Life Cycle Assessment
Life cycle assessment (LCA ) has its name from the vital insight that products, and thus the services derived from them, can cause environmental impacts at all stages of their life cycles, from material and energy resource extraction, through material and component production, product distribution and use, all the way to the end of the product’s life. One of the earliest examples was a comparison of beverage containers in 1969, conceived and funded by Coca-Cola and conducted by Midwest Research Institute. As the number of life cycle studies increased over the years, their limitations and shortcomings also became more apparent. Standards like ISO 14044 have resolved many, but not all, methodical challenges. Today, we also distinguish between LCAs that generate environmental profiles of existing products systems (attributional) and LCAs that study the consequences of changes in product systems (consequential). We conduct both types of LCAs for products systems of high interest and also work on advancing LCA methods and theory.
