Abstract
With the application of life cycle assessment method, according to the life cycle assessment standard, the Tesla Model 3 life cycle GHG emissions are accounted applying the CALCM and GREET in this paper obtaining the following conclusions: firstly, the GHG emissions value per unit distance of Tesla Model 3 is 376gCO2e/km, 17% higher than the average GHG emissions of B class ICEV in China, attributing mainly to the high power consumption during driving.
Highlights
With the application of life cycle assessment method, according to the life cycle assessment standard such as ISO 14040[1], ISO 14044[2] and ISO 14067[3], GAC MOTOR CO., LTD. completed the accounting of life cycle GHG emissions of Tesla Model 3 based on real vehicle disassembly data, China Automotive Life Cycle Assessment Model (CALCM) and GREET
The background data for the raw material acquisition phase and power battery production comes from the GREET, and the background data for the use stage comes from CALCM, which is used to carry out the carbon emission calculation of passenger cars developed by Automotive Data Center, China Automotive Technology and Research Center Co., Ltd
The background data of steel, cast iron, aluminum alloy, magnesium alloy, plastic and other materials are derived from the GREET model; according to the disassembly of Tesla Model 3, the main system of automobiles and the list of materials for batteries, liquids, tires, etc. refer to Table 2
Summary
Energy saving and environmental protection are the two major themes for the world automobile development. In the trend of China's power cleanliness, the GHG emissions reduction of new energy vehicles has gradually become an advantage. The GHG emissions of different models of new energy vehicles vary greatly in the whole life cycle. The GHG emissions of certain models of new energy vehicles are even higher than traditional gasoline vehicles of the same class. The GHG emissions of new energy vehicles in their whole life cycle need to be further calculated. Against this background, with the application of life cycle assessment method, according to the life cycle assessment standard such as ISO 14040[1], ISO 14044[2] and ISO 14067[3], GAC MOTOR CO., LTD. With the application of life cycle assessment method, according to the life cycle assessment standard such as ISO 14040[1], ISO 14044[2] and ISO 14067[3], GAC MOTOR CO., LTD. completed the accounting of life cycle GHG emissions of Tesla Model 3 based on real vehicle disassembly data, China Automotive Life Cycle Assessment Model (CALCM) and GREET
