The landscape of biodiversity financing is changing. Domestic and international financial flows have grown and the range of funding instruments, providers and delivery mechanisms available is much wider than ever before. This online "catalog" is a comprehensive list of these instruments, tools and strategies applicable to the field of biodiversity finance. Each entry in the catalog is a mechanism or "financing solution" and includes a brief description, as well as links to guidance material or case studies. The searchable catalog provides a list of all solutions presented. Solutions can also be searched by the financial outcome they produce, the financial instrument on which they are based, whether they are publicly or privately funded, and the economic sector in which they are most frequently used.
