The importance of EPDs

The publishing of a third party verified EPD by a manufacturer indicates a transparent, robust and credible step in the pursuit and achievement of real sustainability in practice. While an EPD in itself is not proof that a product is sustainable, it is a public declaration of the environmental impacts associated with specified life cycle stages of that product.Β  A manufacturer or group of manufacturers, who carry out life cycle assessment (LCA) studies on their product(s) and publish the results in verified EPDs, help to create a knowledge base and an awareness of the environmental impacts quantified using standardised metrics. This allows benchmarking and the identification of improvement opportunities for the product’s environmental credentials. By implication, there are also opportunities for economic and social benefits to the manufacturer, such as the reduction in resource wastage through improvements in product design and manufacturing efficiency.

The reward for EPDs in BREEAM schemes promotes the above, while encouraging designers, procurers and other stakeholders to make decisions on the basis of robust and credible environmental data. This is one of the markers of BRE’s strategic approach to the selection and procurement of construction materials and products.

We recognise that there may be steep costs at the moment to small manufacturers wishing to publish verified EPDs for their products. This is a result of the maturity of the market and it is anticipated that as the awareness of the benefits of EPD increases,Β the increased uptake of EPDsΒ will drive costs down.
