Turning avoided loss into financial gain

Valuing investments in adaptation and resilience

1. Context

With physical climate risks mounting, the need for adaptation2 - to a warmer climate, increasingly frequent and severe natural disasters, and consequences for society - is front and centre. Households, companies and governments need to factor escalating physical climate risk into consumption, business and operational strategy and capital investment, including climate damage to asset values, climate-related business interruptions and the cost of risk reduction.

Many studies document that investments in adaptation which preserve the value of financial and physical assets benefit both businesses and society at large.3 It follows that efficient markets should reward adaptation measures that reduce the overall risk profile of assets or entities, for instance, through improved access to capital, lower borrowing and insuring costs or higher market valuations. However, while the economic benefits of adaptation are clear, quantifying them - and reflecting added value in market pricing - remains challenging. While some studies suggest that financial markets are more systematically pricing climate risks4 (including outside the insurance sector, where climate risk pricing is most advanced), the benefits of adaptation measures are still not well recognised.

In the face of increasing physical risks, systematically recognising the value of risk reduction - in short, turning avoided losses into financial gain - could significantly influence how adaptation is valued across the economy, and within financial markets. This paper examines the factors that are constraining this shift, and explores the policy, market, and regulatory solutions that could help catalyse private capital for adaptation and resilience. A brief overview of adaptation and resilience investment concepts is provided in Annex 1. Section 2 describes the challenges in factoring adaptation into market pricing and asset valuation. Section 3 discusses what would be needed for adaptation measures to be more systematically valued across the economy and financial markets, looking across: (1) real economy policy frameworks; (2) financial market practices in the insurance sector; (3) financial market practices in the banking sector; and (4) de-risking, including public insurance mechanisms and blended finance. Section 4 draws conclusions and sets out priorities for action.

2. Why aren’t the economic benefits of adaptation fully priced into financial markets?

There are several factors that affect how adaptation is being factored into market pricing and valuation. These can be considered under two broad themes: real economy valuation barriers that affect investment decision-making by firms, households, and governments; and structural constraints within the financial system that impede the translation of risk reduction benefits into financial variables. Encouragingly, innovations in data, modelling, product design, and policy are beginning to address these gaps - and several of the issues set out below have corresponding solutions discussed in Section 3.

Theme A: Real economy factors

The benefits of adaptation are not consistently valued across the real economy, and can be difficult to quantify. Furthermore, the core characteristics of adaptation and resilience actions - including upfront costs, uncertainty regarding future benefits, and exposure to others’ decisions - can create disincentives to invest. Key issues include:

Value preservation vs. generation: Adaptation measures reduce exposure to risk and maintain the value of assets over time - but typically impose near-term costs without a clear or immediate link to revenue generation. Compared with investments designed to drive near-term business growth, adaptation investments are more difficult to justify: the benefits are uncertain, long-dated, and conditional on climate risk materialising. In contrast, measures that more directly contribute to tangible business value preservation - such as insurance coverage - may be more readily factored into business decision-making. The evolving physical climate risk context means that the value of insurance is becoming more explicit in longer- as well as short-term decision-making; for example, awareness that assets might become uninsurable over the medium term can have ‘up front’ implications for investors’ risk appetite, affecting access to capital. Addressing this challenge requires enhancing corporates’ understanding of the links between physical risk profiles and their trajectories, implications for insurance availability and costs, and mechanisms for recognising and pricing the risk-reduction benefits.

Risk pricing and transmission: Insurance provides a price for risk exposure within the economy, and quantifies the cost of inaction arising from a lack of adaptation or resilience investment. However, the annual repricing cycle of insurance contracts creates a structural mismatch: while the trajectory of physical climate risk is rising, individual policyholders face discrete annual pricing decisions and may systematically underestimate the rate at which risks - and therefore insurance costs and availability of cover - will change over the life of an asset or investment.6

