An Environmental Product Declaration, or EPD, reports the environmental impacts of a product using a defined life cycle method. It gives architects and buyers a more useful starting point than a broad claim that a product is “green.” It does not, by itself, tell you which product is best for every project.
Look at the product and declared unit
Begin with the model, configuration and unit the declaration covers. An EPD for one size should not be assumed to represent every size without a clear explanation. Ecolution Design has seven independently verified EPDs selected to cover its Eco Pod range.
Read the life cycle stages
EPDs divide impacts into stages such as raw materials and manufacturing, transport and installation, use, and end of life. Some also report benefits or loads beyond the product system. Check which stages are included before comparing totals. A low manufacturing figure tells only part of the story when another product includes a wider boundary.
Understand the indicators
GWP-total describes global warming potential, commonly expressed as kg CO₂ equivalent. Other indicators may cover fossil resource use, water use, secondary materials, recycling flows and waste. These figures answer different questions. A product can perform well on one measure and less well on another.
Compare like with like
Check the same product function, declared unit, product category rules, methodology, life cycle stages and assumptions. EN 15804+A2 sets core rules for construction product EPDs, while ISO 14025 provides a framework for Type III environmental declarations. An EPD is transparent evidence, not a simple league table.
Use the result in a design decision
Combine the EPD with durability, repairability, acoustic performance and access needs. Ecolution Design's Eco Passports add product-level material information. Read our sustainability approach and explore the Eco Pod range when preparing a comparison.
