Climate-related risks change how investors, insurers, and communities value assets whose economic life spans decades. Physical risks from rising seas, floods, wildfires and heatwaves alter expected cash flows and replacement costs, while transition risks from policy, technology, and market shifts can render infrastructure or reserves obsolete. Evidence on these channels has been emphasized by Mark Carney of the Bank of England, who warned of a potential "dramatic reassessment" of asset values if risks are mispriced, and by Nicholas Stern of the London School of Economics, whose work highlights long-term economic damages that feed into valuation models.
Types of climate-related risks
The Intergovernmental Panel on Climate Change reports that increases in extreme events and sea-level rise are likely to intensify local hazards and economic losses, especially in exposed coastal and arid regions. The Task Force on Climate-related Financial Disclosures chaired by Michael Bloomberg and Mark Carney recommends that firms disclose exposures to both physical and transition risks and use scenario analysis to capture uncertain but material outcomes. These categories matter because they act through different valuation mechanisms: physical risks depress future revenues and raise maintenance or relocation costs, while transition risks change the regulatory or market environment and can create stranded assets.
Mechanisms and consequences for valuation
Valuation impacts occur through altered expected cash flows, higher required returns, and shifts in comparables. When insurers raise premiums or withdraw coverage in high-risk territories, the cost of capital for real assets rises and market liquidity can vanish, producing sharp local price declines. Changing consumer preferences or carbon pricing can abruptly reduce demand for fossil-fuel reserves or carbon-intensive industrial facilities, exemplifying how transition policy can accelerate depreciation. Local cultural attachments and territorial governance influence outcomes: communities with strong heritage ties may resist relocation, complicating cost estimates, while jurisdictions with proactive planning can preserve asset value by investing in resilience.
For long-lived public infrastructure and real estate, failure to integrate credible climate scenarios into discounting and stress testing risks systematic mispricing across portfolios. The policy implication emphasized by leading authorities is clear: prudent valuation requires transparent scenario analysis, forward-looking disclosure, and collaboration between planners, firms, and financiers to reflect both immediate exposures and long-term transformation. Ignoring these dynamics risks abrupt repricing with social and environmental consequences concentrated on the most vulnerable places and people.
