State of Finance for Nature 2026

This annual report from the UN Environment Programme can help you understand the scale of financing needed to tackle climate, biodiversity, and land degradation-related challenges. It sets the scene and explains the status of current nature finance trends; provides an overview of global finance flows that contribute either to nature-negative outcomes or to nature-based solutions (NbS); and analyses the investments needed in NbS to meet Rio Convention targets, including limiting climate change to 1.5°C and reaching land degradation neutrality by 2030. It also introduces the Nature Transition X-Curve, a practical framework guiding governments and businesses to phase out harmful subsidies and destructive investments while scaling up high-integrity NbS across all economic sectors. These insights will be most useful to sustainability, finance, and strategy teams.
