Abstract

This section, according to the above-mentioned single-vehicle life cycle carbon emission accounting method and the sales volume of passenger vehicles in 2021 (excluding imported models), calculates the life cycle carbon emissions of passenger vehicles on sale in 2021. However some models, due to the lack of key data, are not included in this calculation, and only the carbon emissions of 5313 versions of 981 passenger vehicle models from 115 automobile enterprises, which account for 98.7% of total passenger vehicle sales in China, are considered. The carbon emissions are analyzed by fuel type, vehicle level and life cycle stage, as described below.

Most of the energy consumptions of plug-in electric passenger cars sold in 2021 are still based on NEDC. However, due to the change of testing cycle, the new version of energy consumption test standard has no expression of state A and state B, and there is no corresponding test cycle conversion factor between the new and old standards. Therefore, this report adopts a compromise method to convert the electricity consumption of state A and fuel consumption of state B into the data of corresponding test cycles respectively to approximate the energy consumption of plug-in electric passenger cars under the new test standard.

The models marked by * are simulated models for the purpose of reference.

The data of vehicle population is sourced from the China’s database of compulsory insurance for vehicle traffic accident liability, which collects the relevant information of passenger cars and commercial vehicles including population, vehicle type, fuel type, vehicle age, registration area, energy consumption level and curb weight. For the convenience of calculation, the vehicle population are screened based on key information such as fuel type, vehicle type and vehicle age.
