Life Cycle Assessment
Life cycle assessment (LCA) is a rigorous study of inputs and outputs flows over the entire life of a product or process and their associated environmental impact. The underlying peer-reviewed LCA supporting this EPD was performed by the Research Center for Renewable Materials (Laval University, Quebec City) for Lambton doors in 2014. The present LCA is cradle-to-grave, meaning that it includes raw material acquisition, product manufacturing, packaging, construction (shipping and installation), use and end-of-life. The cradle-to-grave processes are presented by Figure 2 . Transportation is represented by âTâ.
