Primary Functions

  • Evaluate how credible and fit for purpose your organization’s natural capital assessments are.
  • Learn how to communicate and improve the level of confidence in your organization’s natural capital assessments.

Detailed Description


Natural Capital thinking helps organizations to make more informed decisions that conserve and enhance the natural capital we all depend upon. We therefore need confidence in the information produced by natural capital assessments.

The Natural Capital Checker (NatCap Checker) provides practitioners with a self-assessment tool that enables them to assess, communicate and improve the level of confidence in their natural capital assessments.

The Checker helps organizations to evaluate how credible and fit for purpose their assessments are, and therefore the level of confidence that stakeholders can place in the process, results, and ultimately the decisions taken based on a natural capital assessment

The NatCap Checker builds on assurance practice and the experience of those who have been applying natural capital approaches. It is aligned with the Natural Capital Protocol’s four Principles; Relevance, Rigor, Replicability and Consistency.

It is comprised of two parts; The Robustness Tool and The Maturity Tool.

The Robustness Tool

The Robustness Tool is the primary tool and enables users to assess, communicate and, if necessary, improve the robustness and therefore credibility of their natural capital assessment process and results.

The tool guides practitioners through a series of questions about their assessment, mapping the responses against the four Principles of the Natural Capital Protocol. It is important to acknowledge that the maximum level of confidence will not always be desired or appropriate, and this is reflected in the tool.

The Robustness Tool should be prepared by one person and validated by another.

  • ‘preparer’ – someone who has detailed knowledge of the natural capital assessment and can answer the questions such as what data was used and the valuation methods selected.
  • ‘validator’ – an independent party who can validate how the preparer has answered the questions and check that the principles have been applied.

The Maturity Tool

The Maturity Tool is a complimentary tool that allows users to assess how ‘mature’ an assessment is and to help to outline potential areas for next steps or blind spots (where robustness will need to be developed).
