When will the China 6 emission standard be implemented in Hunan?
4 Answers
Hunan will implement the China 6 emission standard from July 1, 2019, in accordance with the national unified deployment. The country divides the "China 6 emission standard" into two phases: "China 6A" and "China 6B". China 6A is a transitional phase from China 5 to China 6, with lower emission requirements for carbon monoxide, non-methane hydrocarbons, nitrogen oxides, and PM particulate matter compared to China 6B. Below are the official implementation dates for the two China 6 standards: 1. The official implementation date for China 6A standard is July 1, 2020. 2. The official implementation date for China 6B standard is July 1, 2023.
When I bought a car in Changsha last year, I specifically asked about this. Hunan implemented the China 6 emission standards in key cities like Changsha starting from July 1, 2019, a full year ahead of the national schedule. Later in July 2020, the entire province adopted the China 6a standard. Now after July 2023, the whole country has upgraded to China 6b, including all new vehicles in Hunan which must comply with this stricter standard. I think it's good for the environment since reduced vehicle emissions will gradually improve air quality. However, it's worth noting that when buying used cars now, you need to carefully check the emission standards – some older China 5 vehicles might face transfer issues. The most direct impact of such policy changes is that we ordinary people need to be more cautious when purchasing vehicles.
My relative who works at the vehicle management office told me that Hunan implemented China 6 emission standards in two phases. In July 2019, Changsha took the lead as a pilot city, and then in July 2020, the China 6a standard was rolled out across the entire province. Now that the whole country is pushing for China 6b, Hunan is naturally following the new regulations as well. To be honest, this has a significant impact on the auto repair industry. New vehicles compliant with the latest standards are equipped with complex exhaust treatment systems, forcing even experienced mechanics like me, who have run repair shops for twenty years, to relearn new technologies. I suggest friends planning to buy new cars do their homework in advance. Almost all new cars in Hunan now comply with China 6b standards, and even engine oil must be low-ash type to avoid affecting the particulate filter.
Hunan's progress in implementing the China VI emission standards has been quite advanced. I remember that as early as July 2019, Changsha took the lead in implementing the China VI standards, becoming one of the first cities in the country to do so. By July 2020, the entire province required new vehicles to comply with the China VIa standard. The latest development is the upgrade to the China VIb phase in July 2023, with emission limits tightened by nearly half. The policy push has had a significant impact on the automotive industry, and now automakers must prioritize emission control technologies when developing new vehicles. However, for consumers, although China VIb vehicles are slightly more expensive, their environmental performance is indeed much better.
