Study on whole-life cycle automotive manufacturing industry CO2 emission accounting method and Application in Chongqing

摘要

Low carbon economy has become a worldwide trend, many countries are seeking low carbon means to achieve environmentallyfriendly economy growth. However, various Greenhouse gases species in different industries, as well as various detection technology development levels in different countries lead to different carbon emissions accounting results eventually. So the accurate micro-level accounting on carbon dioxide emission is difficult to achieve while in the mean time, it is the basis for subsequent scenario analysis, which plays a crucial role in carbon pricing and carbon credits market promotion. That' s why the regional carbon dioxide emission accounting is a hot issue in low-carbon economy. Nowadays, automotive manufacturing industry has become a big fuel consumer in China and an important source of air pollution. So an accounting method focused on carbon dioxide emission in Chinese automotive industry is essential and practical significant. This paper proposed a whole-life cycle carbon emissions methodology to account carbon dioxide emission in Chinese automotive manufacturing industry, which is based on GREET and MOBILE model. And then the feasibility is verified through application in the automotive industry in Chongqing, China.
