The Japanese government announced its mid-term target of reducing greenhouse gas emissions by 26% from 2013 to 2030 at COP21. In Japan, CO2 emissions from the transport sector account for 18.5% of total CO2 emissions, and it is necessary to implement measures in the automobile sector as soon as possible. On the other hand, co-benefit effects such as changes in emissions and noise levels are obtained when global warming countermeasures are implemented. However, previous studies didn't have mentioned co-benefit effects that based on theoretical method. In this study, the authors developed a method for estimating CO2 emissions of automotive sector to consider integrated approaches, and added the calculation of exhaust emission gas and noise levels. Finally, using the developed method, and assuming four scenarios studied by the authors, the effects of technological progress in automobiles and the effects of measures that may be introduced in the future are considered.
