Environmental product declaration
An environmental product declaration (EPD) is a document which may be used in different countries to quantifiably demonstrate the environmental performance of a product. They are a Type III environmental label.
The European Standard for the generation of environmental product declarations for construction products, EN 15804, was published by the CEN Technical Committee for the sustainability of construction works (CEN TC350) in 2012.
EPD are generated based on data obtained through Life Cycle Assessment (LCA). An LCA is performed using a peer-reviewed Product Category Rules (PCR) document in line with EN 15804, ISO 14025, and other related international standards.
EPD can be used externally for marketing purposes and internally for the improvement of product manufacture, or process efficiency. They can also feed into whole building assessment schemes, other comparative tools, and building information modelling (BIM) CAD software.
