What Stonepeak just published
EC3 shows Stonepeak’s first current EPD covering porcelain stoneware ceramic slabs at 12 mm, published in November 2025 with the International EPD System as program operator (EPD International, 2025) (EPD International, 2025). The scope is a product‑family declaration for large‑format slabs made in Crossville, Tennessee, a fit for floors, walls, and fabricated surfaces.
Stonepeak’s own library now lists additional slab EPDs by thickness, including 6 mm and 8–9 mm, which signals a broader roll‑out across its U.S. slab portfolio (Stonepeak website, 2026). See their 12 mm library entry and recent news post for quick downloads (Stonepeak, 2026, Stonepeak News, 2026).
Who verified it
These EPDs were issued through the International EPD System, a program operator specifiers recognize across North America and Europe. For a plain‑English primer on that operator, see our field guide to the International EPD System. Public documents name Alfa Solutions as LCA practitioners on the Stonepeak files (EPD International, 2025).
Why this matters in specs
Think of a PCR as the rulebook of Monopoly, ignore it and the game falls apart. With product‑specific, third‑party‑verified EPDs in hand, project teams can model impacts without conservative penalties that often nudge non‑EPD products out of contention. The commercial effect is simple, less friction in bids, cleaner submittals, and fewer late‑stage substitutions when carbon accounting tightens.

Product and market context
Stonepeak manufactures porcelain tile and large‑format slabs in Crossville, Tennessee, serving commercial interiors, hospitality, multifamily, and fabricated surfaces. The EPDs land where designers already spec gauged panels for seamless looks and durability. That combination, U.S. production plus spec‑ready disclosures, plays well on public and private jobs that expect product‑specific EPDs tied to a declared site.
Competitive check, fast
Here is how the debut stacks up against brands buyers often weigh on the same schedules.
- Daltile lists several current, site‑specific tile EPDs valid to 2030 with the International EPD System. Their records name WAP Sustainability as developer on multiple entries (EPD International, 2025).
- Crossville shows lapsed tile EPDs in EC3 as of March 19, 2026, which means Stonepeak’s new coverage reduces avoidable submittal friction where product‑specific data is expected.
- Emser carries a current ceramic tiles EPD listed in EC3. Coverage is narrower than Daltile’s plant set, so Stonepeak’s slab‑focused EPDs are a timely counter in panel‑heavy specs.
Takeaway for bids, Stonepeak has moved from “good sustainability story” to “verifiable numbers” in the very formats that win modern finish packages.
Timing and findability
The first publication month is November 2025, and today is March 19, 2026. That gap is normal. There is often a lag of weeks to months between an operator issuing an EPD and that record appearing in the global tools specifiers actually search. Reducing that delay matters because every week without a findable listing invites substitutions. If future EPDs need to go live in directories within a day or two, reach out and we can share the playbook.
Where to point specifiers right now
Stonepeak has already posted EPD downloads in its site library and highlighted the rollout on its news page. That visibility is key. Keep them one click from product pages, add them to sustainability and resources hubs, and make sure sales teams can find them in seconds. If any product lines are still missing links, add them, since teams rarely hunt beyond a couple clicks to retrieve documents they expect to recieve on demand.
The bottom line
Stonepeak just put U.S.‑made porcelain slabs on the record with program‑listed EPDs. In a market where Daltile arrives with plant‑level coverage and others still juggle lapsed records, this debut makes Stonepeak more spec‑ready across commercial interiors and fabricated slab work. It is a confident first step, and it changes the competitive math in their favor.
