An EPD (Environmental Product Declaration) is a multipage document describing the environmental effects of building products based on a life cycle assessment with quantitative data. It is created by the manufacturer and reviewed at the IBU by independent verifiers on the basis of ISO 14025 and EN 15804 norms, and is subsequently published.
An EPD serves to provide transparency to the public regarding the environmental influences of building products. It is the basis for the ecological evaluation of buildings in building certification systems such as the DGNB or BNB systems, or LEED, BREEAM, and HQE. In addition, EPDs clarify the optimisation potential over the lifetime of their products to manufacturers, who, as a result, can establish processes that conserve more resources, are more environmentally friendly and more economical.
