Why sustainability language converged industry-wide

Open the responsibility sections of twelve companies in unrelated industries and the phrasing is interchangeable: commitments, pathways, materiality, stakeholder engagement. The operations behind those pages differ enormously. The pages do not, because they are all addressed to the same small set of readers.

What everyone sees

Uniform language is read as evidence that an industry has genuinely aligned on standards, or alternatively dismissed as coordinated cynicism. Neither requires coordination. Independent firms responding to identical rating frameworks, disclosure regimes and institutional investors will converge on identical vocabulary without a single meeting between them.

What is actually happening

DiMaggio and Powell described institutional isomorphism, in which organisations facing the same environment come to resemble one another through coercive pressure from regulators, mimetic copying under uncertainty and normative pressure from professional communities — producing similarity in form regardless of similarity in performance. Meyer and Rowan added that adopting legitimated formal structures can be loosely coupled to what the organisation actually does, because the structures are addressed to external audiences. Lyon and Montgomery’s review of greenwash documents the resulting gap directly, along with the measurement problem: the language is standardised, verification is uneven, and disclosure quality correlates only weakly with outcomes. Convergence is therefore informative about the audience and close to uninformative about the practice.

Why it stays hidden

The gap hides because standardised language is easier to compare than practice, so analysts compare it. A vocabulary designed for legibility to raters becomes the material everyone assesses, and firms that write in the standard register score well on the standard register. The measurement problem is invisible because the measurement instrument is the text.
