Designed to give organisations an overview +of their sustainability maturity across six themes, highlighting strengths, development priorities and recommended next steps.

Leeds (UK), 4th November 2026 – Tunley Environmental has launched a new Sustainability Maturity Assessment to help organisations understand the maturity of their current approach and identify implementable priorities for further development.

Sustainability responsibilities span across business strategy, operational performance, supply chains, customer requests for data and reporting requirements. However, organisations can find it difficult to bring these areas together, assess progress consistently and decide which priorities should come next.

Tunley Environmental’s assessment provides a structured starting point. Respondents answer questions about existing activities and systems, and their responses are scored across business strategy, carbon, circularity, water, nature, and compliance and reporting.

The assessment provides:

  • An overall percentage score and maturity level of Basic, Developing, Established or Leading
  • Individual scores and maturity ratings across all six sustainability themes
  • An overview of the organisation’s highest-scoring theme and greatest scope for development
  • Three strengths, grounded in the organisation’s submitted answers
  • Three priority gaps with corresponding recommended actions
  • Relevant services where specialist support may be useful
  • A personalised report, signed off my Tunley’s scientists, designed to support internal discussion and planning

The questionnaire also recognises when an answer is uncertain or unverified, helping organisations distinguish between activity that has not been undertaken and information that still needs to be confirmed. Recommendations are mapped to the submitted responses so that the resulting action plan remains proportionate to the organisation’s current position.

Commenting on the launch, Dr William Beer, CEO & Founder at Tunley Environmental said:

“Businesses often know that sustainability is important but can struggle to see where their current approach is strongest and where limited time and resources should be focused next. The Sustainability Maturity Assessment is designed to give them a structured starting point.”

“By bringing strategy, carbon, circularity, water, nature and compliance together in one report, the assessment helps organisations work towards prioritised initiatives that reflect their organisation’s sustainability requirements.”

The assessment is a diagnostic of organisational maturity rather than an audit, certification or independent verification exercise. Its score reflects the submitted responses and should not be treated as a direct measure of environmental performance, legal compliance or achieved impact.

Organisations can use the personalised report to support internal conversations, compare progress across themes and consider which actions are most relevant to customer expectations, reporting needs, existing targets and available team capacity. Where further support is needed, Tunley scientists can discuss suitable next steps separately.
