Recent extreme weather events have demonstrated that climate change is no longer an abstract threat; it is an immediate and pressing reality that affects communities and businesses across all sectors.

As a Risk Professional, my view is that climate risk is no longer just a “popular narrative” tied to corporate social responsibility or a purely environmental concern; it is a strategic imperative that must be embedded into Enterprise Risk Management (ERM) frameworks. Today, it has become a topic directly linked to corporate operations and must be treated as a strategic priority. Climate-related risks now represent multidimensional threats—financial, operational, legal, and reputational—that shape a company’s competitiveness.

According to the IPCC Sixth Assessment Report, global temperatures are likely to exceed 1.5°C by the early 2040s, intensifying physical and transition risks for businesses worldwide.

Integrating climate risk into a company’s routine processes is inevitable. This integration can only be achieved by embedding climate risk into Enterprise Risk Management (ERM) frameworks. Such an approach is not only essential for regulatory compliance but also for long-term value creation, stakeholder confidence, and organizational resilience.

This article explores the key stages of addressing climate risks within an ERM framework and the strategic benefits of adopting a structured roadmap.

What Is Climate Risk?

Climate risk refers to the potential adverse impacts, direct or indirect, that climate change can have on a company’s assets, operations, supply chain, financial performance, and reputation. These risks manifest both as short-term disruptive events and long-term structural changes, fundamentally influencing strategic planning and sustainability goals. In literature, climate risks are typically categorized into three main groups:

Physical Risks: Direct Environmental Impacts

Physical risks stem from the direct environmental impacts of climate change:

• Acute risks: Sudden and severe events (e.g., floods, storms, wildfires).
• Chronic risks: Long-term changes (e.g., rising temperatures, sea-level rise, drought).

Impacts on companies:

• Damage to facilities and infrastructure
• Production disruptions and business continuity challenges
• Increased insurance costs
• Supply chain breakdowns
• Energy and water shortages
• Health and safety risks for employees

In 2022 alone, the U.S. experienced 18 climate disasters exceeding $1 billion each, totaling $165 billion in damages.

Transition Risks: Regulatory and Market Dynamics

Transition risks arise during the shift to a low-carbon economy and the growing expectations for sustainability. These risks are driven not only by regulatory changes but also by market dynamics, investor behavior, and technological transformation.

Key drivers:

• Policy and regulation: Carbon taxes, emission caps, cross-border carbon measures
• Technological change: Pressure to adopt new technologies
• Market dynamics: Shifts in consumer preferences toward sustainable products
• Investor pressure: ESG compliance expectations
• Reputational risk: Brand damage due to lack of sustainability

Impacts on companies:

• Existing business models becoming obsolete
• Increased investment and transformation costs
• Loss of competitive advantage
• Restricted access to capital

Investor pressure continues to accelerate climate-related disclosure efforts: following the transition from TCFD to ISSB Standards in 2023, companies are increasingly aligning with global sustainability reporting requirements, driven by regulatory mandates and investor expectations for transparency (IFRS Progress Report, 2024).

Liability Risks: Legal and Compliance Exposure

Liability risks include legal and financial consequences when companies fail to meet climate-related obligations:

• Inadequate or misleading climate risk disclosures (greenwashing)
• Litigation over climate-related damages
• Regulatory and investor demands for transparency
• Penalties for non-compliance with international standards

Understanding these risk categories is essential, as their combined impact extends far beyond environmental concerns and directly shapes a company’s financial stability, operational continuity, and strategic direction.

Here is a summary of the overall impact on companies.

• Financial: Declining asset values, rising operational costs, higher insurance premiums
• Strategic: Transition to new business models, divestment from high-risk sectors, supplier diversification
• Governance: Board-level accountability and mandatory reporting
• Competitive: Sustainability performance becoming a key differentiator
• Innovation: Need for new products and services
• Capital access: Lower financing costs for ESG-compliant firms

Challenges in Integrating Climate Risk into ERM

From my experience as an ERM Professional, risk assessment is the cornerstone of any ERM framework because it enables prioritization and informed decision-making. Yet, when it comes to climate risk, traditional qualitative approaches fall short of capturing uncertainty and long-term dynamics, making robust modelling indispensable. However, it is far more complex than conventional ERM risk calculations, with challenges spanning both technical and governance dimensions.

