SUMMARY: evaluate differences in the application of the methodology and results derived from the use of convencional process based LCA and Environmentally Extended Input Output. 

OBJECTIVES:

Life cycle quantification of sustainability indicators such as carbon footprint, photochemical ozone formation, eutrophication, etc., may be achieved using different approaches. The most common is process based LCA. However, other econometric procedures like Environmentally Extended Input Output may also be used for that end. This project focuses on evaluating differences in the application of these two methodologies in terms of inventory requirements, uncertainty, results, etc. The project involves analysing systems for which precise material/energy and sectorial/economic inventories were available.
