Executive summary

Climate adaptation is evolving from a risk-measurement exercise into a significant structural investment opportunity. As physical climate impacts intensify, demand is growing for products, services, and infrastructure capable of strengthening system resilience. External projections suggest that annual demand for adaptation and resilience could reach US$0.5–1.3 trillion by 2030, with private-capital opportunities in resilience technologies estimated at approximately US$1 trillion. The report evaluates 102 adaptation activities, finding that 95 per cent have modelled benefits exceeding costs, with a median benefit-cost ratio (BCR) of 3.1x. However, the current relationship between social value and investment returns is weak, indicating that policy incentives must change to unlock private capital at scale.

Context and scene setting

Global physical climate risk has become a material macroeconomic threat. Financial consequences are felt through property destruction, lower labour productivity, and disrupted supply chains. In 2025, total economic losses from natural catastrophes reached US$220 billion, while the global protection gap rose to US$424 billion. In the United States, the frequency of billion-dollar disasters has increased from an average of 3.3 per year in the 1980s to 23 annually between 2020 and 2024. Forward-looking scenarios suggest that even under optimistic net-zero pathways, risks could reduce global GDP by 7 per cent by 2050. Adaptation is defined as specific interventions (such as flood barriers), while resilience refers to the broader capacity of an organisation or system to withstand and recover from shocks.

Policy momentum is increasing, with the UAE Framework for Global Climate Resilience adopted at COP28 and the subsequent 59 Belem Adaptation Indicators established at COP30. National Adaptation Plans (NAPs) have become central mechanisms for identifying climate vulnerabilities; 172 out of 197 countries now have at least one national policy in place. Despite this, private capital currently contributes less than 10 per cent of tracked climate adaptation finance. The report notes that the financing need is much larger than current flows, with annual adaptation needs in developing countries estimated at US$310–365 billion by 2035.

Our adaptation framework

The research identifies 102 climate adaptation activities across physical infrastructure, products, services, and digital enablers. The framework utilises an avoided-loss metric, expressed as a BCR, to determine the present value of expected physical losses mitigated for every dollar spent. Results show that 93 per cent of activities clear the modelled economic threshold (BCR > 1.0x). The highest-ranking activities include evacuation planning and infrastructure (11.8x BCR), storm-resistant construction (10.9x), and early warning systems (10.3x). Conversely, digital enablers often score lower because their contribution to loss reduction is indirect and realised through broader system reliability.

The analysis also examines “dual-benefit” activities that provide both strong adaptation and meaningful mitigation co-benefits (avoiding more than 50 tCO2e per $1 million invested). One-third of the activities (27 out of 102) meet this criteria, including nature-based solutions like mangrove restoration and peatland restoration, as well as precision agriculture and AI-enabled climate risk modelling. The report highlights that the highest BCR activities are not necessarily those with the highest mitigation benefits, creating a unique opportunity for investors to prioritise activities that address both dimensions simultaneously.

Applying the framework to investment portfolios

Investability is determined by three components: expected internal rates of return (IRR), access via holdable instruments, and scale. Modelled sector IRRs vary significantly, with climate analytics and wildfire technology offering 16–23 per cent, while water infrastructure and flood protection typically range between 8–16 per cent. The report finds no documented evidence of a durable “adaptation alpha” in the finance literature, but suggests reframing adaptation as an underpriced “quality” attribute. Firms that harden their productive assets should experience lower earnings variability and thinner downside tails, potentially justifying a quality premium.

For listed-equity portfolios, the framework suggests using benchmark-relative tilts. A modest tracking error budget of 9 basis points can raise a portfolio’s avoided-loss score to 10x the benchmark. Private markets offer direct exposure to pure-play assets in infrastructure, real estate, and venture capital, though they carry illiquidity and execution risks. Additionally, insurance-linked securities and catastrophe bonds provide macro-uncorrelated returns and act as an effective source of diversification. Active ownership is recommended as a fifth channel, with the report outlining a sequence for engaging with companies to disclose material physical climate impacts and implement resilience plans.

Appendix

The appendix maps the 102-activity framework against existing taxonomies, showing that it provides 75 per cent total coverage of the EU Taxonomy and GCA Adaptation Finance Framework. It exceeds most frameworks in its coverage of digital and information services. A detailed list of suggested actions for corporate engagement is provided, covering workers and local communities, operational resilience, governance, and supply chain resilience. Key questions for investors include assessing the adequacy of insurance coverage and the integration of physical climate risks into enterprise risk management frameworks.
