Life cycle assessment (LCA) methodologies were originally developed to create decision support tools for distinguishing between products, product systems, or services on environmental grounds. During the evolution of the methodology, a number of related applications emerged, including its use as basis to communicate the overall environmental performance of the products to stakeholders. Specific standards are available for LCA-based environmental labels and declarations. The International Standards Organization (ISO) has classified the existing environmental labels into three typologies—types I, II, and III—and has specified the preferential principles and procedures for each one of them (ISO 14021, ISO 14024, and ISO 14025) (ISO 1999a, b, 2006a; UNOPS 2009). An Environmental Product Declaration (EPD), also referred to as type III environmental declaration, is a standardized (ISO 14025) and LCA-based tool to communicate the environmental performance of a product (Grahl and Schmincke 2007
