Environmental Product Declarations (EPD) development is not an easy task and the Product Environmental Footprint (PEF) initiative from the European Commission has triggered a lot of discussions. More than three years after the publication of EN 15804, a great number of EPD are already available on the market while some PEF pilots are adressing construction products. Through this event, Construction products Europe bring together environmental assessment experts to collect their ideas on how to best deal with existing challenges, in particular end of life, indicators and benchmarking.
