Study: 79% of Data-Center Capacity at High Climate Risk
A First Street study finds 79% of global data-center capacity sits in markets exposed to acute climate hazards such as floods, extreme winds and wildfires, signaling higher outage costs and resilience spending ahead. For CFOs, CIOs and investors, that means planning for bigger insurance bills, more cooling and redundancy capex, and revisiting site-selection across assets that typically operate 20–30 years.
Key Takeaways
- First Street finds 79% of global data-center capacity exposed to acute climate hazards across 97 markets.
- Just over half of data-center capacity is in markets facing chronic stress from extreme heat and drought.
- Asia‑Pacific shows the highest acute exposure at 89%; Americas 50%; Europe, Middle East & Africa 46%; Nordic markets lowest.
- System-level risks—grid access, water availability, egress and community vulnerability—mean traditional underwriting can underprice climate risk.
- Digital Realty operates roughly 300 centers using waterless or closed‑loop cooling as a mitigation example.

MarketMoodz Analysis
The study reframes data centers as long-lived infrastructure that will face rising operating costs as climate hazards intensify. Higher insurance premiums, more frequent repair bills and greater downtime risk will push operators and owners to budget for resilience capex—cooling upgrades, water-efficiency retrofits and power redundancy—that can compress near-term free cash flow and raise total cost of ownership. Market concentration matters: expansion into high-risk markets such as Northern Virginia, Johor and Marseille could materially increase portfolio-level exposure, while Nordic markets emerge as relatively safer options.
Risk models that rely on historical weather and precipitation records will miss future shifts in hazard frequency and severity; that matters because data centers typically run for 20–30 years. Underwriting and valuation that ignore forward-looking climate scenarios risk mispricing assets and misallocating capital. System-level factors—local grid reliability, water access, site egress and community socioeconomic vulnerability—amplify exposure and complicate simple location-based risk scores, so investors should evaluate both site- and system-level resilience when comparing markets.
What to watch next: review First Street’s full methodology and independent verification of its market rankings; monitor insurer pricing and policy availability for data-center risk; track capex plans from major operators and whether site-selection criteria shift away from high-risk expansion markets. Investors should press for transparent climate-adjusted stress testing, require disclosure of cooling and power redundancy, and build scenario-based outage cost estimates into underwriting and capital allocation.
