According to the 2023 UN Adaptation Gap Report, the annual climate adaptation financing gap in developing countries is estimated to be between USD194-366 billion, approximately 10-18 times more than current financing flows. Although investors increasingly recognize the opportunities for investments to cope with the risks and impacts of climate change, private investment towards adaptation and resilience is still hindered by the lack of clear, practical, and investor-relevant metrics.
In response to these challenges, this report provides a clear, consistent, and robust framework for measuring the impact of investments on climate adaptation and resilience. Designed for development finance institutions, multilateral development banks, and impact investors, the report demonstrates how the metrics framework can be embedded in the investment cycle and outlines a set of impact metrics examples that can be used for individual investments or aggregated across portfolios.
