Life Cycle Assessment Methodology 

Life Cycle Assessment (LCA) is an internationally-recognized tool to evaluate the environmental impact of a product or process over the course of its lifespan, from raw material extraction to disposal. The four steps of a Life Cycle Analysis are 1) Definition of LCA goal and scope, 2) Inventory analysis, 3) Impact assessment, and 4) Interpretation. These evaluations can identify aspects of clinical practice that have particularly high environmental impact and guide system-level decision-making to reduce waste, emissions, and often, cost. As an example, please see this LCA of hysterectomies led by collaborator Cassandra Thiel.
