A sustainability consultancy built on standards, not slogans
ViridisPride is a UK-based consultancy specialising in Life Cycle Assessment, Environmental Product Declarations and independent EPD verification.
How we think about the work
We are science-led. Every assessment starts from a clearly defined goal and system boundary, is built on primary data wherever it can be obtained, and follows the relevant ISO and EN standards to the letter. We document our assumptions so the work is reproducible and defensible.
We are independent by design. Our EPD verification and LCA critical review work is kept conflict-free: we do not verify declarations we prepared. That separation is what makes the result credible, and it is something a tool that generates and signs off its own output cannot offer.
We are people, not a portal. Clients work with a named consultant who understands their product, their sector and the standard they need to satisfy, and who is accountable for the quality of the work.
Our principles
Environmental claims should be defensible.
Every number we publish should survive a hostile review.
Standards are not paperwork.
They are the reason a procurement team in Berlin can trust a declaration written in London.
Independence is structural, not promised.
Verification work is separated from consultancy work by design.
