The standards for Environmental Product Declarations (EPDs) are:
ISO 14025:2006 Environmental labels and declarations -- Type III environmental declarations -- Principles and procedures, and
ISO 21930:2007 Sustainability in building construction -- Environmental declaration of building products
EPDs are defined by ISO 14025 as being “quantified environmental data for a product with pre-set categories or parameters based on the ISO 14040/4 standards (LCA), but not excluding additional environmental information.”
An EPD provides o a single source of scientifically robust and transparent information about a product’s environmental impact, verified by a qualified third party. o a summary of the important environmental impacts of a product through its life cycle; o in accordance with publically available criteria (product category rules); o that is verified by an independent authority.
To meet ISO requirements, an EPD must meet four criteria:
Increasingly, specifiers and purchasers are seeking the credibility and transparency provided by a Type III (EPD) independently verified. In today's marketplace (whether national or global in scope), it is no longer sufficient for manufacturers to make claims that are not certified to a recognised and transparent standard with the results verified by a qualified third party expert. In particular, European Governments are setting mandates for Type III independently verified EPDs for products.