Uncertainties affecting return on investment: The benefits of adaptation measures are uncertain, and can be difficult to evaluate for some real economy actors. Robust cost-benefit analysis requires the consideration of an array of subjective choices, including baselines, discount rates, and integration of non-market benefits.7 In aggregate, however, the costs of adaptation can be modest relative to the losses they can avert - and from this perspective, make good business sense. Evidence across multiple sectors consistently shows benefit-cost ratios for adaptation investments in the range of 2:1 to 10:1.8 Recent analysis by the UK Climate Change Committee estimates that adaptation investment of around £11 billion per year (range £7-22 billion, 2025 prices) is needed from the public and private sectors, against climate costs to public welfare of 1-5% of UK GDP by 2050 under 2°C of global warming, equivalent to £60-260 billion per year.9 There is strong evidence in certain sectors (e.g. renewable energy and infrastructure) of material benefits accruing from resilience measures being taken as part of project planning and implementation, of more than six times upfront costs.10 However, for some investments - including those which are ‘public good’ in nature - aggregate benefits can accrue diffusely, over long timeframes, and often to parties other than those bearing the upfront investment costs. Furthermore, in the absence of significant physical impacts, or when losses from events are less significant than expected, the return on investment from adaptation measures may be lower than projected. Strengthening resilience in certain systems, such as supply chains, may also be made more complex due to other economic imperatives (see Box 2).

Third-party impacts and contingencies: Adaptation is an iterative process, and the return on any individual investment depends partly on factors outside the investor’s control - including the choices of neighbouring actors, network infrastructure providers, and public authorities. Given uncertainty about the timing and severity of future climate events, and the often irreversible nature of adaptation measures, economic actors face a genuine trade-off with respect to the optimal moment to invest, and can gain option value by delaying, particularly where technology may make measures cheaper over time.13 This creates a structural ‘first-mover disincentive’: actors that delay can benefit from the actions of others, while early movers bear upfront costs and uncertainty. Overcoming this dynamic requires coordination mechanisms and, in some contexts, regulatory requirements that align the incentives of interdependent actors.

New build and retrofit: The investment economics of adaptation differ between new build and retrofit of existing assets. For new build, the additional cost of constructing to resilient standards is typically modest relative to total project cost, and can be embedded in financial models as a forward-looking reduction in expected loss, making the business case relatively tractable. Retrofit presents a more complex valuation challenge: upfront costs are higher, residual risk reduction is less certain, and the counterfactual - what losses would have occurred in the absence of the measure - is inherently difficult to observe. Financial instruments that explicitly recognise the improved risk profile of retrofitted assets, such as resilience-linked credit facilities and insurance structures with risk-reduction KPIs, remain underdeveloped and represent an important frontier for product innovation.

Context specificity: Adaptation is highly context-specific, responding to local hazards, levels of exposure, and vulnerability factors - and adaptation needs may shift over time in response to climate change.14 Several studies have explored the range of adaptation measures that can be implemented across sectors and geographies.15 Some international standards relating to adaptation, including those developed by ISO,16 are available. However, there is not a consistent overarching set of national or global standards for what an ‘adapted’ asset or entity looks like, in terms of the measures taken to achieve a certain level of resilience to a given hazard. While the absence of consistent standards compounds the valuation challenge, comparable data on loss avoidance - much of which already exists within the insurance sector - could in many cases provide a more tractable near-term basis for recognising adaptation value.

Theme B: Financial system factors

The valuation challenges facing real economy actors are compounded by structural barriers within the financial system that make it difficult to translate risk reduction into financial variables - including a lack of visibility, attribution challenges, and portfolio and macro-level factors. Several issues are key:

Lack of visibility of avoided losses as a counterfactual: The economic benefits of adaptation measures are not directly identifiable in historical loss data on which financial risk models are based, as such data capture realised losses rather than counterfactual outcomes.19 This contributes to a systematic under-recognition of the risk-reducing effect of resilience measures within markets.20

Attribution and translation into financial variables: The implications of economic losses - and the visibility of their impacts across portfolios - may vary significantly across financial institutions, depending on their business models and levels of exposure. For insurers, climate-related economic losses are immediately visible in property and casualty (P&C) loss data. Certain risk models, including natural catastrophe (Nat Cat) models used in the insurance sector, may be best suited to integrating risk reduction measures.21 However, the reflection of risk reduction in other types of models - including credit risk models - may face greater challenges. One overarching issue is the need to differentiate assessment of first-order physical risk to the economy (e.g. in terms of the exposure of borrowers and financed assets), and the assessment of factors which translate into credit risk evaluation - including capacity to repay, collateral value, and probability of default.22 Further issues stem from the challenge of clearly delineating climate risk factors as drivers of the broader suite of risks affecting borrowers.23 Analysis indicates that the direct, system-wide impacts of climate change on bank credit quality have so far been comparatively limited.24 However, this finding should not be taken solely at face value - as it also reflects the methodological challenges inherent in attributing changes in borrower risk profiles to climate risk vs. other factors - as well as the challenge of integrating wide-ranging and diffuse phenomena into specific financial risk variables. This challenge attests to the need to expand the use of insurance sector data to inform assessments of physical risk exposure at the asset level as an input to the credit risk assessment process. Recognising the differences between the suitability of different types of risk models for climate-related physical risk assessment (e.g. Nat Cat, underwriting risk, credit risk, etc.) is an important step towards designing an effective supervisory response - and ensuring that focus is placed on reducing underlying sources of risk, rather than solely their financial system impacts.

