Abstract
In this research, for the construction of the sustainable society, we propose the product that can improve the performance making the best use of original longevity and it applies to the car. Then we examined the use of the fuel containing Bio-ethanol aiming at measures for controlling global warming. We calculated the Consumption energy and the amount of the CO_2 exhaust at the production, transportation, refinement, and use stage of the fuel, and evaluated the environmental load by Eco-Efficiency Potential Assessment (E2-PA) at each stage. As a result, the amount of energy consumption from the production stage to use stage increased by 0.1% in the ethanol mixture rate 3 %(E3), 0.3% in 10 %(E10), that of the CO_2 exhaust was reduced 1.1% in E3, 3.7% in E10 compared with gasoline. And the material impact was reduced 3.3% in the ethanol mixture rate 3 %(E3), 11.4% in 10 %( E10) compared with gasoline.
