In an era of relentless climate disruption, board directors face a new mandate: safeguard their companies against climate risks as part of their fiduciary duty. Gone are the days when wildfires, floods, and heatwaves could be dismissed as once-in-a-century events. Today, climate-related shocks are material business risks – disrupting supply chains, damaging assets, and upending financial forecasts. Shareholders and regulators now expect boards to ensure their organisations can adapt and thrive amid these impacts, not merely reduce emissions. In the explainer article “Climate Adaptation 101: Why It Matters More Than Ever,” we argued that climate adaptation is not optional, but a core strategic necessity. Failing to prepare for climate extremes is not just poor management – it may well be a breach of directors’ legal and ethical responsibilities in the age of climate disruption.
Adaptation as a Fiduciary Responsibility
Leading voices in finance and governance have made it clear: addressing climate risk falls squarely under fiduciary duty. Back in 2015, Bank of England Governor Mark Carney warned that ignoring climate change could “breach fiduciary obligations.” A decade later, that warning has become more direct – by 2025 experts were declaring that “climate risk is now fiduciary duty”. This shift reflects a global consensus that protecting long-term shareholder value requires proactive climate risk management. Climate change is no longer a distant CSR issue; it is a boardroom issue of strategic, financial, and legal significance.
Global frameworks and regulators are reinforcing this point. The World Economic Forum notes that investors and regulators are challenging companies to demonstrate a “strategic approach to addressing climate-change risks and opportunities,” and it emphasizes the board’s duty of long-term stewardship in navigating these risks. In practice, this means boards must actively govern climate adaptation just as they do other enterprise risks. The Task Force on Climate-Related Financial Disclosures (TCFD) – now a de facto global standard – explicitly calls for disclosing the board’s oversight of climate-related risks and opportunities. In fact, many countries (from the UK to Japan) have made TCFD-aligned reporting mandatory, underscoring that board oversight of climate risk isn’t just best practice; it’s becoming expected practice.
New sustainability reporting standards are raising the bar further. The International Sustainability Standards Board (ISSB) released climate disclosure rules in 2023 that require companies to conduct climate scenario analyses and report on the resilience of their business strategies. In other words, boards will need to assure investors that management has tested the company’s future against severe climate scenarios – and that the organization can weather the storms (literally and figuratively). Likewise, the EU’s Corporate Sustainability Due Diligence Directive, which came into force in 2024, now mandates large companies to adopt climate transition plans aligned with the Paris 1.5°C goal. Directors are obliged to integrate these plans into corporate strategy and take “corrective action” if the business model is not Paris-compatible. While this EU law focuses on mitigation, it sends a broader message: climate competency is being encoded into directors’ duties by law.
Critically, adaptation – strengthening the company’s resilience to physical climate impacts – is emerging as part of that duty. The UN Principles for Responsible Investment (UNPRI) have long argued that considering ESG issues (including climate risks) is a requirement of fiduciary duty, not a contradiction of it. The logical extension is that boards must ensure their companies are adapted for climate impacts to fulfill duties of due care and loyalty. Failure to do so can carry real consequences. In an unprecedented 2023 lawsuit, a shareholder coalition led by ClientEarth sued the Board of Shell for “failing to manage material and foreseeable climate risks,” arguing this breached the directors’ legal duties under UK company law. While the case was dismissed on procedural grounds, it signaled a new precedent: board directors can be held accountable for inadequate climate risk management. Whether through litigation, investor activism, or regulatory enforcement, the message is clear – ignoring climate adaptation is a governance red flag.
On the positive side, embracing climate resilience aligns with core fiduciary objectives of sustaining value and competitiveness. Companies that invest in adaptation see tangible benefits: more reliable operations, stabilised supply chains, and new avenues for innovation. In short, climate adaptation is prudent risk management and strategic foresight. Boards that lead on this issue aren’t just avoiding downside risk; they are positioning their firms for long-term success in a disrupted world. As one global business report put it, “to be competitive, a leading business must adapt.”
Red-Flag Questions Boards Should Be Asking
How can boards tell if their organisations are truly climate-resilient or if they’re flying blind into the storm? A powerful tool at the board’s disposal is inquiry – asking the right probing questions of management. The following red-flag questions can help directors uncover gaps in climate resilience strategy, scenario planning, governance, and resource allocation:
- “What climate change scenarios are we testing against, and what do they reveal?” – Has management conducted rigorous scenario analysis (e.g. a 2°C, 3°C, or worst-case scenario) to assess our business’s resilience? What did we learn about potential impacts on operations, supply chains, and markets – and are we planning for those outcomes?
- “Which assets and operations are most vulnerable to climate extremes?” – Where are our critical facilities located in relation to rising seas, wildfire zones, or extreme heat regions? Have we done climate risk assessments for all major sites and supply nodes? What is the adaptation plans for high-risk assets – for example, flood defenses, backup energy, or alternative supply routes?
- “Is climate risk integrated into our governance and strategy?” – Do we have clear management ownership of climate resilience (e.g. a chief risk officer or sustainability head accountable for adaptation initiatives)? How often does the board or a board committee review climate risk updates? Are climate considerations embedded in our enterprise risk management, investment decisions, and strategic planning, rather than treated as a siloed ESG issue?
- “What resources are we dedicating to climate adaptation?” – Do our budgets and capital plans include funding for resilience measures (e.g. infrastructure hardening, diversification of water sources, supply chain buffers)? Is the level of investment commensurate with our exposure to climate threats, or are we dangerously underinvesting in prevention?
