Climate adaptation 2026 report

Marsh’s Climate Adaptation Survey helps businesses prepare for the changes and challenges ahead.

Climate risk is becoming more complex, more systemic, and more immediate. Effective adaptation now goes beyond protecting physical assets, operations, and people — it also depends on the suppliers, infrastructure, and wider systems organisations rely on.

Now in its third year, Marsh Risk’s 2026 Climate Adaptation Survey captures the views of more than 120 organisations across eight regions. It looks beyond physical assets to examine the wider network of operations, people, suppliers, infrastructure, and communities they rely on — revealing where resilience is strengthening, where vulnerabilities still persist, and where the greatest opportunities for action lie.

The survey shows that, despite facing multiple climate-related hazards, many organisations are not conducting forward-looking assessments. And among those that do, many are not acting on the results. For example, 60% of respondents are grappling with multi-perils, such as flood, extreme heat and water stress, yet only just over half of the respondents are conducting an assessment.

Taken together, the survey results offer a benchmark to help organisations prioritise action and shape their climate adaptation strategies. They also highlight both encouraging progress and persistent gaps in preparedness as businesses respond to a changing physical risk landscape.

Findings in detail for business leaders and risk managers

From heat to water stress, organisations are responding to a changing physical risk landscape

Respondents are grappling with multiple hazards (60%) with flooding, extreme heat and water stress emerging as the top three risks — and in regions like Asia, all three are occurring simultaneously.
The case for forward-looking assessment has never been clearer, yet only just over half (57%) are actually doing it.

Those doing forward-looking assessments are doing it better, and looking well beyond asset damage

Of those who are conducting forward-looking assessments, the methodology has become more sophisticated: the share (77%) using quantitative methods has increased from last year (52%).
Physical assets remain the primary focus of assessment (91%), but respondents are widening the lens — increasingly assessing risks to critical infrastructure (62%) and suppliers (54%) as climate damage extends far beyond property damage.

Forward-thinking respondents are starting to invest in system resilience as part of their adaptation strategy

Despite fewer than half of respondents conducting forward-looking assessments, the majority (78%) are considering or developing adaptation strategies — with a quarter of respondents (26%) having a formal plan in place.
The shift is also telling: respondents are moving beyond asset-level resilience (40%) toward system-level adaptation, including business continuity planning (54%), collaborating with local government on place-based resilience (35%), strengthening supply chains (35%), and partnering with critical infrastructure providers (28%).
This signals a clear message: climate impacts are rippling through operations, supply chains, and the wider systems businesses rely on. It also echoes our property engineering findings, where emergency response emerged as the key opportunity identified through site surveys.

Insurability concerns are rising but translating adaptation into insurance outcomes still has a long way to go

A quarter of respondents (24%) are concerned about insurance availability at their next renewal and concern rises (62%) significantly over a five-year horizon. Respondents can capitalise on the benign market to strengthen their resilience and prepare for future hardening.
Yet only 26% say adaptation measures are being recognised in insurance negotiations, showing that while documented risk reduction can help, translating adaptation into tangible insurance benefit still has a long way to go.

From operational concern to boardroom priority — risk management is the primary adaptation driver

Risk management remains the dominant driver for action (40%), elevating the need for climate adaptation from an operational concern to a strategic one.
Beyond risk management, external drivers include government and regulatory (31%) and investor pressure (25%), all shaping organisational priorities.
