Independent Transparency, Built for Trust
At truMRK, we believe that credible sustainability claims are the foundation of trust. Our independent verification service helps organisations publish clear, compliant, and evidence-backed communications – reducing the risk of greenwashing and making sure every claim can stand up to scrutiny.
We don’t measure performance – we measure how responsibly it’s communicated. Every reviewed report or communication earns a truMRK badge, linking to a public Transparency Report that outlines what was claimed, what evidence was provided, and where strengths, risks, or gaps remain. It’s a practical, trusted way to promote transparency and accountability.
Part of a Bigger Mission
truMRK was developed alongside The Anti-Greenwash Charter – a not-for-profit initiative championing responsible communication in sustainability. Together, we help businesses move beyond vague promises towards verified, meaningful progress.
We also continue the conversation through The Responsible Edge Podcast, where we speak with leaders across industries about embedding ethical, transparent practices into marketing, supply chains, governance, and more.
Why It Matters
Greenwashing erodes trust and undermines real progress toward sustainability goals. Stakeholders deserve clear, accurate, and well-evidenced claims. Organisations benefit when they communicate honestly, confidently, and in line with best practice.
truMRK provides the independent assurance that builds trust on both sides.
