You are kindly invited to participate to the next seminar organised by DAMAS Work Package III “Process design”:

“Are we responsible for all the environmental impacts that are caused by our actions? – An introduction to different Life Cycle Assessment approaches”

The lecture will be given by: Dr. Dieuwertje Schrijvers, Postdoctoral Researcher at The Life Cycle Group Cyvi – Institut des Sciences Moléculaires, Université de Bordeaux, France.

Environmental problems have gained an important role in the decision-making processes of consumers, companies and policy makers. Life Cycle Assessment (LCA) is one of the most developed and most often applied methods that enables the environmental evaluation of a product. LCA is a multi-criteria tool, calculating the environmental impacts of a full product life cycle: starting from the primary extraction of raw materials, including manufacturing, distribution, the use phase, and final waste treatment at the end of life. Also a broad range of environmental problems can be assessed: ranging from the potential contribution to climate change, land use, loss of biodiversity, and resource depletion to acidification and eutrophication potentials. Although LCA is standardized by ISO 14040 and 14044, there are many different approaches that can be applied in an LCA. The question “What is the environmental impact of a product?” is not sufficiently detailed to be able to do an LCA. There is a significant difference in the impacts for which a product is responsible and the impacts that are caused by the purchase or the use of a product. This difference is especially relevant when co-products, by-products, or recycled products are used or produced in the product’s life cycle. The impacts for which a product is responsible are assessed with an attributional LCA. This approach is most often applied, for example by companies that aim to assess the sustainability of their supply chain. The impacts that are caused by an additional demand for a product are assessed by a consequential LCA. The processes that are affected by this demand – the marginal processes – are generally determined by simplified market mechanisms, due to a lack of economic data. This presentation introduces the main differences between an attributional LCA and a consequential LCA, the different data needs, as well as the different application areas.
