When will China VI emission standards be implemented?
1 Answers
China VI standards are divided into two phases, a and b. Starting from July 1, 2019 at the earliest, all light-duty vehicles sold and registered must comply with China VIa requirements; by July 1, 2023 at the latest, all light-duty vehicles sold and registered must meet China VIb limit requirements. This means that China VIa can only be considered a transitional phase, while China VIb represents the true China VI stage. More relevant information is as follows: 1. Currently, some regions have implemented China VI emission standards ahead of schedule. For example, Guangzhou implemented China VI emission standards for light-duty gasoline and diesel vehicles starting from March 1, 2019; Shenzhen required light-duty diesel vehicles to comply with China VI standards from July 1, 2018, and light-duty gasoline vehicles to meet China VI standards from July 1, 2019. 2. After the announcement of China VI standards, their extremely strict limit values earned them the title of "the most stringent standards in history." Compared to the current China V standards, China VI standards reduce carbon monoxide emissions by 50%, total hydrocarbon and non-methane hydrocarbon emission limits by 50%, and nitrogen oxide emissions by 42%. All indicators not only fully meet the current EU standards but even exceed them in some cases.
