Welcome to Tool Assessor

What is Tool Assessor?

Tool assessor is a free service that provides summary information about ways that show the value of the natural environment in society. This value includes, for example, the role of natural features in reducing flood risk, improving health and storing carbon.

Tool Assessor is provided by the Ecosystems Knowledge Network to:

  • help people understand what methods and tools are available; and
  • enable people developing and using these tools to share information about them.​

Across the UK, the networks of features that provide these benefits are sometimes referred to as natural capitalnatural assetsgreen infrastructure and green networks. The contributions that these features make to people's lives are often called ecosystem services.  Many of the tools profiled in Tool Assessor use these terms.

Tool Assessor Project development

The latest revision of Tool Assessor (January - March 2021) was kindly funded by Defra. A review of the initial 12 tools in 2015 was funded by the Joint Nature Conservation Committee - the project report can be downloaded from the JNCC website. NERC funded an Innovation Internship (Alison Smith of the Environmental Change Institute at the University of Oxford) to revise entries in Tool Assessor in 2017 and raise awareness of tools with potential users (grant reference NE/P01254X/1).

Tool Assessor is a free service.
