Climate-Related Risks: Assessing and Managing Financial Risks Associated with Climate Change

Introduction

Climate change is no longer a distant or abstract concern, it is a present and intensifying global challenge with significant economic and financial implications. Across the globe, extreme weather events such as floods, wildfires, hurricanes, and prolonged droughts are becoming more frequent and severe, disrupting communities, damaging infrastructure, and impacting entire economies. For the financial sector, this translates into a range of climate-related risks that can materially affect asset values, business continuity, creditworthiness, and insurance liabilities.

Climate-related financial risks are broadly categorised into three types: physical risks, transition risks, and liability risks. Physical risks arise from the direct impact of climate-related events, such as storms and rising sea levels. Transition risks emerge from the global shift toward a low-carbon economy, including changes in policy, regulation, technology, and consumer behaviour. Liability risks, though less immediately visible, involve potential legal actions against companies that fail to adequately manage or disclose their climate exposures.

This article focuses on how these risks, particularly physical risks, are affecting the financial services industry, with a specific emphasis on the insurance sector. As natural catastrophes escalate in frequency and severity, insurers are experiencing rising claim volumes and costs, pressuring underwriting models, capital reserves, and overall profitability. Simultaneously, regulatory expectations are evolving, requiring financial institutions to integrate climate risk assessment into governance, risk management, and disclosures.

The goal of this article is to provide finance, insurance, and risk professionals with a clear and comprehensive understanding of:

1. The different types of climate-related risks and how they manifest financially
2. The growing impact of extreme weather events on insurance claims and risk modelling
3. Emerging tools, strategies, and frameworks for climate risk assessment and management
4. Regulatory developments and disclosure requirements shaping corporate responses
5. Opportunities for innovation and leadership in managing climate risks effectively

With the growing recognition that climate change is a systemic risk, it is imperative that organisations move beyond reactive measures and adopt proactive, data-driven, and forward-looking strategies to assess, mitigate, and disclose their climate-related exposures. This CPD article equips readers with foundational insights and practical guidance to support informed decision-making in an era of increasing climate uncertainty.

Understanding Climate-Related Financial Risks

As the effects of climate change intensify, financial institutions are increasingly recognising the need to understand and address the diverse risks it poses. These risks are complex, interrelated, and material, capable of disrupting markets, damaging assets, and altering the global financial landscape. Broadly, climate-related financial risks are categorised into three primary types: physical, transition, and liability risks. Each presents distinct challenges and requires tailored management strategies.

a. Types of Climate Risks

Physical Risks

These arise directly from climate-related event and can be further divided into the following categories:

1. Acute physical risks: Sudden, severe weather events such as hurricanes, floods, wildfires, and heatwaves. These events can cause immediate and substantial damage to infrastructure, agriculture, homes, and businesses, resulting in large insurance claims and operational disruptions.
2. Chronic physical risks: Long-term shifts in climate patterns, such as rising sea levels, increased average temperatures, and changing rainfall patterns. These can erode asset values over time and reduce the habitability or economic viability of certain regions.
3. Transition Risks: Transition risks stem from the global shift towards a low-carbon economy. This transition involves regulatory changes, evolving market preferences, and technological innovation aimed at reducing greenhouse gas emissions. Key components include the following:
4. Policy and legal changes: Carbon pricing, emissions targets, climate-related disclosure regulations.
5. Market shifts: Devaluation of carbon-intensive assets (e.g., oil reserves), changes in consumer demand.
6. Technology: Emergence of cleaner technologies that disrupt existing business models.

Financial institutions and corporations exposed to high-carbon industries face the risk of asset devaluation, stranded investments, and reputational damage if they do not adapt.

Liability Risks

These involve potential litigation or legal claims resulting from:

1. Failing to mitigate or disclose climate risks
2. Causing environmental harm through negligence
3. Misleading investors about climate-related exposures.

