| Outline of Final Research Achievements |
A connection table between IO tables and household expenditure statistics was developed. Lifecycle GHG intensity of each item of household expenditure was calculated. Based on these intensities, carbon footprints (CF) of general products of three items, which are rice, ham, and clothing detergent, were calculated according to CFP-PCR. From the social survey, general products' CF are more preferable than GHG emissions from daily lives as reference of product CF. On the other hand, too much information is not preferred,
Implementation of social life cycle assessment (SLCA) and social survey for labor problems of T-shirts were also conducted because of increasing concerns about social problems. From the survey, willingness to pay for avoiding labor problems at a manufacture process was evaluated to be the maximum among various labor problems regarding T-shirts.