Asset- vs. portfolio-level change: A significant share of the increase in climate-related economic losses reflects higher exposure to climate hazards, due to choices to build and invest in higher-risk areas. While adaptation measures can reduce the vulnerability of individual assets, their impact at the portfolio level may be outweighed if overall exposure continues to grow.

Separating market signals: The benefits of adaptation measures can be difficult to disentangle from other factors affecting the pricing of financial assets. In both the insurance and banking sectors, the impact of traditional macro variables is generally far greater than the benefit of any adaptation measure. As such, the positive impacts of adaptation actions on risk profiles may be overwhelmed by more significant non-climate risk factors, such as high debt levels and constrained fiscal space.25

Financial regulatory considerations: Regulatory frameworks for financial institutions have only limited capacity to reflect changes in risk profiles stemming from adaptation measures taken by clients and counterparties. Within the banking sector, the Basel framework focuses on credit, market, operational, and liquidity risks over near-term timeframes.26 In insurance, climate risk is primarily captured through underwriting and catastrophe modelling approaches, which can in part reflect adaptation measures, although these effects may not be fully or consistently integrated in prudential metrics. More broadly, given their design, time horizons, and underlying tools, prudential frameworks are not well suited to capturing globally systemic and forward-looking phenomena such as climate change.27 Nonetheless, debate on the use of different types of microprudential and macroprudential tools to respond to climate risks continues, now with more focus being placed on physical climate risks. At the same time, supervisors and regulators continue to explore options to address adaptation issues, including in the context of financial sector transition plans. Further implications are discussed in Box 4 in Section 3.3.

3. What would be needed for adaptation measures to be more systematically valued across the economy and financial markets?

Adaptation measures should be much more systematically valued within the economy - and the losses avoided as a result of such measures be made visible within financial markets. Promising innovations are emerging, driven by technological developments and growing engagement from financial institutions, standard-setters, and policymakers. Notable gaps remain - especially in terms of policy, data, and market architecture - but the trajectory is encouraging. Efforts to make adaptation measures visible would require increased coordination and engagement across corporates, financial institutions, policymakers and regulators.

3.1 Policy frameworks

Regulatory requirements and resilience standards: Many jurisdictions set regulations and standards that mandate the level of resilience to physical damage that assets such as buildings and infrastructure must meet. Where such standards are appropriately forward-looking and account for escalating levels of physical risk intensity or frequency, they can effectively require asset owners and project developers to internalise the value of future adaptation benefits into overall project capex. Where such standards require retroactive modifications to be made to existing assets, governments can provide an array of incentives and fiscal mechanisms (e.g. tax incentives, grants) which can then serve as the basis for the structuring of private finance solutions (e.g. credit products to support resilience investments). However, such standards vary significantly across jurisdictions, depending on the existing state of infrastructure, the range of hazards within a jurisdiction, and the types of solutions that are needed to strengthen resilience. To be effective, such standards need to be concrete and operationally specific - for example, building codes and planning requirements mandating climate-resilient design for new construction, permitting requirements conditioning development approval on resilience criteria, and procurement requirements for public infrastructure in exposed sectors such as agriculture, energy, logistics, and manufacturing.

