What makes a sustainability commitment credible to customers?

Customers need to understand what an organisation is doing to fulfil its sustainability commitments, not simply hear another statement of ambition. Make the work behind each promise the substance of the account: explain what is being done and how it contributes to meeting the commitment. Sustainability involves hard work behind the scenes, and not every part of that work will be led by storytelling. The communication task is to make genuine effort understandable, rather than substitute a story for substance. An honest account also includes wins and failures as opportunities to learn. Organisations already working to improve their sustainability need to make that work visible, rather than leave customers with promises alone.

A sustainability initiative becomes meaningful to customers when its story explains its impact and learning, rather than simply describing the activity or technology involved. A blockchain initiative tracking a truck fleet's hydrogen-powered miles, for example, needs an account of what the initiative achieves and what the business learns from it. The technology alone is not the story. Include missteps where possible: learning from mistakes matters alongside reporting success, even when marketing and reporting requirements make failures difficult to discuss. Supporting claims also requires ongoing attention: the Competition and Markets Authority's 2026 claims-verification process calls for current supporting evidence, product composition and testing records, regular reviews, supplier updates and staff training. Pair the explanation of an initiative's impact with maintained support for the claims being made.
