China Green Car Ranking
Conventional fuel vehicles emit large amounts of CO2 and tailpipe pollutants during use, significantly impacting the environment and human health. Countries such as the United States, Australia, the United Kingdom, and Japan have developed vehicle environmental rating systems to assess the environmental impact of automobiles.
In November 2010, the Ministry of Environmental Protection (now the Ministry of Ecology and Environment) released the China Vehicle Emission Control Annual Report for the first time. Seizing this opportunity, iCET co-developed the China Environment-Friendly Vehicle Rating System with the Vehicle Emission Control Center of the Ministry of Environmental Protection. The system comprehensively assesses the environmental impact of vehicles throughout production and use, as well as fuel production and distribution. Using vehicle emission standards, fuel type, fuel economy, and vehicle curb weight as basic evaluation parameters, and the vehicle's green score as the primary evaluation indicator, the system conducts green ratings for vehicle models available on the market.

With the advancement of automotive technology and progress in environmental governance, the methodology of the China Environment-Friendly Vehicle Rating System has continuously evolved. The widespread air pollution episode in 2013 also prompted the rating system to pay greater attention to the environmental impact of vehicle exhaust emissions. Consequently, the China Environment-Friendly Vehicle Rating System was upgraded to the "China Green Car Guide," and the evaluation indicators incorporated a "Blue Score" based on exhaust emission assessment.

Through various channels such as publishing annual reports, holding annual award ceremonies, and creating a website platform, the China Green Car Guide recommends lists of green vehicle models to the public and actively promotes environmentally friendly vehicle models through green mobility awareness campaigns. In September 2015, iCET held the "China Green Car Guide" annual award ceremony in Changzhou, Jiangsu Province, elevating the social influence of the "China Green Car Guide" to new heights. Representatives from the US Embassy in China, the US Environmental Protection Agency, American and Israeli business delegations, Peking University, Tsinghua University, and renowned automakers such as Tesla, Ford, Toyota, Nissan, and BYD all participated.
The China Green Car Guide played a significant role in promoting the green transformation of conventional vehicles, encouraging consumers to understand, pay attention to, and purchase green vehicles, and also prompting automakers to pay greater attention to vehicle environmental impact parameters during the manufacturing process.
