We performed in-depth research of 20 international best practices of innovative adaptation funding and financing solutions (AFFS). Each case offers an inspirational example of successfully raising financial resources for climate adaptation or other climate measures. We analysed the local context, the governance and organisational structure, the business model and financial model, successes and limitations, and conditions for transferability. Being a best practice from a financial perspective does not guarantee the cases are a best practice from other perspectives (e.g., justice or socio-economic impacts). We advise to read the ‘Methodology and lessons learned’ report for a description of the research methodology and limitations, and a comparative analysis of successes and limitations in the 20 best practices. The reports on this page are complementary to Deliverable 1.1: Adaptation Investment Landscape. The complete best practice reports and the methodology and lessons learned report can be downloaded from this page.
