Highlights

Japan's economy-wide eco-efficiency of materials and its decomposition analysis are conducted for the first time.
More than 400 materials, 13 impact categories, and 4 life cycle stages were analyzed.
Material groups with a larger share of value added and environmental impact to national total, except for pig iron and crude steel, show lower eco-efficiency.
Resource consumption, land use, and global warming are the main impact categories and foreign supply chains is the major impact stage.
Circular economy and shift to renewable energy to raise eco-efficiency are proposed by material group, focusing on the trade perspective, economic and environmental contribution.
