When will China National V Emission Standard be implemented?

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.

When I bought my car, it coincided with the nationwide implementation of the China 5 emission standard in 2017. I had to choose a new vehicle that met the standard to ensure smooth registration. As an ordinary car owner, the most noticeable change was the upheaval in the used car market—prices of China 4 vehicles plummeted, while new cars became slightly more expensive but more environmentally friendly. The air did feel fresher, and I noticed less smoke smell during my morning drives. After the implementation, city regulations became stricter, so I recommend regular maintenance and emission system checks to avoid fines. This standard doesn't just affect car purchases—it also involves maintenance costs and policy changes, making it quite practical. Later, when China 6 was introduced, China 5 seemed basic, but it was a crucial step forward. My daily experience tells me that choosing emission-friendly vehicles is a smart move.

The China 5 emission standard was fully implemented nationwide in 2017, aiming to reduce vehicle pollution. From an environmental perspective, I appreciate that it makes new car emissions cleaner and lowers health risks. Its implementation has driven automakers to innovate with filtration technologies, leading to noticeable improvements in air quality. I've observed urban smog gradually dissipating, for which this standard deserves significant credit. I suggest the government strengthen enforcement to ensure compliance. Environmentally speaking, it's a major step forward.

In 2017, the National V emission standards were fully implemented. After studying the technical details, I found they require new vehicles to improve catalytic converters and diagnostic systems, which are significantly stricter than the previous National IV standards. Manufacturers had to update production lines to add filtration devices, which increased parts and maintenance costs. When actually purchasing a car, you still need to pay attention to whether it complies with local policies. The rapid updates in standards pose considerable challenges for consumers.
