GLRPPR Sector Resource: Economic Input-Output Life Cycle Assessment
Economic Input-Output Life Cycle Assessment
The Economic Input-Output Life Cycle Assessment (EIO-LCA) method estimates the materials and energy resources required for, and the environmental emissions resulting from, activities in our economy. The EIO-LCA method was theorized and developed by economist Wassily Leontief in the 1970s based on his earlier input-output work from the 1930s for which he received the Nobel Prize in Economics. Researchers at the Green Design Institute of Carnegie Mellon University operationalized Leontief's method in the mid-1990s, once sufficient computing power was widely available to perform the large-scale matrix manipulations required in real-time. This website takes the EIO-LCA method and transforms it into a user-friendly on-line tool to quickly and easily evaluate a commodity or service, as well as its supply chain. The results from the EIO-LCA model and this website are free for non-commercial use and may not be used in other derivative works or websites without permission.
