In recent years, global environmental problems become aggravated, and 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) is developed. E2-PA is based on the concept of "Eco-Efficiency" and the "Potential Assessment". In this research, we pay attention to "Utility", the numerator element of the E2-PA, of the products. Utility is the quantitative index means the essential factors of products in terms of consumers. We propose a method to quantify the Utility, which is the great merit of E2-PA. The targets in this paper are notebook computers. The case study of Utility assessment and calculation of Total Index (TI), which is the integration index of E2-PA. is shown.
