In Karndean’s words

“Working with truMRK has been a highly valuable step in strengthening the way we communicate our sustainability work and to build on our commitment through the Anti Greenwash Charter. We used their independent Transparency Report as a benchmarking exercise for our 2024 Evolve Sustainability Report.

This gave us a clear, unfiltered view of the strengths in our approach, such as the clarity of our language and our commitment to recognised standards, as well as where we need to provide deeper context, clearer data, and more specific performance information for our stakeholder. And it has challenged us to think about our audience for future reports.”

The case study

01 / The challenge

Building confidence in published reporting

With expectations from regulators, customers and other stakeholders increasing, Karndean wanted to ensure its sustainability reporting was accurate, clear and balanced.

Having made a public commitment to responsible communication through the Anti-Greenwash Charter, the organisation sought an objective view of its reporting: where it was already strong, where more explanation was needed and how it could better meet its audiences’ needs.

02 / Why truMRK

An independent view, not an endorsement

Karndean commissioned truMRK to review its sustainability communications and produce a Transparency Report. The aim was to benchmark the reporting, rather than to certify the organisation or endorse its sustainability performance.

The review considered how claims were expressed and supported, whether the language was proportionate, and whether readers had enough context to understand the information presented.

03 / The approach

Testing the report from the outside

After publishing its 2024 Evolve Sustainability Report, Karndean used the independent assessment to challenge internal assumptions and see the content from a stakeholder’s perspective.

The findings covered:

  • Clarity and precision of sustainability language
  • Where further context would help understanding
  • How performance data could be more specific
  • How well the report addressed different audiences
04 / The outcome

Practical findings for the next reporting cycle

The assessment highlighted strengths in the clarity of Karndean’s language and its commitment to recognised standards. It also identified opportunities to provide deeper context, clearer data and more specific performance information.

Those findings have helped the team reconsider what different audiences need from its sustainability reporting and have informed planning for subsequent reports.

05 / Looking ahead

Bringing review earlier into the process

Following the initial Transparency Report, Karndean began developing its next sustainability report with truMRK involved earlier in the process. The intention is to support clearer, better-substantiated communications before publication, rather than relying only on a retrospective review.

This case study concerns the independent review of Karndean Designflooring’s 2024 Evolve Sustainability Report. It is separate from any review of the organisation’s 2025 Sustainability Report.