Several jurisdictions have established reference models for how sector-level resilience standards can be operationalised. The Netherlands’ Delta Programme sets legally binding flood protection standards linked to specific hazard return periods across its territory, backed by a dedicated investment programme.28 In the United States, FEMA’s Building Resilient Infrastructure and Communities (BRIC) programme provides competitive mitigation grants for certain types of infrastructure projects, and the National Flood Insurance Program (NFIP) Community Rating System links flood insurance premium discounts to community-level resilience measures.29 The EU Strategy on Adaptation to Climate Change30 provides an overarching cross-sectoral policy framework that supports member state adoption of sector-specific standards, while other jurisdictions - such as Australia31 and Singapore32 - have implemented frameworks for resilience assessment and funding mechanisms for risk reduction. The UK Climate Change Committee’s Fourth Independent Assessment of UK Climate Risk (CCRA4-IA) represents a leading example of how sector-level resilience objectives can be translated into quantifiable, time-bound targets.33 National Adaptation Plans, sectoral resilience strategies and project preparation mechanisms can help translate adaptation needs into investable pipelines, improve project bankability and provide greater visibility to private investors on future adaptation financing opportunities.

Beyond setting standards or regulatory mandates for resilience, policymakers face a temporal challenge in seeking to incentivise the most efficient response across the economy. From this perspective, policymaking for adaptation should place equal focus on addressing key coordination challenges (e.g. multi-stakeholder engagement across ‘beneficiary’ groups), in addition to ensuring that standards reflect the evolving profiles of climate-related risks.

In some key sectors - such as agriculture or water management - a lack of effective adaptation may have systemic consequences, yet there may be structural barriers that affect investability. Even where economic value may be visible (e.g. due to externalities being priced), projects may not be readily investable without changes to market architecture - including clearly defined payment structures, mechanisms to translate economic value into cash flows, and verification systems.34

Strengthening national standards and plans: National Adaptation Plans (NAPs) represent the principal international framework through which countries are expected to develop adaptation strategies and establish monitoring frameworks.35 However, the substantive integration of sector-level resilience thresholds - referenced to specific hazard return periods or performance standards - remains limited in most submitted NAPs. Most NAPs identify key sectors of concern but stop short of specifying operational standards against which adaptation progress can be measured. The more tractable objective is for NAPs to incorporate clear, sector-specific resilience thresholds at the national level, supported by guidance from bodies such as the World Bank, World Meteorological Organization, and IPCC. Where sector standards have been established and clearly linked to insurance conditions, market participants are better positioned to develop targeted financing solutions.

Aligning the costs and benefits of adaptation measures: As described above, adaptation investments that are inherently public in nature deliver benefits to a broad range of economic actors and stakeholders. Measures that link the costs of such investments more clearly to beneficiaries could help strengthen the visibility of adaptation measures for these stakeholders (e.g. homeowners benefiting from seawall investments). A number of innovative approaches are being explored to generate revenue streams from public investments in adaptation, including tariff- or user-fee-backed models employed by utilities, and outcome-based contracts.36 Developing new market architecture to create a consistent ‘line of sight’ from economic to financial value stands as a key research and collaboration priority.

Better availability of data and insights: In order for the value of adaptation measures to be effectively quantified, comparisons need to be made between ex-ante and ex-post states - requiring reliable data on climate exposure, and actions taken to reduce risks. Some financial institutions report that clients are increasingly bringing information on adaptation measures, and forward-looking climate resilience plans, into commercial processes. To be meaningful from a risk pricing perspective, such actions need to be translatable into risk management processes, models, and metrics that are relevant for financial institutions. However, information is not often provided in a consistent way, requiring subjective judgements on the relative impact of a given action on a client’s overall risk profile.37 Greater transparency and consistency in the structuring of client information on exposures and resilience actions would in turn support financial institutions in incorporating this information into their own analyses.

Fiscal incentives for adaptation investment: Fiscal incentives can play an important role in bridging the gap between the economic benefits of adaptation investment and the financial returns available to individual actors. Options include tax credits for adaptation capital expenditure, accelerated depreciation allowances for climate-resilient construction and retrofits, concessional financing windows for resilient housing and infrastructure, and outcome-based grants tied to demonstrated resilience improvements. Drawing on experience from energy efficiency and clean energy policy, where fiscal incentives have materially catalysed private investment, analogous mechanisms can be designed for adaptation contexts.38 In many jurisdictions, existing fiscal frameworks were not designed with adaptation investment in mind, and gaps in eligibility criteria, additionality requirements, and verification mechanisms may limit the direct application of models developed in the clean energy context.

