Key Takeaways
- 1.Physical climate risk is shifting into a recurring P&L operating cost rather than a distant tail risk, with mid-teens EBITDA at risk by 2050 in exposed sectors and an estimated $1.3T already being spent globally in 2026 on business continuity and adaptation capex.
- 2.Water security is becoming a major macroeconomic constraint across Europe, with 15% of euro-area GDP exposed to high water scarcity risk and a €23bn annual investment gap on top of current €55bn annual infrastructure spend.
- 3.Surging AI data center power demand and environmental constraints are converging, running directly into grid bottlenecks and power infrastructure capacity limits.
