Outline of Final Research Achievements

In this study, the specific TMR for about 700 substances, materials, and products have been estimated, and they are available at a website (http://www.ritsumei.ac.jp/~yamasue/tmr/database.html). Economy-wide TMR in Japan from 1990 to 2013 was also estimated, and it showed an increase by 25 % over 23 years. Country-by-country breakdown of TMR enabled a diversity evaluation in terms of resource dependency. The effect of recycling was also evaluated using an indicator of TMR-reduction. Comparison between LCCO2 and TMR provided a quantitative strategy for effective decoupling.
