Assessing EPD Compliance with EN 15804

For a product’s EPD to comply with EN 15804, it must be able to measure its performance against the environmental indicators for the five stages in the life cycle of a building.

The ‘product stage’ is mandatory as the impact of  production does not change based on how it is used.  The other main stages have life cycle modules, which are voluntary, depending on their installation, use and disposal.  Each of the five stages is  sub-divided into further life cycle modules.
