When will China National V Emission Standard be implemented?
2 Answers
China National V Emission Standard was fully implemented on January 1, 2018. The National V Standard refers to the national atmospheric pollutant emission standard titled "Limits and Measurement Methods for Emissions from Light-duty Vehicles (China V)" issued by the Ministry of Environmental Protection in conjunction with the General Administration of Quality Supervision, Inspection and Quarantine. Additional information: The following are the specific details of the National V Standard: 1. The emission control requirements have been further enhanced. The nitrogen oxide (NOx) emission limits have been tightened by 25%-28%, and the particulate matter (PM) emission limits have been tightened by 82%. A new pollution control indicator, the particle number (PN), has been added. The National V Standard applies to vehicles with a maximum gross weight of less than 3.5 tons, including gasoline vehicles, diesel vehicles, gas-fueled vehicles, dual-fuel vehicles, and hybrid vehicles. It is applicable to the design, production, and sales of new vehicles but does not involve vehicles already in use. 2. It will significantly reduce emissions from new vehicles. It is estimated that over five years of implementation, the standard will reduce NOx emissions by 90,000 tons and PM emissions by 20,000 tons. As new vehicles gradually enter the market, the environmental benefits will increase year by year with prolonged implementation. Additionally, the simultaneous supply of high-quality fuel with the implementation of the National V Standard will drive emission reductions in a large number of in-use vehicles, reducing NOx emissions by approximately 300,000 tons and PM emissions by about 30,000 tons annually.
I remember the China National V vehicle emission standards were officially implemented nationwide in January 2017, but some major cities like Beijing and Shanghai piloted them earlier, with Beijing starting as early as 2013. As a car enthusiast, I paid special attention to these changes. The standards forced automakers to upgrade their technologies, significantly reducing engine emissions of pollutants, especially PM2.5 and nitrogen oxides. Back then, when I visited auto shows, I was impressed by the advanced filtration systems in new cars, and the air quality on the streets noticeably improved. Later, the China National VI standards followed, but National V was a crucial turning point that advanced China's automotive environmental protection. I recommend checking the emission level when buying a car to avoid issues with older models. This has had a significant impact on the environment and society, with the overall implementation greatly reducing urban smog.
