The Paulson Institute estimated in 2020 that the biodiversity financing gap at an average of US$711 billion per year. Government leaders and private enterprises must accelerate and scale financial resource mobilization strategies to close this gap. However, at a national level, many developing countries have limited market access and lack the fiscal space to mobilize financing at the scale required to avoid the severe negative impacts of biodiversity loss, nature degradation, and reduced ecosystem services. This can precipitate countries into a vicious circle, whereby delayed investment at scale exposes them to the risk of ecosystems collapse. These systems also provide essential climate benefits in terms of carbon sinks and adaptation buffers against severe climate impacts (e.g., floods, droughts, storms). These natural assets underpin economic growth of developing countries but are currently undervalued and underinvested. Given the difficulty of estimating the timing, progression, and extent of these impacts and their global public good (GPG) nature, other more immediate or visible needs tend to be prioritized. However, when nature-related risks materialize, economic activity is likely to contract, further reducing fiscal space, increasing a country’s borrowing costs, and delaying investments.en-USCC BY-NC 3.0 IGOCLIMATE AND NATURE INVESTMENTBIODIVERSITYFINANCING GAPPUBLIC AND PRIVATE FINANCINGBriefWorld Bank10.1596/40228
