Extreme weather resilience: why it matters and how we’re building it

This paper examines why extreme weather resilience is becoming a core priority for infrastructure investors and how it should be built into investment decisions. It argues that infrastructure is both a major long-term investment opportunity and one of the sectors most exposed to physical climate risks such as storms, floods, heat, and wildfires. Because infrastructure assets are essential, long-lived, and often located in vulnerable areas, the paper positions resilience not as a sustainability add-on but as a financial discipline. It highlights the need to assess climate risks at the asset level, understand their potential commercial consequences, and invest early in targeted adaptation measures that protect operations, communities, and long-term asset value.

The paper’s findings show that the cost of inaction is far greater than the cost of adaptation. Extreme weather can damage assets, disrupt services, raise insurance costs, reduce revenues, and even create legal liability, as illustrated by the case of Pacific Gas & Electric in California. It also points to evidence that climate risk could significantly reduce infrastructure portfolio values and corporate earnings if resilience measures are not adopted. At the same time, the report finds that adaptation can generate strong returns: studies cited suggest that every dollar invested in resilience can produce substantial financial benefits through avoided losses, stronger economic performance, and wider social and environmental gains. Overall, the paper concludes that embedding resilience into infrastructure investment can both protect value and create it.
