truMRK explained

truMRK is an independent third-party verification service for sustainability communications. We assess reports, campaigns and other content against published criteria for Claims, Language and Context. The aim is to help organisations strengthen their communications before publication and demonstrate when their content has met our standard.

We review sustainability and ESG reports, campaigns, corporate websites, investor communications, press releases and other public-facing material that makes sustainability-related claims. The scope is agreed before the assessment begins.

No. truMRK verifies whether the communications reviewed meet its published assessment criteria. We examine the evidence presented in support of claims, the language used and the context provided. This is not a certification of the organisation or independent verification of its underlying environmental or social performance.

As scrutiny of sustainability communications grows, organisations face greater pressure to substantiate claims and communicate transparently. An independent review can identify weaknesses before publication and provide stakeholders with a clearer account of how the content has been assessed.

Claims considers whether statements are supported by credible, relevant evidence and clearly explained assumptions. Language examines whether wording is clear, proportionate and potentially misleading. Context considers whether material issues, limitations and challenges are presented fairly. Explore our methodology.

Each area receives a separate score on a 1–100 scale. The content must score at least 60/100 in each of Claims, Language and Context to meet truMRK’s published requirements. A strong score in one area cannot compensate for a score below the threshold in another. Understand the assessment scores.

Our bespoke AI-powered assessment tool supports a consistent, structured analysis of the submitted content and evidence. Expert human reviewers then examine the findings, apply professional judgement and oversee the final assessment. AI supports the process; it does not replace expert review.

Timescales depend on the length and complexity of the content, the quality of the supporting evidence and any issues that need addressing. Our combination of bespoke AI analysis and expert human review helps us work efficiently and plan assessments around publication deadlines wherever practical. We agree a realistic timetable at the outset rather than promising a fixed turnaround for every project.

We provide findings and recommendations to help organisations strengthen claims, wording and context. The organisation remains responsible for making changes and approving its own communications. truMRK retains independence in its assessment of the revised content.

The mark may be displayed only when the content reviewed has achieved a PASSED result in all three areas: Claims, Language and Context, with a score of at least 60/100 in each. The mark links to a public truMRK Transparency Report confirming the outcome and explaining the scope of the review.

It means the specific content reviewed has met truMRK’s published scoring thresholds across Claims, Language and Context. It does not mean that the organisation’s overall sustainability performance, or every statement it makes elsewhere, has been independently verified.

It is a public summary confirming that the content has achieved a PASSED result across all three assessment areas. It identifies the content and scope reviewed, relevant limitations and noteworthy examples of transparent disclosure, including where an organisation openly acknowledges challenges, limitations or areas needing improvement. The public summary does not need to reproduce every detailed assessment score. View an example Transparency Report.

We provide feedback identifying where the content falls short, so the organisation can address the issues and submit revised material for reassessment. The truMRK mark cannot be displayed unless all three thresholds are met. The scope, timing and any additional fees for reassessment are agreed for the project.

No. An organisation can use the findings privately to improve its communications. Publication of an unsuccessful assessment is not required. However, the truMRK mark and accompanying public Transparency Report are available only for content that meets the published thresholds.
