Environmental Product Declaration (EPD)
An EPD is a standardised, third-party verified document that reports the environmental impact of a product over its life cycle, based on Life Cycle Assessment (LCA) methodology.
What is Environmental Product Declaration (EPD)?
EPDs are governed by ISO 14025 and provide transparent, comparable environmental data for products. They are particularly prevalent in the construction sector, where EPDs for building materials (concrete, steel, insulation, timber) enable architects and engineers to select lower-carbon options. An EPD reports multiple impact categories including global warming potential (GWP), ozone depletion, acidification, and resource use. Product category rules (PCRs) ensure comparability between EPDs for the same product type.
Practical Examples
A concrete supplier publishes an EPD showing its low-carbon mix has a GWP of 180 kgCO₂e per m³ compared to the industry average of 260 kgCO₂e.
An architect specifies EPD-verified materials for a new development, using the GWP data to calculate the whole-life carbon of the building design.
