When will China VI emission standards be implemented?
2 Answers
China VI emission standards will be implemented in two phases: "China VI A" and "China VI B", with corresponding implementation dates of July 1, 2020 and July 1, 2023. Here is an introduction to China VI standards: 1. Overview: The China VI motor vehicle pollutant emission standards are established 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 environmental pollution caused by exhaust emissions from compression-ignition and gas-fueled ignition engine vehicles, protect the ecological environment, and safeguard human health. 2. Content: The standards consist of two parts: "Limits and Measurement Methods for Emissions from Light-duty Vehicles (China VI)" and "Limits and Measurement Methods for Emissions from Heavy-duty Diesel Vehicles (China VI)".
I remember the implementation timeline of China 6 emission standards was quite deliberate. China 6a was first rolled out in key cities like Beijing and Shanghai around July 2019, then expanded nationwide by July 2020. I happened to be changing cars at that time, and there were many China 5 vehicles being cleared from inventory at significantly discounted prices. China 6b was originally planned for earlier implementation but got delayed, finally becoming mandatory nationwide in July 2023. This had a major impact on new car buyers - you had to carefully check emission standards when purchasing to avoid policy-related issues. As someone who's been driving for over a decade, I think these standards are gradually improving air quality, but they've also made used car transactions more complicated since older vehicles depreciate faster. Looking back, understanding these timelines in advance could have saved a lot of trouble.
