[LaGianna]

Beijing implemented the China 6 emission standards on January 1, 2020. Currently, the national China 6 standards are divided into two phases: "China 6a" and "China 6b", with nationwide implementation planned for 2020 and 2023 respectively. Here is additional information: 1. The China 6 standards, officially known as "National Sixth Stage Emission Standards for Motor Vehicles", were established to enforce environmental protection laws, reduce and prevent vehicle exhaust pollution, protect the ecological environment, and safeguard human health. 2. The China 6 standards were issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision on December 23, 2016 and June 22, 2018 respectively. The "Limits and Measurement Methods for Emissions from Heavy-duty Diesel Vehicles (China VI)" came into effect on July 1, 2019. The implementation of China 6 standards imposes stricter requirements on pollutants such as carbon monoxide, nitrogen oxides, and hydrocarbons.
