The ten highest-risk markets include Northern Virginia, the Carolinas, Atlanta, Johor, Singapore, Batam, Marseille, Bangkok, Beijing, and New York/Northern Jersey. Lowest-risk markets cluster in northern Europe (Stockholm, London, Copenhagen, Amsterdam, Oslo, Dublin) plus Toronto, San Francisco, Montreal/Quebec & Bogota. The industry is concentrating capacity in demanding locations rather than favorable ones. 30–50 percent of 2026 projects face delay as established hubs hit power, land & permitting constraints.
The central argument: climate risk is underpriced. Markets with comparable power costs and demand are underwritten as equivalent despite materially different risk profiles, affecting net operating income stability, insurance availability, debt capacity, and exit valuations. Climate risk must move from secondary consideration to core underwriting input, requiring adjusted operating assumptions, downtime and insurance stress-testing, and differentiation by long-term infrastructure reliability.
A climate risk report by First Street finds that 54 percent of global data center capacity operates under heat or drought stress, with 79 percent exposed to elevated flood, wind, or wildfire risk. Despite massive capital flows ($61 billion in 2025 alone) and projections of $6.7 trillion investment through 2030, physical climate risk is systematically overlooked in site selection and asset valuation.
The 18th First Street Risk Assessment evaluated 97 investible data center markets across chronic stressors (extreme heat, water scarcity) and acute hazards (flooding, wind, wildfire). Regional exposure varies sharply: Asia-Pacific faces the highest chronic stress (89 percent of capacity), while the Americas show greatest acute hazard exposure (86 percent). EMEA remains lowest-risk at 46 percent chronic and 25 percent acute.
Chronic stressors erode margins gradually through reduced cooling efficiency and higher energy consumption. Water scarcity constrains cooling capacity and raises operating costs, compressing net operating income and shortening asset life. Acute hazards create episodic disruption—physical damage, extended downtime, emergency capex, and insurance volatility. July 2022 UK cooling failures at Google and Oracle data centers exceeded design thresholds by 1.5°C; 2025 Texas flooding forced extended diesel generation and delayed maintenance. Redundancy systems may not offset disruptions when multiple inputs are constrained simultaneously during regional events.
Water operates across both risk categories. As chronic stress, drought constrains cooling systems. As acute hazard, flooding threatens power substations. US data centers consumed 17 billion gallons in 2023, with projections reaching 16–33 billion annually by 2028 for hyperscale facilities alone. High-risk markets (Asia-Pacific, southeastern US, Southern Europe) already face basin-level water constraints independent of data center demand.
