The report sets out the results of 53 semi-structured interviews conducted between November 2019 and February 2020, with officers and elected members in selected local authorities in the Netherlands, Belgium, France and the UK, all with populations less than 550,000. The research aimed to support the development of a Business Model to help smaller municipalities to build a business case for Green Infrastructure (GI). It sought an understanding of funding and approval processes for GI project implementation, the obstacles that might obstruct GI development, and the use (or non-use) of tools intended to help these processes.
