How Boards Are Underestimating Climate Risk — and What To Do About It

Introduction
Financial institutions, corporate executives and investors are operating with climate risk models that systematically underestimate exposure by a factor of two to four times, according to a recent FTI Consulting report. This represents one of the most significant mispricing phenomena in modern capital markets, materializing today across credit spreads, equity valuations and capital allocation decisions.
FTI Consulting analyzed 148 global companies representing $31.4 trillion in market capitalization to test whether current climate risk models provide decision-useful intelligence. The findings are stark: conventional platforms project approximately 2% portfolio losses, while our integrated analysis reveals 7.7% average exposure — a nearly four-fold gap that stems from a combination of systematically underweighting transition risks relative to physical climate impacts and insufficient specificity and resolution of top-down sectoral models.
What Boards Need to Recognize
In our view, given the potentially significant underestimation in current climate risk methodologies, how financial markets, business leaders and policymakers respond to this measurement gap will influence competitive dynamics through 2030. Organizations that are proactive even in a delayed recognition context will benefit from establishing early leadership via building resilience and adaptation capabilities, which will become a core competitive advantage when the regulatory context starts to gain momentum.
Our research generates several unambiguous imperatives for boards — as well as senior business leaders, investors, financial services executives and policymakers navigating the intersection of climate risk, transition planning and capital allocation.
First, recognize that current climate risk models are not conservative; they are inaccurate. The nearly four-fold gap between 2% conventional estimates and our 7.7% integrated assessment is not a matter of risk appetite or analytical preference. It reflects systematic measurement error. Boards must understand that they are operating with materially incomplete information about business performance and portfolio exposure — information that directly affects their ability to assess transition plan viability, price transition finance appropriately and distinguish credible decarbonization strategies from greenwashing.
Second, acknowledge that the time horizon for climate impact is shorter than assumed. Our 15-year analytical window, directly relevant to typical loan tenors, investment holding periods, long-term business strategy and planning, and even macro-policy design, already captures material exposure.
Institutions treating climate risk as a 2050 or 2080 phenomenon are fundamentally misreading the risk timeline. The exposure is near-term, and the mispricing is occurring now. This temporal reality has profound implications for transition planning; companies require transition strategies delivering measurable progress within five to 10 years, not aspirational 2050 targets. Boards must evaluate transition plans against this compressed timeline, assessing whether proposed pathways generate sufficient risk reduction and competitive positioning within decision-relevant horizons.
Third, note that transition risk exceeds physical risk in both magnitude and urgency. Our findings consistently demonstrate that policy changes, technology disruption and market shifts driven by decarbonization create larger and more volatile financial impacts than direct physical climate effects. Yet most institutional frameworks focus predominantly on physical risk. This imbalance must be corrected, particularly for transition finance assessment.
Evaluating a company’s transition plan requires quantifying exposure to carbon pricing, stranded asset dynamics, technology disruption, regulatory changes and competitive repositioning. Boards focusing primarily on physical adaptation while underweighting transition dynamics cannot effectively evaluate the very strategies transition finance seeks to enable.
Governance Implications of Climate Risk
Directors and trustees face specific governance implications from underestimating systematic climate risk. These include:
- Fiduciary Duty Exposure: Operating with materially incomplete risk information, particularly when the underestimation is quantifiable and the solution is available, creates potential liability. If a nearly 4x measurement error affects portfolio valuations, lending decisions and capital allocation, directors may not be able to credibly claim appropriate oversight without demanding analytical upgrades.
- Strategic Risk: Competitors with accurate climate risk models are gaining measurable advantages in three areas: (1) superior risk-adjusted returns through precise credit pricing; (2) market share in high-growth transition finance segments; and (3) preferred relationships with climate-conscious corporates seeking sophisticated capital partners. These advantages compound, and with each quarter your institution operates with inferior analytics and insights the competitive gap may widen.
- Regulatory Risk: Climate stress testing has moved from disclosure exercise to supervisory expectation. The European Central Bank’s 2022 climate stress test identified approximately €70 billion in combined losses under disorderly scenarios in its limited scope exercise. Supervisors are comparing institutional approaches. Those organizations demonstrating systematic underestimations face heightened capital requirements, additional reporting obligations and potential enforcement.
- Reputational Risk: Transition finance deployed based on inadequate risk assessment creates dual exposure. First, capital may concentrate in companies with aspirational instead of executable transition plans, generating poor risk-adjusted returns when plans fail to deliver. Second, media and stakeholders increasingly scrutinize whether transition finance genuinely supports decarbonization or constitutes greenwashing. Superior analytics help distinguish credible strategies from window dressing.
What Boards Can Do
Climate risk quantification must escalate from a risk function technical project to board-level strategic priority to drive operational, financial and strategic advantage. Across jurisdictions, emerging principles governing board actions include:
- Duty of Care: Directors must inform themselves about material climate risks affecting the business and enhance their understanding and capability related to climate risk management.
- Duty of Loyalty: Directors must act in the corporation’s best interests, which increasingly includes long-term climate resilience.
- Risk Oversight: Climate risk should be integrated into enterprise risk management.
- Scenario Planning: Many regulators expect boards to consider increasingly mature and comprehensive climate scenario analysis in line with International Financial Reporting Standard S2 or equivalent requirements.
- Strategic Integration: Climate considerations should inform business strategy, not just compliance.
Remember that although the problem at hand may be complex, there’s significant upside to tackling it effectively. Boards at companies that master company-specific climate risk quantification can see great success in capturing competitive advantages through superior risk-adjusted returns, effective transition finance allocation and enhanced stakeholder credibility.
