When did China 5 start to be implemented?
2 Answers
China 5, also known as the fifth-stage national vehicle emission standard, was implemented nationwide starting from January 1, 2017. The emission control level of the China 5 standard is equivalent to the fifth-stage emission standard implemented in Europe. Below is a detailed introduction to the vehicle emission standards: 1. China 3 Emission Standard: The specific implementation times were: light-duty diesel vehicles on July 1, 2009; heavy-duty gasoline vehicles on July 1, 2010; heavy-duty gas vehicles on July 1, 2008; and heavy-duty diesel vehicles on July 1, 2008. 2. China 4 Emission Standard: The nationwide implementation times were: light-duty diesel vehicles on July 1, 2013; heavy-duty gasoline vehicles on July 1, 2013; heavy-duty gas vehicles on January 1, 2011; and heavy-duty diesel vehicles on July 1, 2013. 3. China 5 Emission Standard: The nationwide implementation of the China 5 emission standard began on July 1, 2017. Compared to the China 4 standard, it reduced nitrogen oxide emissions by 25% and introduced stricter PM emission limits. 4. China 6 Emission Standard: The China 6 standard is divided into two phases: 6A and 6B. The first phase started on July 1, 2020, prohibiting the sale, registration, and licensing of vehicles that do not meet the 6A emission standard. The second phase will start on July 1, 2023, prohibiting the sale, registration, and licensing of vehicles that do not meet the 6B emission standard.
China's National 5 emission standard was officially and mandatorily implemented nationwide on January 1, 2017, applicable to new vehicle registration. As an automotive technology enthusiast, I observed that this policy had already been piloted in major eastern cities like Beijing, Shanghai, Guangzhou, and Shenzhen as early as 2016, promoting the early sale of National 5-compliant vehicles. The standard focuses on reducing harmful pollutants such as nitrogen oxides and particulate matter, being approximately 40% stricter than National 4, pushing automakers to update engine technologies and install efficient exhaust treatment systems, which significantly reduces air pollution. Understanding this helps car enthusiasts make better vehicle choices, avoid the risk of obsolete models, and contribute to overall environmental progress. Checking the environmental label is crucial when purchasing a car.