As climate awareness grows, legal precedents are forming globally, and companies face rising expectations to demonstrate due diligence in climate risk management.

b. Pathways of Financial Impact

Climate-related risks affect financial institutions through multiple channels:

1. Asset impairment: Properties, infrastructure, and business operations located in high-risk zones may suffer damage or lose value. For example, a coastal hotel chain might face higher insurance premiums and asset devaluation due to flood risks.
2. Credit risk: Borrowers operating in vulnerable sectors or regions may experience income volatility, leading to loan defaults. Mortgage-backed securities could also be affected if property values fall due to climate threats.
3. Market risk: Climate shocks can lead to price volatility in commodities, equities, and bonds. For example, droughts can reduce agricultural output, spiking food prices and affecting related financial instruments.
4. Operational risk: Disruptions to supply chains, workforce availability, or IT systems from extreme weather can halt operations, impact earnings, and increase costs.
5. Reputational risk: Failure to address or disclose climate risks can lead to investor dissatisfaction, loss of consumer trust, or regulatory penalties.

c. Real-World Examples

Several recent climate-related disasters highlight the magnitude of financial impact:

1. Hurricane Katrina (2005): Caused over $125 billion in damages in the U.S. and became one of the costliest natural disasters in history. Insurers faced an overwhelming number of claims, prompting revisions to catastrophe modelling and underwriting practices.
2. Australian Bushfires (2019–2020): Resulted in billions in damages, disrupted local economies, and led to significant insurance payouts. The fires also exposed the vulnerabilities of rural infrastructure and the insurance protection gap in high-risk zones.
3. European Floods (2021): Flash floods in Germany and Belgium caused extensive damage to residential and commercial property. Total insured losses exceeded €10 billion, raising concerns about floodplain management and infrastructure resilience.

In each case, the events not only led to massive insured losses but also forced governments, regulators, and financial institutions to reassess how climate-related risks are quantified and managed.

Understanding the multi-faceted nature of climate-related financial risks is the first step toward effective mitigation. The next sections will explore how these risks are impacting specific sectors, particularly the insurance industry, and how firms can adopt robust tools and strategies for risk management and resilience.

Sectoral Focus: Impact on the Insurance Industry

The insurance industry stands on the frontlines of climate-related financial risk. As the primary mechanism for transferring and managing risk, insurers are uniquely exposed to the increasing frequency and severity of natural disasters driven by climate change. This exposure is testing the industry’s traditional models, assumptions, and resilience, and it is reshaping the future of insurance underwriting, pricing, and regulation.

a. Rising Claims and Costs

The financial toll of climate change is most immediately felt through the increasing volume and cost of insurance claims. According to data from Swiss Re and Munich Re, global insured losses from natural catastrophes have more than doubled over the past two decades, with several recent years exceeding $100 billion in insured losses.

Climate-related disasters such as the wildfires in California and Australia, floods in Europe and Asia, and hurricanes in the Atlantic Basin have all contributed to this sharp rise in claims. In response, insurers are facing higher reinsurance costs, more volatile loss ratios, and tighter profit margins. Some have withdrawn coverage from high-risk regions or significantly raised premiums, making insurance increasingly unaffordable or unavailable for vulnerable communities.

This trend introduces a wider systemic concern: the growth of the insurance protection gap, which is the difference between total economic losses and the portion that is insured. As more regions become uninsurable due to climate risk, governments may be forced to intervene, raising questions about public-private risk sharing and financial stability.

b. Challenges in Risk Modelling

Traditional actuarial models used by insurers rely heavily on historical loss data to predict future risk. However, climate change undermines the reliability of these models because past weather patterns no longer accurately predict future conditions. The non-linear and evolving nature of climate change introduces deep uncertainty into risk projections.

This can be attributed to the following factors by way of example:

• A “1-in-100-year flood” might now occur every 10 or 20 years.
• Droughts may become more prolonged or shift in geographic pattern.
• Wildfire seasons may lengthen and intensify unpredictably.

