National Standard Released
On September 28, 2026, the national standard GB/T 48217-2026, "Greenhouse gases — Quantification methods and requirements for product carbon footprint — Electric vehicles," was officially released. Changan Automobile is the lead drafting organization for the standard.
The standard is jointly administered by TC114 (National Technical Committee of Auto Standardization) and the National Technical Committee for Carbon Emission Management Standardization, with TC114SC27 (Electric Vehicles Subcommittee of the National Technical Committee of Auto Standardization) responsible for its execution. The competent authority is the Ministry of Industry and Information Technology. It is a recommended standard and is listed on the standards platform as forthcoming.
Full Life-Cycle Scope
The standard adopts a full life-cycle perspective, covering the entire carbon footprint of an electric vehicle from cradle to grave. This includes upstream raw material and purchased component acquisition, vehicle production and manufacturing, distribution, vehicle use, and end-of-life disposal.
It breaks past the limitation of focusing only on emissions during the vehicle driving phase and aligns with mainstream international carbon footprint accounting methodologies. The standard fills a gap in China's electric vehicle carbon footprint management standards.
Changan's Supporting Work
Changan Automobile also participates deeply in drafting the series of national standards for carbon footprints of power batteries and drive motors, building an integrated vehicle-battery-motor carbon footprint accounting system for electric vehicle products.
