Adaptation & Resilience
The impacts of climate change are already harming people and imposing costs on economies, with emerging markets and developing economies bearing the greatest burden. Floods, droughts, storms, and extreme heat upend lives, damage assets, disrupt supply chains, and strain public budgets.
In low- and lower-middle-income countries, GDP per capita is already an estimated 4% to 12% lower because of rising temperatures and sea levels (Grantham Research Institute, LSE, 2026). Climate adaptation is the process of adjusting to actual or expected climate impacts to limit harm. Resilience is the capacity that process builds: the ability to absorb shocks, recover, and keep functioning.
Strengthening the capacity of regions, countries, and companies to adapt and build resilience is therefore essential for protecting and strengthening macro-economic health. Examples of adaptation investments include climate-resilient infrastructure, flood and coastal protection, drought-resistant agriculture and improved irrigation, water storage and management systems, resilient power grids, and cooling solutions that protect people and assets from extreme heat.
The adaptation finance gap is large and growing. Current flows would need to increase by 12-14 times to meet developing countries’ needs (UNEP Adaptation Gap Report, 2025). While adaptation finance has grown in the past decade, more than 90% of global climate finance still goes towards mitigation (Climate Policy Initiative, 2025), which reduces emissions that drive climate change, rather than adaptation, which helps communities and economies manage impacts already being felt.
Adaptation and resilience investments are often harder to finance than energy investments, because their returns can be more challenging to quantify and attribute, while many of their benefits of these investments take longer to materialize. Financing adaptation and resilience demands decision-makers to invest now to avoid damage later, which requires forward-looking data on hazards, exposed assets and existing protections. Benefits rarely come through a single, predictable revenue stream, making the investment case more complex to build than most mitigation projects.
But adaptation can deliver strong economic returns, and financial institutions are already financing them. Resilience measures return a median of around four times their cost (Grantham Research Institute, LSE, 2026). In a 2026 GFANZ collection of 22 adaptation case studies, nearly half involved only private institutions using standard loans, bonds, equity and insurance. Where benefits are too dispersed or risks too high, concessional capital can help close the gap. Indeed, blended finance for adaptation rose 133% to USD 5.6 billion in 2025 (Convergence, 2026). Moreover, finance ministries and central banks are bringing physical climate risk into fiscal and macroeconomic planning, which can help bring more public and concessional capital to adaptation deals.
This section contains resources to help finance professionals, policymakers, educators and others build the understanding and skills to identify, assess and finance adaptation, from physical risk assessment and shared taxonomies and metrics to financing models that mobilise private capital for adaptation.
