Outline of Final Research Achievements

A global link input-output model of multiregional input-output model, which combined global material flow data on metal resources and Japanese input-output table, measured material footprints (MF) of the resources and greenhouse gases emissions induced by final demand in Japan through the international supply chain. Mining risk on each metal resource was also quantified by using the political risk of mining countries and the global market concentration of the metal output, and attribution of the mining risk to Japanese economy was calculated based on the magnitude of the Japanese MF. In addition, focusing on changes in the household composition and the population the due to the declining birth rate and the aging population, the household consumption by household type from 2005 to 2035 were estimated and employed to analyse the future changes in the consumption-based GHG and MFs of rare metals associated with household consumption in Japan.
