英文摘要: The present study demonstrates how the environmentally weighted material consumption (EMC) indicator can be used to assess the resource efficiency of bioeconomy policies by calculating thirteen categories of environmental impacts associated with the production and the use of 146 biomass resources in Japan. The total environmental impact, expressed in the Japanese life cycle database in Japanese yen (JPY), decreased from 2,444 × 109 JPY in 1990 to 1,870 × 109 JPY in 2010. Supply chain related emissions (upstream) represented more than 98% of the impacts for all years. Land use, resource consumption, global warming, and urban air pollution were the main impact categories accounting respectively for 45%, 32%, 14% and 8% of the impacts. Ten products were found responsible for more than half of the impacts: rice, raw milk, beef cattle, painted printing paper, broiler, rolls of newsprint, hen egg, squares, common plywood and lumbers. Improvement of the production processes, reduction of consumed amounts and dietary change were identified as potential strategies for reducing the environmental impacts of these materials. Still, finding the best policy option may require the development of a life cycle assessment database able to differentiate organic and conventional agriculture and to better represent the production and environmental specificities of importing countries. © 2020 Elsevier Ltd Citation statistics:
