Abstract
In recent years global environmental problems become aggravated, the shift to the sustainable society is required. The quantitative environmental load assessment is necessary to achieve the sustainable society. Though various LCA (Life Cycle Assessment) method is developed for such a demand, it is pointed out that there are a lot of problems in existing LCA. To solve such problems, Eco-Efficiency Potential Assessment (E2-PA) was developed. This research is investigation of "Utility" of the product. Utility is defined as the market price of the product. Setting the market price of the product for criterion variable, Elements of Utility for explanatory variable, multiple regression analysis is done. The accuracy of multiple regression analysis is given to official approval, the Utility is decided. By the result of E2-PA including Utility, the importance of improving the Utility of the product is shown. And aslso To aim at the spread of E2-PA, E2-PA software is developed.
