pay more attention to policy changes so they don’t lose out when buying a car.

Speaking of the China V emission standards, they were officially implemented in 2017. I know these standards were introduced to control vehicle exhaust pollution and are stricter than China IV. After implementation, new vehicles had to pass tests to reduce harmful emissions, which didn't really burden daily driving. Since that year, air quality has gradually improved, which is quite meaningful.
