An Environmental Product Declaration (EPD) is an independently verified and registered document that communicates transparent information about the life-cycle environmental impact of products. EPDs are based on a Life Cycle Assessment and follow the standard ISO 14025. EPDs are widely used in the construction sector. In Europe, the European Committee for Standardisation has published EN 15804, which defines the “Core rules for the product category of construction products”.
An EPD can be used to perform whole building LCAs (according to EN 15978) or to compare different functionally equivalent products (according to EN 15804). Additionally EPDs are relevant for Green Public Procurement and different types of sustainability certifications/rating schemes for both companies (e.g. BES6001) and buildings (e.g. LEED, BREEAM, DGNB).
