An Environmental Product Declaration — an EPD — is a standardised, third-party-verified document that reports the environmental performance of a product across its life cycle. If that sentence already feels abstract, you're not alone. This article is the plain-English version.
What an EPD actually is
An EPD is a Type III declaration as defined by ISO 14025. The "Type III" matters: it means the document follows a standardised Product Category Rule (PCR), reports a defined set of environmental impacts using Life-Cycle Assessment methodology, and has been verified by an accredited third party who is independent of the manufacturer. It is not a marketing claim. It is not a label. It is a comparable, audited dataset about a specific product.
A typical construction EPD covers the following impact categories across the relevant life-cycle stages (cradle-to-gate at minimum, often cradle-to-grave): Global Warming Potential (GWP, the carbon footprint), ozone depletion, acidification, eutrophication, photochemical ozone creation, abiotic resource depletion (minerals and fossil fuels), water use, and several waste and resource-use indicators. The document also describes the product, its declared unit (e.g. "one cubic metre of ready-mix concrete C30/37"), the scope of the assessment, the data quality, and the verifier of record.
What an EPD is not
- It is not a sustainability rating. An EPD doesn't say a product is "good" or "bad" for the environment. It reports numbers. The numbers can be compared against a benchmark or another EPD with the same PCR — but the EPD itself is data, not a verdict.
- It is not an eco-label. Eco-labels (Type I, like the EU Ecolabel) use pass/fail criteria. EPDs report measurements.
- It is not the same as a carbon footprint. A Product Carbon Footprint (PCF, ISO 14067) covers only greenhouse gas emissions. An EPD covers GHGs and a broader set of impact categories.
- It is not permanent. EPDs typically expire after 5 years and must be renewed if the product, process, or supply chain has materially changed.
The four reasons your company needs one
In our experience there are four reasons a manufacturer ends up sourcing an EPD. Most companies are driven by one of them; some are driven by two or three at once.
1. A regulation requires it
National and regional regulations are the dominant driver. France's RE2020 requires FDES (a national EPD format) for construction products used in regulated buildings. Germany's QNG points to Ökobaudat, which is fed by IBU-verified EPDs. The Netherlands' MPG references the Nationale MilieuDatabase. Denmark's BR18 sets embodied-carbon caps. The US Federal Buy Clean Initiative requires product-specific Type III EPDs for federal procurement of asphalt, concrete, glass, and steel. State Buy Clean programmes in California, Colorado, Washington, Minnesota, Oregon, and others add their own requirements. The list grows every year.
2. A customer requires it
Even where regulation doesn't compel an EPD, a major customer often does. Hyperscalers (Microsoft, Amazon, Meta, Google), automotive OEMs, and large construction primes have begun pushing EPD requirements deep into their supply chains. If your largest customer's procurement form now has an "EPD" line on it, you have a deadline whether you know it or not.
3. A public tender requires it
Public procurement criteria — particularly in Europe and the US — increasingly require product-specific EPDs as a gating criterion. No EPD, no bid. The lead time on a public tender announcement to award is often shorter than the standard 6–12 month EPD timeline, which means companies that don't have one in advance lose the opportunity.
4. Positioning
Some manufacturers commission EPDs proactively to differentiate on sustainability — to give specifiers a comparable, audited dataset to put in front of a client, or to enter a green-building rating system like LEED, BREEAM, or DGNB. This is the smallest of the four drivers in volume, but the most strategic.
The honest answer to "do I need an EPD?" is "yes, if any of (1)–(4) applies — and probably yes within 2–3 years even if none of them apply today, because the regulatory direction across Europe, North America, and Asia-Pacific is clear."
What happens next
If you've decided you need an EPD, the next questions are: which Program Operator? which verifier? what will it cost? and how long will it take? Those questions are easier when you have a few comparable quotes in hand instead of one. That's what EPD Market is for.