3.2 Financial market practices, instruments, and policies - insurance sector

Risk modelling and contract structures: The financial system provides a broad array of products and solutions through which adaptation measures taken by clients are gradually reflected as value-preserving benefits, and rewarded through pricing. The architecture of risk models - particularly in the insurance sector, where actuarial models still rely heavily on historical loss data - is structurally designed to assess the impact of risk profiles in response to different risk drivers. In the absence of structural integration into risk models, adaptation measures can be integrated into financial sector contract structures - yet this requires targeted identification of such actions (e.g. in the form of quantifiable KPIs), as well as scenarios and climate projections. Many financial institutions are actively innovating to address these challenges.39

Impacts of adaptation on insurance pricing: Adaptation investment affects not only today’s insurance premium but the future trajectory of insurance availability and affordability. As physical climate risk increases, the range of perils and locations for which insurance is available at economically affordable rates may narrow. Adaptation measures - whether undertaken by policyholders or by governments through infrastructure investment and land-use planning - can therefore help to maintain insurability by keeping expected losses and loss volatility within commercially viable bounds. Where insurance pricing appropriately reflects underlying risk trends, it also serves as a forward-looking signal to economic actors, highlighting the cost of inadequate adaptation. Against this backdrop, public and private insurance programmes increasingly act as resilience engines - reinforcing risk prevention, strengthening incentives for adaptation, and supporting faster recovery while reducing pressure on public budgets.

Insurers are also playing a critical role in helping to raise awareness about risks, identify adaptation and resilience investment options, and support implementation. Some insurers are developing multi-hazard portfolio advisory capabilities that allow clients to systematically identify adaptation priorities and quantify risk reduction potential across their asset base.40 Other firms are expanding risk consulting service offerings, to support clients in identifying and targeting resilience measures. These advisory services operate independently of underwriting relationships and can provide financial institutions and real economy actors with the data-driven insights needed to make adaptation investment decisions. Separately, some insurers are exploring ways to link risk reduction benefits to premium credits or higher limits, through the use of KPI-linked structures, and by integrating resilience actions into client solutions. Some insurers are establishing partnerships with specialist service providers (e.g. wildfire defence) to offer risk-based discounts linked to service uptake.

Connecting insurer risk data to bank credit assessment: There is growing interest in deepening the linkage between insurers’ physical risk quantification capabilities and banks’ credit risk assessment processes. Insurers can perform portfolio-level physical risk assessments for corporates with large inventories of physical assets, providing granular data on exposure, expected loss, and the risk-reducing impact of adaptation measures - data that could inform credit analysis, pricing, covenants, and collateral management.41 Looking ahead, insurance availability is likely to serve as an early-warning indicator for critical climate risk situations, with direct implications for financial institutions - and strategic questions for supervisors.42

3.3 Financial market practices, instruments, and policies - banking and capital markets

Risk modelling and credit products: In the banking sector, the primary approach to supporting clients’ adaptation is developing adaptation-focused credit products and solutions, from sustainability-linked loans with resilience KPIs to different types of sectoral and SME resilience-related solutions and working capital products. Some banks note a shift towards the integration of resilience considerations into mainstream project financing processes. Banks are also supporting clients in their efforts to raise capital for adaptation and resilience investments in capital markets, including through structuring innovative use-of-proceeds instruments.43

Debate is evolving on whether methodological shifts in the treatment of physical climate risk and resilience in bank credit risk modelling may be warranted. Theoretically, if banks were to use physical exposure data to calculate climate hazard variables in probabilities of default (PDs) and losses given default (LGDs), there could be methodological options to integrate adaptation measures taken by borrowers;44 the ECB has reached a similar conclusion (see Box 4). The Cambridge Institute for Sustainability Leadership has also recently proposed a ‘resilience-adjusted’ approach to credit risk measurement integrating variables for physical climate risk exposure, insurance adequacy, and adaptation and resilience actions into adjustments to PDs and LGDs.45

Financial sector policy frameworks: Debate is evolving around the use of financial policy frameworks to specifically target adaptation investments - including, for example, the expansion of sustainable finance taxonomies to consider adaptation46 - and thereby make such investments more ‘visible’ for investors. However, there is no consistent evidence that policy frameworks such as taxonomies can materially influence the investability or cost of capital for taxonomy-aligned companies and projects.47 Further work is required to assess these interlinkages.

