Marsh released its 2026 Climate Adaptation Survey, finding that 43% of surveyed organizations suffered losses or disruptions from extreme weather between 2023 and 2026. The findings underscore a rising trend in corporate risk management as entities grapple with increasingly frequent climate-related perils.
Why it matters
As 62% of respondents anticipate that insurance availability or costs will worsen over the next five years, businesses are under mounting pressure to formalize their adaptation strategies. The report highlights how organizations are shifting their focus to mitigate the financial impact of weather-driven interruptions.
Flooding emerged as the leading climate peril for 62% of respondents, followed by heat stress at 36%. Meanwhile, 60% of organizations reported impacts from multiple distinct weather perils.

Respondents anticipate insurance costs and availability will worsen between 2026 and 2031.
Seasonal Patterns
This report follows the framework established by the Marsh Climate Adaptation Survey to quantify how global organizations are adjusting their risk models to account for more frequent extreme weather events. The data marks a departure from historical reactive measures as companies increasingly treat climate hazards as a multi-peril, permanent operational risk.
The report suggests that businesses prioritize investments in asset engineering and robust business continuity plans to mitigate potential disruptions. Leaders should anticipate rising insurance premiums and evaluate their current multi-peril assessment methods to improve future negotiation power.
The takeaway
Proactive adaptation measures like asset engineering may help businesses secure better terms in future insurance negotiations. Organizations that ignore the threat of multi-peril climate events face higher operational uncertainty and increased long-term insurance costs.
