EPDs, explained for busy manufacturers

What an EPD is, and what it isn’t

An EPD is a third‑party verified, standardized summary of a product’s life‑cycle impacts. Think nutrition label for carbon, energy, and more, written to ISO 14025 and EN 15804 or ISO 21930. It does not claim a product is “green.” It proves comparable facts so project teams can do their math without guesswork.

Why project teams care about EPDs

When an EPD is on the table, specifiers can count real numbers instead of conservative proxies that make products look worse than they are. LEED v4.1 rewards projects that use at least 20 compliant products from 5 manufacturers under the BPDO EPD pathway, with product‑specific Type III EPDs weighted higher in calculations (USGBC, 2024) (USGBC credit library, 2024). That is one reason EPDs nudge bids forward rather than sideways.

The climate context that raised the stakes

Buildings use about one‑third of global energy and account for roughly 34 percent of energy and process‑related CO2. Materials like cement and steel are a big slice of that footprint (UNEP GlobalABC, 2025) (UNEP Buildings‑GSR, 2025). If your product competes in that mix, credible EPDs are the common language buyers expect.

The rulebooks that keep EPDs comparable

A PCR is the rulebook of Monopoly. Ignore it and the game falls apart. For construction, EN 15804+A2 split climate impact into four indicators so results are clearer across fossil, biogenic, and land‑use sources (LCA.no, 2024). Pick the same PCR competitors use when it fits your product. That choice simplifies comparisons and review.

Data you actually need

Plan for one recent 12‑month reference period. Pull energy by process, inbound and outbound transport, bill‑of‑materials, scrap and waste, packaging, and production volumes. New product line just ramping up. A prospective EPD can work with a shorter window, then be refreshed once a full year exists. Reliable cost averages for doing this vary by scope, and good public data is scarce, so anyone promising universal price tags is guessing.

Program operators, without the maze

Smart EPD in the US and IBU in Europe are common, and there are others. What matters most is alignment with your target markets, reviewer availability for your category, publish timelines, and whether they support the languages and formats your distributors need. Pick the one that clears your route to market with the least friction, not the one with the flashiest brochure.

Validity clocks and upkeep that teams miss

Most EPDs carry a five‑year validity period under program rules, and the International EPD System requires an internal annual follow‑up to keep facts current during that window (EPD International, 2025) (EPD International, 2025). Build a renewal buffer of at least 6 months so a PCR change or reviewer backlog does not box you out of a bid.

Speed without chaos

The slow part is never the math. It is herding data across plants, shifts, and ERP instances. A white‑glove approach that collects data at the source lets engineers stay on the line and product managers ship roadmaps. The LCA then lands quickly, and verification feels like a checkpoint, not an audit.

Bottom‑line takeaway

EPDs unlock credibility at the exact moment buyers must justify choices on paper. They shorten debates, protect margin, and make substitutions less likely. If you start with one flagship product, set clean data pipes, and schedule the annual follow‑up, the second and third EPD are not just faster. They are almost boring. That is when you know the system definately works.
