Dealing with Emergy Algebra in the Life Cycle Assessment Framework

Life Cycle Inventory (LCI) represents one of the four steps of the Life Cycle Assessment (LCA) methodology, which is a standardized procedure (ISO 14040:2006) to estimate the environmental impacts generated by the production, use and delivery of goods and services and final waste disposal. The calculation of emergy using LCI databases is acknowledged to be of great advantage to improve the accu...
