Marsh playbook warns insurability hinges on place-based climate resilience amid $145 billion 2025 insured catastrophe losses

Marsh & McLennan published a climate resilience playbook with the World Economic Forum focused on place-based risk management to support insurability.

• Global insured natural catastrophe losses totaled $145 billion in 2025, raising macroeconomic and political risks via higher household exposure.
• Insurance availability increasingly depends on resilience of entire locations, shifting focus from individual assets to shared protective systems.
• The framework targets coalition action on risk data, pooled financing, standardized resilience metrics, incentive alignment to scale investment.
