Three sentences from the field
Sound familiar?
“We thought an EPD was a certificate”
Many companies assume an EPD declares their product “green”. An EPD is not an endorsement — it is a transparent declaration. If that expectation is not corrected at the start, the process ends in disappointment.
“We've been stuck in verification for months”
Comment, revision, another comment... As verification loops multiply, the timeline stretches. The problem usually starts not in verification, but in data collected months earlier.
“Our data is scattered — where do we start?”
Energy invoices in one place, recipes in another, waste records missing. The least predictable part of the process is not verification — it is data collection.
We hear these three sentences on projects of every size. All three have the same cure: starting the process through a verifier's eyes.
The solution
We answer verification questions before they are asked
From data collection templates to allocation decisions, from background data selection to end-of-life scenarios — every step of the study is built knowing what will be scrutinised at the verifier's desk. Revision loops shrink; the timeline becomes predictable.

What the market demands — and the answer
An EPD is no longer “nice to have” — it is the common denominator of exports, tenders and the incoming regulatory wave.
From someone who knows both sides of the process
Hello, I'm İpek. I have been working with EPD, LCA and sustainable building products for over 14 years. Throughout my career I have sat on both sides — preparing EPDs and verifying them independently. And I have seen this: the cause of a weak EPD is almost never the verification itself, but the data decisions made months earlier. I founded EPDlogy so that manufacturers can run this process in a way that is clearer, more controlled and verification-ready from day one.

Frequently Asked Questions
Everything you need to know about EPD verification and LCA consultancy.
What is EPD verification?
EPD verification is a mandatory independent review of an EPD before it can be published. A qualified third-party verifier checks that the LCA model, data, assumptions and report comply with the relevant PCR and EN 15804+A2.
How long does EPD verification take?
Typically 2–4 weeks, depending on the complexity of the product and the completeness of the documentation submitted. Clean, well-prepared studies move fastest.
Which EPD programmes do you verify for?
The International EPD® System, EPD Hub, EPD Global and Building Information Foundation RTS (Finland).
What is the difference between EPD preparation and EPD verification?
EPD preparation involves conducting the LCA and writing the EPD report. EPD verification is the independent review of that report by a qualified third party before publication. EPDlogy offers both — but never for the same project, to preserve verifier independence.
What product types can you verify?
Steel, aluminium, concrete, insulation, facade systems, windows, flooring, ceiling systems, furniture, plastics, paints and more. Experience across a wide range of construction product categories.