- “How will we respond when (not if) a climate disaster strikes?” – Does the company have up-to-date business continuity and disaster recovery plans for events like prolonged power outages, major floods, or supply breakdowns? Have we learned from recent crises in our industry to improve these plans? Who are the external stakeholders (emergency services, community partners) that we’ll coordinate with during climate emergencies?
If management cannot answer these questions confidently and quantitatively, that should raise red flags for the board. As the WEF’s climate governance principles advise, directors should be prepared to challenge management on climate matters and insist that climate risks stay at the top of the agenda. In practice, this might mean pressing for a formal climate risk briefing at each board meeting or even creating a dedicated board climate committee to ensure sustained focus (as some leading companies have done). The goal is not to trip up management, but to surface blind spots and drive a culture of no-surprises when it comes to climate resilience. A board that asks tough questions now is far less likely to be blindsided later.
Metrics to Monitor Climate Resilience
In addition to asking questions, boards need hard metrics to monitor the company’s climate resilience over time. Just as we track financial KPIs, we must track resilience KPIs to know if adaptation efforts are effective. Here is a short set of practical metrics directors can use to gauge progress:
- Frequency of Climate-Related Disruptions: Track the number of climate-related events impacting the business each year – for example, how many times have floods, storms, heatwaves, or wildfires caused operational disruptions or damage? A rising trend signals growing exposure. Conversely, a reduction (or effective mitigation of impacts) over time would indicate improved resilience.
- Operational Downtime and Recovery: Measure business downtime or productivity loss due to extreme weather and the time to recover. Metrics can include production uptime (days in operation) vs. downtime due to climate events, or supply chain interruptions per year. Boards should see this number of lost days shrinking as adaptation measures are taken. Rapid recovery times are a key indicator of resilience.
- Adaptation Investment and ROI: Monitor the company’s investment in adaptation – e.g. capital expenditures on facility hardening, new water infrastructure, backup energy systems, climate analytics, etc. – as a percentage of overall capex or operating costs. Alongside this, track the avoided losses or cost avoidance attributable to these investments.
- Resilience Scorecard: Develop an internal resilience index or scorecard to rate the preparedness of key business units or sites. This could synthesize various factors (risk assessment completion, adaptation plan implementation, emergency readiness, etc.) into a composite score. Over time, the board can track this score to ensure it’s improving, similar to a credit rating for resilience. If an existing risk score framework exists, consider aligning it with a climate resilience scoring system for consistency.
Adaptation Leadership in Action: A Board-Level Case
What does effective board governance of climate adaptation look like in practice? One compelling example comes from the Philippines, a nation on the frontlines of climate impacts. Metro Pacific Investments Corporation (MPIC) – a major infrastructure conglomerate – recognised that in a country hit by ~20 typhoons a year, resilience must be embedded at the highest levels of decision-making. MPIC’s board took several bold steps to govern for climate resilience:
- They established a Board-level Sustainability Committee to oversee climate and ESG issues, ensuring that these considerations are integrated into core business strategy. This committee meets frequently (often more than once a month) and has the clout to pause or veto projects that don’t meet the company’s climate and sustainability criteria.
- The board deliberately brought in relevant expertise and education. The Sustainability Committee is chaired by an environmental economist, and the entire board undergoes mandatory training on governance of climate and sustainability issues. This empowered directors to “ask the right questions” and challenge management on climate matters from an informed standpoint.
- Crucially, MPIC’s board backed its oversight with action. In one case, when management proposed a new toll bridge that would cut through a sensitive mangrove forest, the board flagged it as misaligned with the company’s climate commitments. They required management to redesign the project, incurring additional cost and time, in order to reroute the bridge and protect the mangroves. This decision was made to uphold long-term resilience and avoid environmental harm, even if it meant short-term trade-offs. The result was a project aligned with climate adaptation principles – safeguarding natural coastal buffers (mangroves) that protect against storm surges, while preserving the company’s reputation and license to operate.
The MPIC case illustrates how proactive board governance can drive real adaptation outcomes. By embedding climate risk into oversight structures, building climate competency at the board level, and insisting on resilience criteria for projects, the board ensured the company not only avoided climate-related pitfalls but actually strengthened its competitive position. MPIC moved to integrated reporting of sustainability and financial performance, giving investors a clear view of how it creates long-term value in a climate-challenged context. In short, the board treated climate adaptation as an opportunity for bold leadership rather than a mere compliance exercise – and the company is more robust for it.
Conclusion: Foresight, Duty, and Competitive Advantage
Climate change is often discussed in grim tones, but the narrative for boardrooms need not be doom and gloom. With strategic foresight and decisive governance, directors can turn climate disruption into an opportunity to future-proof their companies. Exercising oversight of climate adaptation aligns perfectly with fiduciary duty: it’s about protecting assets, ensuring long-term performance, and managing foreseeable risks. It’s also about upholding the societal license to operate – demonstrating to customers, employees, and communities that the company is responsibly navigating the challenges of a warming world. As the UNEP Adaptation Gap reports and IPCC assessments remind us, every year of delay in building resilience carries a cost, whether in financial losses or human well-being. The flipside is that early movers in adaptation often gain a competitive edge, by avoiding disruptions and earning trust as climate-resilient enterprises.
For board directors and non-executives, the call to action is clear. Governing for climate resilience is now part of good corporate governance, period. It requires the same rigor and urgency as financial auditing or strategic planning. Those who rise to the challenge will help steer their organisations through the age of climate disruption with confidence – fulfilling their duty to shareholders and stakeholders alike. In the boardroom, climate adaptation is not a distant “green” topic; it is business continuity, risk management, and value creation wrapped into one. By asking tough questions, tracking the right metrics, and insisting on resilient strategies, boards can ensure their companies are not only prepared for the next storm but also positioned to thrive in the climate of tomorrow.
