Abstract:
Industrial ecology looks at the environmental impact at the level of industrial systems. In particular, Life-cycle
Assessment (LCA) examines the environmental impact of products (and processes) over their entire lifetimes. The
production, use, and ultimate disposal or recycling of any product typically involves many industries. How those
industries interact is related to the structure of the industrial system. Economic input-output models have for some
time now been used to understand the pattern of these interactions with regard to the economic implications. More
recently the value of these models in assessing the environmental implications has been recognized. The authors
have been involved in research that focuses on the incorporation of explicit temporal information into input-output
models as they are applied to LCA.
