MDB Common Nature Finance Taxonomy

Overview & Synopsis

This Common Nature Finance Taxonomy was developed by Multilateral Development Banks (MDBs) to identify nature finance in their portfolios. As defined by the MDB Common Principles for Tracking Nature Finance (Version 2, 2025), nature finance is finance contributing to the nature positive goal of halting and reversing nature loss and supporting the implementation of the Kunming-Montreal Global Biodiversity Framework (GBF) through one or more of the following activity groups: (a) Restoration and conservation of biodiversity or ecosystem services; (b) Reduction of the direct drivers of biodiversity or ecosystem services loss; (c) Integration of nature-based solutions across economic sectors; and (d) Design and implementation of policy, tools, or other sectoral instruments enabling (a) to (c). This Taxonomy provides a standardized non-exhaustive reference list of activities that qualify as nature finance in sectors and cross-cutting themes with identified opportunities to contribute to the GBF goals and targets. In addition to covering a range of sectors, the Taxonomy covers different ecosystem types and regions, and is adapted to the development context in which MDBs operate. For a more detailed definition of nature finance and guidance on assessment, see the MDB Common Principles for Tracking Nature Finance.