• Uncertainty and Long-Term Effects: Deep uncertainty makes probability-based models unreliable; scenario-based modelling is essential.
• Data Maturity and Accessibility: Climate data lacks consistency; historical records are incomplete.
• Complexity of Natural Systems: Nonlinear, feedback-driven climate systems challenge deterministic modelling.
• Geographic and Technical Data Limitations: Regional projections often lack resolution for site-specific analysis.
• Company-Level Parameters: Modelling requires granular data on asset vulnerability, operational dependencies, and adaptation capacity.
• Transition Risk Modelling Challenges: Policy uncertainty, technological adoption speed, market behavior, and financial impact are difficult to quantify.

Businesses that fail to adapt to climate risks could lose up to 7% of annual earnings by 2035, equivalent to the economic impact of COVID-19 every two years.

These challenges make ERM integration complex, and the inability to quantify financial impacts often leads decision-makers to deprioritize climate risk. However, delaying action is no longer an option. Companies must strengthen data infrastructure, adopt scenario-based modelling, and implement robust model risk management processes. Starting small is critical; building climate risk awareness into corporate culture ensures preparedness and resilience, turning proactive response into a standard practice.

Climate Risk Analysis in ERM: Hazard, Vulnerability, and Impact

In practice, I have seen that starting with hazard identification and linking it to actionable 4T strategies creates clarity for decision-makers and accelerates buy-in from senior leadership. This process involves three key stages: Hazard Identification, Vulnerability Assessment, and Impact Analysis, supported by the ERM principle of the 4T approach—Treat, Transfer, Terminate, Tolerate.

1. Hazard Identification

Identify potential climate-related hazards that could disrupt operations, such as: heatwaves, storms, floods, droughts, sea-level rise, or wildfires.

Example1: An energy company finds flood frequency increasing near a critical plant.
Actions (4T):

• Treat: Install drainage systems and flood barriers
• Transfer: Expand insurance coverage
• Terminate: Cancel expansion plans in high-risk zones
• Tolerate: Prepare emergency response plans

Example2: A logistics firm projects severe sea-level rise at a major port within 20 years.
Actions (4T):

• Treat: Elevate platforms and reinforce barriers
• Transfer: Secure long-term insurance
• Terminate: Halt capacity expansion at the port
• Tolerate: Develop short-term contingency plans

2. Vulnerability Assessment

Analyze which assets and processes are most exposed, such as: workforce, infrastructure, supply chain, IT systems, or brand reputation.

Example1: A factory’s drainage system is inadequate, risking 15-day production stoppage during floods.
Actions (4T):

• Treat: Upgrade infrastructure, diversify suppliers
• Transfer: Include disruption clauses in contracts
• Terminate: Redesign products to reduce dependency on single-source materials
• Tolerate: Monitor low-impact vulnerabilities

Example2: A food company sources 80% of raw materials from drought-prone regions.
Actions (4T):

• Treat: Build alternative supplier networks
• Transfer: Share risk through contractual terms
• Terminate: Reformulate products to reduce dependency
• Tolerate: Implement early warning systems

3. Impact Analysis

Evaluate potential consequences if risks materialize, such as: financial losses, operational downtime, reputational damage, or legal exposure.

Example1: Flood scenario analysis shows $500,000 daily revenue loss and $2M penalty risk.
Actions (4T):

• Treat: Develop business continuity plans
• Transfer: Purchase business interruption insurance
• Terminate: Avoid capacity expansion in high-risk areas
• Tolerate: Allocate financial reserves

Example2: Carbon tax projections indicate a 15% cost increase for an automotive manufacturer.
Actions (4T):

• Treat: Invest in energy efficiency and low-carbon technologies
• Transfer: Adjust long-term supplier contracts
• Terminate: Exit high-carbon product lines
• Tolerate: Manage short-term cost impact through pricing strategies

Conclusion

As a Risk Director, I believe that embedding climate risk awareness into corporate culture is not just good governance, it is a survival strategy for the next decade. Climate risk has moved beyond environmental rhetoric, it is now a strategic imperative requiring pragmatic and structured action. Historically perceived as a distant concern with uncertain financial implications, climate risk often failed to make it onto corporate priority lists. That mindset must change.

Integrating climate risk into ERM frameworks is the most effective way to manage uncertainty and build resilience. This approach strengthens governance, ensures proactive decision-making, and embeds emergency reflexes into organizational culture.

Despite data gaps and modelling challenges, companies must start somewhere. Small steps, such as scenario planning, infrastructure upgrades, and supplier diversification, can evolve into a robust climate risk management system.

Ignoring climate risk is no longer an option. It is not just an environmental issue; it is a financial, operational, and reputational challenge that will define corporate survival and competitiveness in the years ahead. Organizations that act now will not only mitigate risks but also seize opportunities in this increasingly competitive world.
