EPD Environmental product declaration Definition from ISO 14025 / ISO FDIS 21930: • Type III environmental declaration (EPD) provides: • quantified environmental data using predetermined parameters and.. additional environmental information. • The predetermined parameters are based on the ISO 14040 series of Life Cycle Assessment standards • The additional environmental information may be quantitative or qualitative LCM Zürich August 2007
EPD: an information management tool • Communicate environmental and technical information along the supply chain • Give input to building assessments • Input to product development • Backup for communicating environmental performance to the market LCM Zürich August 2007
EPD: an information management tool • Communicate environmental and technical information along the supply chain • Give input to building assessments: LC information, indoor air, soil & water • Input to product development • Backup for communicating environmental performance to the market LCM Zürich August 2007
