An Environmental Product Declaration (EPD) is a registered document that provides information about the environmental impact of a product across its life cycle. Unlike a label or certificate, an EPD is not an endorsement of a product’s environmental impact or its compliance with environmental standards. Rather, it provides qualifiable, transparent, and comparable information regarding its life cycle impact in accordance with the ISO 14025 international standards, or “type III environmental declarations.” The procedure for developing and publishing an EPD in the International EPD System involves performing a Life Cycle Assessment (LCA) based on the relevant product category rules, compiling data into the EPD reporting format, verifying findings through an accredited certification body or official verifier, as well as registration and publication. Once published, an EPD is valid for five years, with a few exceptions. EPDs provide information that can be used to communicate relevant environmental information for the improvement of processes along the supply-chain, as well as for marketing purposes. They can also be applied to green public procurement (GPP), environmental management systems (EMS), design, building assessment schemes such as BREEAM or LEED, business-to-business communication, and business-to-consumer communication.
