This report identifies the availability and suitability of publicly available nature-related data to support financial decision-making in five case-study countries. Its findings and recommendations aim to inform data needs for successful disclosure frameworks, such as the Taskforce on Nature-related Financial Disclosures (TNFD), to be established. The challenges and recommendations are also of relevance for governments and data providers that would set the stage for a successful disclosure framework. The study has been developed by UNEP FI, UNDP and UNEP-WCMC.
