When did China's National VI vehicle emission standards come into effect?

The National VI emission standards for light-duty vehicles were implemented nationwide starting from July 1, 2020. Below is relevant information about National VI: 1. Definition: The National VI Motor Vehicle Pollutant Emission Standards (Phase 6) were 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 pollution from exhaust emissions of compression-ignition and gas-fueled spark-ignition engine vehicles, protect the ecological environment, and safeguard human health. 2. Proposed delay: The suggestion to postpone the nationwide implementation of National VI emission standards was mainly based on two considerations. First, due to the impact of the pandemic, whether automakers could clear their existing inventory before the implementation of National VI standards. Second, the new National VI standards involve particulate matter emission limits, which require new vehicles to undergo corresponding testing and verification. Currently, as work and production resumption have not fully returned to normal, it was hoped that an appropriate delay would give automakers more time.

As a car enthusiast, I vividly remember the implementation timeline of the China VI emission standards. In July 2019, major cities like Beijing and Shanghai piloted the China VIa phase, requiring all newly registered vehicles to comply with this standard, which impacted many car purchase plans. By July 1, 2020, the China VIb standard was fully implemented nationwide for all new vehicles, prompting dealers to clear out old inventory with significant price fluctuations. After its implementation, I noticed a marked improvement in air quality—fewer smoggy days in cities and easier breathing. In the long run, China VIb vehicles are more environmentally friendly and fuel-efficient. I recommend prioritizing them when upgrading your car, as it benefits environmental protection and avoids registration issues. The key milestones were partial rollout in 2019 and nationwide enforcement in 2020.

As an environmental advocate, I highly appreciate the introduction timeline of the China VI emission standards. It started with the trial implementation of China VI-A in selected cities in July 2019, followed by the nationwide enforcement of China VI-B on July 1, 2020. This phased approach has effectively reduced vehicle exhaust pollution, significantly cutting emissions of nitrogen oxides and particulate matter. I've observed more frequent blue skies post-implementation, with evident public health benefits. I recommend regular car owners to purchase China VI-B compliant vehicles or consider new energy options, given the current policy incentives. This is crucial for promoting sustainable social development. The timeline is clear: pilot in 2019, nationwide rollout in 2020.

From my technical experience, the nationwide implementation of China VI emission standards was on July 1, 2020, requiring new vehicles to meet China VI b requirements, while China VI a was first piloted in major cities in July 2019. The standards became stricter, controlling pollutants like carbon monoxide and prompting vehicle design upgrades. That change impacted the automotive market, accelerating the phase-out of older vehicles. When buying a car, pay attention to the label—non-compliant vehicles may face registration difficulties. I recommend regular vehicle maintenance to ensure emissions compliance and avoid hassles.
