There are an increasing number of tools available that aim to value green infrastructure. Many of these focus on specific services provided by the green infrastructure and estimate the economic value of these services.
This report was commissioned to draw together a number of the most widely used tools and assess them against research standards for natural science and economics. The aim is to help people wanting to value green infrastructure choose the best tool for them. As well as descriptions and the assessment of the tools, links to further information and examples of the use of the tools are provided. The report also points to the key gaps in the tools available highlighting areas for further work.
