Does GSA allow industry-average EPDs for low-embodied-carbon bids?

No. The EPA Interim Determination and GSA FAQs specify **product-specific, third-party verified** EPDs. Industry-average or fabricator declarations are rejected (GSA FAQ, 2025).

When during the bid do I need to submit the EPD?

Project documents spell it out, but most GSA solicitations require the EPD **at bid submission or before notice to proceed**. Waiting until post-award risks disqualification (GSA FAQ §5, 2025).

How often must a verified EPD be renewed?

ISO 14025 limits validity to five years. Renew sooner if the underlying PCR is updated or major plant changes shift GWP more than 10 % (ISO 14025, 2023).

Can I use one EPD for multiple manufacturing plants?

Yes, but each plant’s GWP must be reported separately within the same document so evaluators can match the specific facility supplying the project (EPA Interim Determination, 2022).

Beat GSA Clocks with Verified Low-Carbon EPDs

GSA’s low-embodied-carbon rulebook in 60 seconds

Congress gave GSA $2.15 billion to buy materials that beat strict global-warming-potential caps (GAO, 2025). To prove you qualify, the agency demands a product-specific, third-party verified Type III EPD rooted in the right PCR and less than five years old (GSA FAQ, 2025). Concrete, steel, flat glass, and asphalt top the shopping list.

Why “third-party verified” is non-negotiable

EPA’s Interim Determination makes verification the gatekeeper—no verifier stamp, no federal money (EPA, 2022). Facility data must replace industry averages wherever possible, so a mill-wide or plant-wide EPD kicks generic numbers to the curb. GSA contracting officers use that stamp as the quickest way to confirm compliance and move bids forward.

The calendar clash: 60-day awards vs six-month EPD cycles

GSA notes that most awards are made within 60 days of receipt of offers (GSA Bidding Guide, 2025). Meanwhile, Northwest manufacturers say a typical cradle-to-published EPD cycle lasts six to ten months (EPD Guide, 2025). That is an order-of-magnitude gap: the paperwork takes 4–5× longer than the bid clock.

Fast-track moves manufacturers control

Lock your PCR early. Picking the version used by rival products avoids redo work when specifiers benchmark GWPs.
Gather plant utility and mix data monthly, not at year-end, so numbers are ready for the LCA model.
Pre-book a verifier. Reputable programs often need three to four weeks’ lead time just to start a review (NRMCA, 2025).
Choose an LCA partner that shoulders data wrangling; your R&D team should be iterating mixes, not wrestling CSV files.

Common trip wires that stall submittals

Expired PCRs: a Version 1.0 that lapsed last quarter forces you back to square one.
Industry-average fallback: GWP caps are based on plant-specific performance, so average data flunks instantly.
Split facilities: a single EPD covering multiple plants must break out each site or GSA can’t gauge compliance. Thier bid reviewers do not have time for guesswork.
Late verification comments: every round of clarifications can eat a week—build float into your schedule.

Do the math: win rate beats up-front effort

GSA had obligated $767 million for low-carbon materials by January 2025—just 36 percent of its pot (GAO, 2025). The remaining majority will land on projects during 2026–2028. Even a modest five-percent share of that backlog equals $69 million in potential revenue for a ready supplier. Verification fees and data collection pale next to that upside.

Staying bid-ready every quarter

Keep your EPD library evergreen, update facility data annually, and track PCR expirations three months ahead. The prize is simple: when a 60-day solicitation drops, your submittal packet ships on Day 1 instead of Day 59—putting procurement angst in someone else’s inbox.
