New research published by Marsh reveals that, while there is widespread acknowledgment of climate risks, organizations are not conducting comprehensive cost-benefit analyses to justify further adaptation investments. This is resulting in significant gaps between the outcome of climate risk assessments and adaptation strategies.
Marsh’s 2025 Climate Adaptation Survey analyses the responses of over 130 risk managers globally and reveals critical insights into how private sector organizations are responding to evolving climate risks. According to the research, 78% of organizations face climate-related impacts such as flooding, heat, and water stress, with 74% reporting asset losses and disruption stemming from these events. Yet only 38% perform detailed climate risk assessments, and 22% do not assess future climate impacts at all.
A significant portion of respondents (40%) to Marsh’s survey felt their organization lacks sufficient funding for effective climate adaptation, citing challenges such as the tendency for other business priorities to overshadow climate initiatives, a lack of knowledge and understanding about future climate scenarios, and competing interests for limited resources.
Amy Barnes, Head of Climate and Sustainability Strategy and Global Head of Energy & Power at Marsh, said: “Our research shows organizations consistently underinvest in climate adaptation relative to the severity of their identified risks. There is clearly an urgent need for organizations to adopt a holistic approach to climate risk, integrating asset-level and system-level assessments, and embedding climate adaptation into enterprise risk management frameworks. As climate hazards continue to intensify, proactive resilience planning is essential to safeguard assets, maintain revenue streams, and protect long-term business viability.”
