What DIY actually requires
Going in-house means someone on your team learns to use LCA software, correctly interprets and applies the relevant PCR, builds the model against your own primary data, and drafts the declaration for submission to a verifier. It's a real skill investment, not just a software subscription — the tooling handles calculation, not judgment calls about scope, boundary, and PCR interpretation.
What a full-service consultant provides
A consultant typically handles LCA modeling, PCR compliance, drafting, and often coordination with the verifier, working from primary data you still need to supply. You're paying for expertise and reduced risk of costly rework during verification, not for avoiding data collection entirely — that part is yours regardless of which path you choose.
Hybrid approaches
Software plus limited consulting support — for PCR interpretation, model review before submission, or verifier coordination specifically — is a middle path that's become more common, particularly for teams planning multiple EPDs who want to build internal capability without taking on 100% of the risk on a first attempt.
How to decide
Weigh how much internal LCA experience you already have, how many EPDs you expect to produce over time (one-off vs. ongoing program), your timeline flexibility, and budget. See Choosing an LCA Consultant or Software Platform for specific questions to ask whichever path you lean toward.
Frequently asked questions
Is DIY realistic for a first-time EPD?
It's possible, but the PCR-compliance learning curve is real — getting the functional unit, system boundary, and required impact categories right the first time without prior LCA experience is where most in-house first attempts run into trouble, usually surfacing as delays during verification rather than upfront.
Does outsourcing mean I have no visibility into the underlying data?
It shouldn't — a good full-service consultant still requires your primary production data and should be transparent about the model built from it, even though they handle the modeling and drafting work directly.
Which approach is more common for manufacturers producing many EPDs?
Manufacturers planning to produce EPDs across many product lines over time increasingly build internal capability via software plus targeted consulting support, rather than paying full-service fees repeatedly for each one — see Choosing an LCA Consultant or Software Platform.
