An EPD turns an LCA into a comparable, third-party-verified declaration. Because it is built on Product Category Rules (PCR) and verified by an independent body, an EPD carries credibility that a self-declared environmental claim does not. In construction, EN 15804 is the core standard that makes EPDs across products and EPD programme operators comparable.
For a Digital Product Passport, an existing EPD is one of the most valuable inputs: it is already verified, already structured around life-cycle stages, and already quantifies impacts like global-warming potential. TracePass can read those values from an uploaded EPD into the DPP's environmental fields, keeping the source attribution so the published passport traces every figure back to the verified declaration.
Frequently asked
What is the difference between an EPD and a PEF?
PEF is the EU's calculation method for environmental footprint; an EPD is a verified declaration document that reports life-cycle results, typically following ISO 14025 / EN 15804 and Product Category Rules. An EPD can report PEF- or LCA-based results, but the EPD is the verified output, not the method.
Is EN 15804 mandatory for all EPDs?
EN 15804 is the core European standard specifically for construction-product EPDs and the basis for declarations used in building-level assessments. EPDs for other product groups follow ISO 14025 and the relevant Product Category Rules; EN 15804 is the construction-sector harmonisation.
