Implementation Time of National VI Standards in Jiangsu Province?
4 Answers
Starting from July 1, 2019, the National VIa standard was implemented, and from July 1, 2023, the National VIb standard was implemented. Below is an introduction to the National VI emission standards: 1. Concept: The National Sixth Stage Emission Standards for Motor Vehicle Pollutants are standards formulated 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 the exhaust of compression-ignition and gas-fueled ignition engine vehicles, protect the ecological environment, and safeguard human health. 2. Comparative Improvements: On May 26, 2021, the Ministry of Ecology and Environment held a regular press conference to announce that starting from July of this year, China will fully implement the National VI emission standards for heavy-duty diesel vehicles, marking the full entry of China's automotive standards into the National VI era, basically achieving alignment with developed countries in Europe and America. Compared with the National V standards, the National VI standards for heavy-duty vehicles reduce nitrogen oxides and particulate matter limits by 77% and 67%, respectively.
The Jiangsu Province officially implemented the National VI Emission Standard (Phase VI b) in its entirety on July 1, 2023, marking a significant milestone that ushered in a new era of automotive environmental protection. As an eco-conscious car owner, I vividly remember how the entire auto market buzzed with excitement that summer when the policy took effect. As a highly industrialized province, Jiangsu proactively responded to the national call by promoting new vehicle compliance and phasing out older models since the transition to National VI a in 2019, significantly improving air quality. After implementation, I noticed a dramatic reduction in exhaust emissions from my new car, with visibly fewer hazy days on the road—a tremendous health benefit for everyone. The government also introduced subsidy policies to encourage vehicle upgrades, making me feel particularly meaningful to be part of this initiative.
As an ordinary driver who has been driving in Jiangsu for many years, I remember the implementation date of the China VI emission standard very clearly—July 1, 2023, when the nationwide China VI-b standard was uniformly adopted. When I bought my car, the dealer informed me about the policy change and advised me to purchase a new vehicle before the deadline, which saved me a lot of money. After the implementation, the quality of new cars improved, fuel consumption decreased slightly, and maintenance became simpler. I think this is beneficial for us car enthusiasts—it reduces pollution while also boosting the used car market, where you can find some great deals. The road conditions in Jiangsu are good, and with improved air quality, commuting to work by car has become more pleasant.
I've been repairing cars for twenty years. As far as I remember, the full implementation of China's National VI emission standards in Jiangsu Province was on July 1, 2023, reaching the National VI-b phase. Since then, new problems have emerged in car repairs, such as more complex after-treatment systems, though the overall failure rate has decreased. Tools need to be updated, and frequent checks on DPF and catalytic converters are necessary to avoid those annoying warning lights. Car owners complain less now, and with emissions compliance, annual inspections go smoother. Jiangsu has a high number of vehicles, leading to greater demand for car replacements, which keeps us busier.