3.4 De-risking, blended finance, and public-private risk sharing

Public insurance mechanisms and fiscal capacity: The presence or absence of public fiscal capacity can impact the degree to which risks are priced in financial markets, on the basis of governments acting as the ‘ultimate holder’ of catastrophic risks. Insurance markets are a key channel to quantify risk exposure and make the value of adaptation investment visible to markets - and in many jurisdictions, markets rely on the presence of a public backstop for catastrophic risks. However, if not priced at a level that reflects underlying risk exposure, the availability of insurance could weaken the incentive to invest in adaptation measures,58 prolonging current risk configurations. This issue can be compounded by assumptions that the pricing and availability of insurance cover will not vary significantly over the life of an asset.

Government backstopping or layering of catastrophic risks can help address availability and affordability of insurance in certain regions and for specific physical risk perils. However, an expectation that governments will use fiscal resources to support individuals and businesses can dilute risk signals and reduce incentives to invest in adaptation measures. Furthermore, as the frequency and severity of physical climate impacts shift in response to climate change, public fiscal capacity to support post-disaster recovery is likely to come increasingly under strain.

Blended finance for adaptation: Blended finance - the use of concessional or public funding to improve the risk/return profile of investments for private capital providers - represents an important tool for financing adaptation activities that would not otherwise attract private investment at scale. Concessional instruments include first-loss capital, guarantees, interest rate subsidies, and technical assistance facilities. In 2024, global blended finance transactions totalled US$18.3 billion,59 though adaptation-focused deployments remain a small share and fall far short of estimated financing needs. By structuring layers of public and private sources of capital in alignment with risk/return expectations, blended finance structures can help address challenges associated with the lack of clearly defined revenue streams from adaptation investments, particularly those which are more ‘public good’ in nature.60 A range of blended finance structures are being deployed to mobilise private capital for adaptation investments, illustrating different approaches to bridging the gap between economic and financial value (see Box 5). Scaling these mechanisms requires both increased public funding and progress on the measurement and market architecture necessary to attract private capital on improved terms.

4. Looking ahead: priorities for action and conclusions on the role of private finance

More systematic valuation of avoided losses could have a broad array of benefits for both private actors and broader civil society. However, such a shift is one of a suite of broader transformative changes that may be necessary to turn adaptation investment needs into financeable opportunities. Looking ahead, a number of priorities emerge for further collaborative work and development.

4.2 Conclusions: understanding the role of private financial institutions in supporting adaptation and resilience

This paper has described the challenges associated with valuing avoided loss, and the implications of the related structural barriers that affect incentives to invest in adaptation and resilience. It has also explored innovations across the financial system that could help address these issues. On the basis of this analysis, it is evident that private financial institutions can approach adaptation and resilience priorities through both direct and indirect channels. Understanding this distinction is important for setting realistic expectations and identifying where focused action can have the greatest impact.

Through their core business activities, financial institutions influence adaptation outcomes in several important ways. Insurers are expanding advisory services for clients to help strengthen understanding of the return on risk reduction and implement adaptation and resilience solutions, and are working to share risk data and insights to inform market development; claims processes are also used as an intervention point to drive adaptation during recovery, often paired with advisory on resilient reconstruction. Banks are developing sustainability-linked loans with adaptation KPIs, serving as underwriters for adaptation-focused bonds, and structuring sector-specific resilience credit facilities, to help monetise the value of risk reduction. In investment and portfolio management, asset managers are increasingly incorporating physical risk and adaptation considerations into portfolio construction and stewardship activities. In risk pricing and assessment, financial institutions with more sophisticated physical risk modelling capabilities are progressively linking these to credit and investment decision-making, helping to make the financial value of adaptation more visible. Beyond direct product design, pricing, and service relationships, financial institutions could be more active in supporting adaptation measures through:

These indirect contributions could play a significant part in shaping the pace of risk reduction and adaptation investment across the real economy.

At the same time, it is important to be clear about the constraints on financial sector action. Financial institutions cannot independently scale adaptation-linked activity in the absence of appropriate enabling conditions and risk environments. Insurance pricing and underwriting decisions play a critical role in signalling risk and incentivising risk reduction, but they do not, on their own, generate sustained adaptation investment without supportive public policy, risk mitigation measures, and data availability. Financial institutions also face the risk of countervailing outcomes: rational risk management responses to increasing physical climate risk - such as adjusting insurance pricing, tightening lending terms, or reallocating capital away from exposed geographies - can reduce the adaptive capacity of the very clients and communities most at risk. This raises a challenging policy conundrum at the intersection of three interlinked imperatives: the need to ensure that markets price risk efficiently; the need to ensure that households, corporates, and governments can access finance to invest in adaptation; and the need for financial institutions to manage risks while enabling economic growth.

