Finance is now seen as one of the key challenges for the development and implementation of nature-based solutions in cities. While there is a growing interest in different forms of ‘green’ finance, there is a limited evidence base about how these resources can be leveraged to support nature-based solutions and the instruments and business models needed to support the financing of nature-based solutions. The NATURVATION project will examine both mainstream and innovative financial instruments and approaches in order to establish how nature-based solutions are currently being supported and explore the potential for new approaches.
