This report provides an overview of existing and experimental financing mechanisms that can be used to encourage the conservation and sustainable use of biodiversity. To help to better understand these mechanisms, it proposes a taxonomy that divides the mechanisms into three categories: (i) those that protect biodiversity as a public good, (ii) those that require correcting so-called "negative externalities" that hamper biodiversity conservation, and (iii) those that can be used to support biodiversity-based businesses. The document ends with recommendations on how the Inter-American Development Bank can support financing mechanisms that promote the conservation of biodiversity and its sustainable use.
