Environmental hotspot analysis attracts attention as a tool to identify the important aspect of products and services. In addition, not only evaluation of only climate change (carbon footprint) but also the importance of evaluation in consideration of other environmental impact category is increasing. Inventory data with a elementary flow sufficiently is an indispensable element for these evaluations, but there is an elementary flow that is deficient even in Japan’s largest database, IDEA, thus the evaluation cannot fully achieve. Therefore, the aim of this study is to prepare inventory data for environmental hotspot analysis, focusing mainly on 17 impact categories (global warming, ozone depletion, water resource consumption, land use, air pollution, photochemical oxidant, acidification, eutrophication, noise, forest resource consumption, fossil fuel consumption, mineral resources consumption, waste, human toxicity, ecotoxicity, indoor air quality contamination, ionizing radiation). We have expanded elementary flows related to the impact category to each unit process of IDEA for multi criteria analysis. In addition, we integrated with elementary flows of IDEA’s 1895-unit processes, the I/O table including wastes for environmental hotspot analysis. This paper outlines the database construction method.
