Environmental Product Declarations

A simple black outline of a clipboard with the bold, uppercase letters EPD centered on the board, symbolizing Environmental Product Declarations, set against a plain white background.

Environmental Product Declarations (EPDs) are increasingly vital tools for transparency in building product specification, detailing a product's environmental impact throughout its lifecycle. Based on a Life Cycle Assessment (LCA) and third-party verified, EPDs are governed by Product Category Rules (PCRs) to ensure accurate comparison between products. Architects should note the distinction between Industry-wide EPDs, which cover generic product types, and Product Specific EPDs, which offer greater contributions toward sustainable building credits.
