The LCA dataset
Data ages. Producer-specific data must sit within five years, generic data within ten — beyond that it no longer represents the product.
EPD Validity & MaintenanceAn EPD is a verified fact.
An EPD is a verified fact.
Renewal is how it stays true.
Not paperwork at the end of a subscription — it's how a third-party verified declaration keeps meaning what it says after the data, product and rules behind it move.

Then it must be revised, re-verified and reissued.
Both are mandatory items declared on the EPD itself.
An EPD is not a marketing claim. It is a controlled, standardised document — and the most rigorous kind of environmental label there is.
“A standardised document reporting LCA results that complies with ISO 14025, a GPI and any applicable PCRs.”
Because it is a Type III declaration — quantified, built on a Life Cycle Assessment, and independently verified — every EPD is a verified statement of fact about a product at a point in time. That last phrase is the whole reason renewal exists.

Why it expires by designA declaration is only as true
A declaration is only as true
as the three things behind it.
By the rules of ISO 14025 / EN 15804 an EPD carries a built-in expiry — valid for at most five years, “after which the declaration must necessarily be revised and reissued.” It expires because none of these three stays frozen:
02
The product & process
A product or the way it is made can change — and the declared impacts change with it.
03
The reference PCR
The PCR is itself updated and can expire. A declaration on an old PCR no longer reflects the current rules.
So renewal means
Re-establishing it's still true

The same standard of proof as the original — a renewed EPD passes independent verification again, never merely re-dated.
The distinctionRenewal and recertification
Renewal and recertification
are two linked layers.
The words get used interchangeably. The program treats them as two things: one renews the document, the other renews the certification the document rides on.
Two layers,

Layer 1 · the document
EPD renewal
Layer 2 · the certification
Recertification
In one line
Revise, re-verify & reissue the EPD document so it stays a valid Type III declaration.
Renew the underlying Global GreenTag product certification the EPD rides on.
What it proves
The declared numbers are still accurate & PCR-compliant.
The product still “continues to meet” the requirements it was certified against.

EPDCERT
Kept in syncFor a certified product the EPD doesn't run on its own clock. It is reissued “in alignment with the renewal certification dates” — so the public declaration and the underlying certification are never out of step.
Verified, not re-dated
“Recertified” is a third-party re-attestation — never a self-declaration.
Renewal only means something because of independent verification — the same gate as first issue. To be published, an EPD must be successfully verified by a competent verifier, confirming the LCA data and that ISO 14025, EN 15804 and the GPI have been followed.

A change in the underlying data large enough to move any one declared parameter by ≥ 10% is, by definition, significant — and the EPD must be recalculated and verified.The owner carries sole liability to notify Global GreenTag.
