Car Life Cycle Inventory Assessment

The first LCA study conducted by the Japan Automobile Manufacturers Association was carried out to calculate energy consumption and CO2 emissions for average passenger cars in Japan. Five stages including mining and producing material, parts and automobile production, operation, maintenance, and disposal and recycling; and inter-stage transportation was included in the scope of evaluation. Energy consumption and CO2 emissions was evaluated and the influence of the average running speed during operation and the influence of part changes were examined.
