Consequential Lca Discussion Forum This is a collection of examples illustrating how to model consequential product systems in life cycle assessment (lca) as it is recommended in the iso 14040 series. It presents the main features of two alternative approaches used in lca attributional and consequential and describes how consequential lca can be performed consistently and appropriately, with an example provided to guide practitioners.
Picture 1 Consequential Lca To assess the potential environmental impact of human industrial systems, life cycle assessment (lca) is a very common method. there are two prominent types of lca, namely attributional (alca) and consequential (clca). Consequential lca estimates the environmental consequences of decisions. instead of asking “what impacts does this product have”, it asks “what changes if we make or don’t make this product”. this approach models how markets respond to changes. Attributional or consequential life cycle assessment? understand the difference between alca and clca to choose the right method for your goals. Attributional lca (a lca) describes the environmentally relevant physical flows to and from a product system. consequential lca (c lca) aims to identify the environmental consequences of a decision, modeling the changes in the entire affected economic system.
Image Consequential Lca Attributional or consequential life cycle assessment? understand the difference between alca and clca to choose the right method for your goals. Attributional lca (a lca) describes the environmentally relevant physical flows to and from a product system. consequential lca (c lca) aims to identify the environmental consequences of a decision, modeling the changes in the entire affected economic system. This chapter presents the topic of consequential lca, with a focus on guidelines for current best practice and identification of gaps for future research. it has been primarily written by bo weidema from 2. 0 lca consultants with tomas ekvall (ivl) as a co author from the calcas project. Tributional lca (alca) modeling. in order to incorporate possible consequences, consequential lca models include additional economic data like marginal production costs, elasticity of supply. This forward looking perspective distinguishes consequential lca from attributional approaches, which allocate existing environmental burdens according to normative rules without necessarily considering market dynamics or system wide responses to change. It presents the main features of two alternative approaches used in lca—attributional and consequential—and describes how consequential lca can be performed consistently and appropriately,.
