In which year did China's National V vehicle emission standards come into effect?

China's National V emission standards, officially known as the Fifth Stage National Motor Vehicle Emission Standards, were implemented nationwide starting from January 1, 2017. Below is relevant information about emission standards: National V: The Fifth Stage National Motor Vehicle Pollutant Emission Standards, referred to as "National V standards," feature emission control levels equivalent to Europe's currently implemented Euro 5 standards. The European Union has enforced these since 2009, imposing stricter limits on vehicle emissions such as nitrogen oxides (NOx), hydrocarbons (HC), carbon monoxide (CO), and particulate matter (PM). Each upgrade from National I to National IV reduced single-vehicle pollution by 30% to 50%. Comparison with National IV: The new standards reduce NOx emissions by 25% for light-duty vehicles and 43% for heavy-duty vehicles. Taking Shanghai's annual vehicle registration volume of approximately 350,000 units as an example, the annual NOx emissions from new vehicles are expected to decrease by about 1,000 tons. Additionally, China's National V standards match the emission control levels of Europe's currently implemented Euro 5 standards.
As a long-time driving enthusiast, I remember the China V emission standard was implemented nationwide starting from January 2017, especially for light-duty vehicles like sedans and SUVs. Back then, I had just changed my car and specifically researched the update, finding that the new standard aimed to reduce exhaust pollution by requiring lower emissions of nitrogen oxides and particulate matter. In comparison, the previous China IV vehicles had weaker exhaust control, which could easily affect air quality. Nowadays, China V compliant vehicles are common, with convenient maintenance and readily available parts. When buying a car, it's advisable to prioritize this standard—not only is it environmentally friendly, but it also offers benefits in terms of annual inspections and insurance. I believe such policies that drive technological upgrades are beneficial, making our city air cleaner and driving more reassuring. In the long run, supporting higher emission standards means protecting the health of future generations, which is something worth everyone's attention.
