Environmental Product Declaration(EPD)
Where the EPD is the final report, the foundation of any EPD is a life cycle assessment (LCA). So takes on the LCA as the basis of environmental impact declaration.
These form part of the declaration, on the basis of it being stated as a Cradle to Gate, Cradle to Practical Completion, Cradle to Grave or Cradle to Cradle, all dependent on the product its use and potential for full recyclability of the materials.
For an EPD the LCA must take into consideration your full value chain, from material extraction to manufactured product, its usage stage and end of life, with a declaration of the environmental impact from Carbon Emissions, Ozone depletion, Acidification, Effect on Aquatic Freshwater, Petrochemical Ozone creation and Depletion of Abiotic resources.
The report then has to be submitted to an independent verifier, before being registered on one of the geographic locations focussed EPD Libraries, such as The International EPD System , which is published for many global locations, dependent on what geographical market you are targeting. Market.
In physical terms, an EPD consists of two key documents:
- The underlying LCA report, a systematic and comprehensive summary of the LCA project to support the third-party verifier when verifying the EPD. This report is not part of the public communication.
- Public EPD document that provides the LCA results and other EPD content.
As a voluntary declaration of the life-cycle environmental impact, having an EPD for a product does however not imply that the declared product is environmentally superior to alternatives.
Generally aimed at products for the construction industry to enable designers to seek and select lowest environmental impact products for new designs based on the EPD.
