First-Party Assessment (Self-Declaration)
A conformity assessment performed by the organisation itself, with no independent second or third party involved.
Expert review openNo editor-accepted expert review yetDefinition
A first-party assessment is the demonstration that specified requirements are fulfilled, carried out by the person or organisation that provides the object of conformity — the supplier assessing itself. ISO/IEC 17000 defines conformity assessment generically as the demonstration that specified requirements relating to a product, process, system, person or body are fulfilled, and distinguishes assessment by the first party (the supplier), the second party (the customer or user) and the third party (a body independent of both). A self-declaration of conformity is the formal output of first-party assessment; it carries no independent verification.

Overview
What it means
First-party claims are legitimate and widely used — manufacturers' declarations of conformity underpin much product law — but their credibility rests entirely on the claimant's reputation and legal liability. In sustainability, self-declared claims (carbon neutral, deforestation-free) are exactly the category regulators now target with substantiation rules, pushing markets toward second- and third-party verification.
How it is used
Used in supplier questionnaires, internal audits, regulatory self-declarations and as the baseline tier in assurance hierarchies.
Why it matters
Distinguishing who performed an assessment is the quickest test of how much weight a sustainability claim deserves; much greenwashing is a first-party claim dressed as verification.

Review board
Comment on a specific line. Each reviewer stays separate until an editor accepts a merged draft.
Each person comments on the definition or overview in their own draft card, with role, evidence and suggested wording kept together.
AI can compare comments against the current text, flag conflicting claims, surface missing evidence and identify where reviewers agree.
An editor merges compatible suggestions into a draft change, checks sources, records disagreements and decides what can be published.