Scaling up adaptation finance therefore requires concerted action across policymakers, regulators, corporates, financial institutions, and market infrastructure providers. The priorities for action outlined above reflect this shared responsibility. The key challenge is not classifying what counts as adaptation - but clarifying who pays, who benefits, who bears residual risk, what is contractible, what is insurable, and what sits on the public balance sheet. Where enabling conditions are in place, financial institutions are well positioned to mobilise capital, structure appropriate products, and support adaptation at scale.

Annex 2: Instruments for monetising avoided losses and financing adaptation

Developing practical mechanisms to monetise the economic value of avoided losses is a foundational challenge for adaptation finance. This annex describes the emerging market mechanisms and instruments being explored to address this gap. It also provides a catalogue of adaptation financing instruments currently in use across sectors and geographies.

Annex 2.1: Emerging instruments

Tradeable resilience credits. A 2024 paper from Duke University’s Nicholas Institute proposes a system of tradeable ‘resilience credits’ as a new asset class to translate avoided climate losses into a standardised instrument.67 Under this model, the primary beneficiary of an adaptation investment (e.g. a municipality investing in flood infrastructure) would generate resilience credits representing verified avoided losses - which could then be sold to indirect beneficiaries such as multinationals with exposed supply chains or institutional investors seeking to offset portfolio-level physical risk exposures. The mechanism draws structural parallels with carbon credit markets, applying similar approaches to measurement, reporting, and verification to a physical risk context. However, it faces a fundamental valuation barrier linked to the challenges described in the main text: the absence of a universal unit of resilience value, the localised nature of benefits, the difficulty of attributing avoided losses to specific measures, and the lack of robust measurement and verification methodologies at scale.

Climate Damage Index derivatives. A 2024 paper by Ilinski, Bouev and Lobanov proposes creating a derivatives market for swaps on parametric Climate Damage Indices (CDIs) representing modelled insured expected losses by region from climate events.68 Under this structure, a portion of swap premiums would flow into state-run adaptation funds, creating a financial nexus between the pricing of climate risk in capital markets and public investment in resilience. The CDI approach leverages existing insured loss modelling capabilities and could in principle operate without requiring a universal unit of avoided loss. Significant development work would be needed to establish credible CDI methodologies, standardise contract terms, and establish market infrastructure.

Both mechanisms are at early stages of development and face significant valuation and market infrastructure barriers. Progress would require standardised avoided loss measurement frameworks, coordination between public and private actors, and regulatory clarity on the treatment of adaptation-linked instruments. Notwithstanding these challenges, they represent potentially important pathways for bringing private capital into adaptation at scale.

Annex 2.2: Catalogue of adaptation financing instruments

The tables below provide an illustrative catalogue of adaptation financing instruments currently in use or in development, spanning credit, insurance, equity, and blended finance structures across key sectors. For each instrument type, the tables set out illustrative real-world examples and the types of KPIs and metrics used to link financing terms to adaptation outcomes.

Credit and debt instruments

SectorInstrument / modelIllustrative examplesKPI / metric typesEconomic value / cash flow linkage
Built environmentClimate resilience bonds / green bonds with resilience use-of-proceeds for flood protection, drainage, resilient urban services, and climate-proofed buildings.EBRD Climate Resilience Bond (US$700 million, 2019); municipal and utility green bonds financing drainage, flood protection and resilient urban services.Physical risk assessment completed; asset compliance with resilience design standards; beneficiaries / assets protected; avoided damage estimates; reduced outage or downtime days; service continuity metrics.Economic value comes from lower expected loss, lower repair capex, more stable revenues, better debt service coverage, and sometimes broader investor demand and pricing support from labelled-bond buyers.
Built environmentSustainability-linked loans / bonds with adaptation KPIs for property and infrastructure operators.Emerging structures highlighted in adaptation KPI guidance for infrastructure and resilience-linked finance.Share of portfolio / assets meeting climate-resilient standards; implementation of adaptation capex plans; reduction in interruption time; resilience governance milestones.Margin step-downs or step-ups translate KPI achievement into lower or higher financing cost; lenders can also justify stronger credit appetite if resilience lowers physical risk exposure.
