The Mark
of Integrity
We independently review sustainability claims for clarity, evidence, and regulatory alignment. Each reviewed sustainability report receives a Transparency Report and truMRK certification—giving your audience the confidence to trust what they read.

What is a truMRK?
A truMRK is a visible signal that your sustainability report has been independently assessed for transparency, responsibility, and communication quality.
Each truMRK links to a concise Transparency Report, combining expert review with AI-assisted analysis. We assess which claims were made, whether appropriate evidence was provided, the credibility of sources, and any risks or gaps.
We also check that language aligns with key guidance including the CMA’s Green Claims Code, ASA/CAP advertising standards, ISO 14021, and best-practice frameworks like GRI.
This isn’t about verifying performance data — it’s about ensuring your report communicates clearly, credibly, and in line with regulatory and stakeholder expectations.
WHY IT MATTERS:
✔ Stand out in a crowded ESG space
✔ Show due diligence and evidence-led thinking
✔ Reduce reputational and legal risk
✔ Stay ahead of regulatory scrutiny
✔ Publish a credible, independent view of your report