Insurers are thus being forced to augment traditional models with the following considerations:

• Climate science data (e.g., from IPCC or national meteorological agencies)
• Advanced catastrophe models that incorporate climate scenarios
• AI and machine learning to detect emerging patterns
• Geographic information systems (GIS) and satellite data for risk mapping

However, these tools are not uniformly available or understood across the industry. Smaller insurers and those in developing markets often lack the resources to invest in advanced modelling capabilities, leaving them more vulnerable to systemic shocks.

c. Regulatory and Rating Agency Responses

Recognising the growing threat climate change poses to financial stability, regulators and rating agencies are stepping in to require greater transparency, preparedness, and integration of climate risk into governance and risk management frameworks.

Key developments include the following:

1. Task Force on Climate-related Financial Disclosures (TCFD): Now widely adopted globally, TCFD encourages insurers and financial institutions to disclose climate risks across four pillars including governance, strategy, risk management, and metrics/targets.
2. Prudential Regulation Authority (PRA) in the UK: Has mandated that insurers embed climate risks into their risk management frameworks and perform climate scenario analysis.
3. EU Solvency II updates: Require insurers to assess and disclose climate risks, with plans to incorporate climate scenario analysis into solvency assessments.
4. Rating agencies like Moody’s, S&P, and Fitch: Now include ESG and climate risk considerations in credit ratings. An insurer’s ability to manage climate risk can influence its rating and access to capital.

These evolving expectations are driving the insurance industry toward more rigorous, forward-looking, and transparent approaches to climate risk.

Looking Ahead

The insurance industry is at a crossroads. On one hand, climate change poses existential challenges to traditional business models and risk pools. On the other hand, it offers a powerful incentive for innovation in risk assessment, product design, and customer engagement.

As this article will explore further, insurers must not only refine their modelling capabilities but also collaborate across industries and borders, invest in adaptation and resilience, and lead by example in climate governance and disclosure. Those who move early and decisively may turn risk into opportunity, while those who delay may find themselves unprepared for a rapidly changing risk landscape.

Financial Sector Responses and Tools for Risk Management

As climate-related risks grow in scale and complexity, the financial sector is actively developing and deploying new tools and strategies to assess, manage, and mitigate their impacts. From scenario analysis and advanced data modelling to sustainable finance instruments and innovative insurance solutions, firms are increasingly embracing a multi-layered approach to climate risk management.

a. Scenario Analysis and Stress Testing

One of the most important tools in climate risk assessment is scenario analysis; a forward-looking approach that evaluates the resilience of a business under different climate-related pathways. Unlike traditional risk assessments, which rely on historical data, scenario analysis projects potential outcomes based on varying assumptions about:

• Future levels of global warming
• Policy and regulatory responses (e.g. carbon pricing)
• Technological developments
• Consumer behaviour shifts

The Network for Greening the Financial System (NGFS) has developed standardised climate scenarios to support regulators and financial institutions. These include:

1. Orderly Transition: Early, coordinated action to limit warming to 1.5–2°C.
2. Disorderly Transition: Late, uncoordinated action leading to economic disruption.
3. Hot House World: No significant climate action, resulting in severe physical risks.

Many central banks and regulators now require financial institutions to conduct climate stress testing using such scenarios. For example, the Bank of England’s Climate Biennial Exploratory Scenario (CBES) framework tests how banks and insurers would fare under a range of climate conditions.

These exercises help organisations understand their exposure to both physical and transition risks, assess portfolio vulnerabilities, and develop risk mitigation strategies.

b. Climate Risk Modelling and Data Tools

Assessing climate-related financial risk requires reliable data, sophisticated models, and the integration of climate science into risk systems. Several cutting-edge tools are emerging to fill this need including the following:

• Geospatial and Satellite Data: High-resolution mapping of floodplains, wildfire zones, sea-level rise exposure, and temperature trends. This helps insurers and banks assess location-specific risk to properties, infrastructure, and supply chains
• Catastrophe (Cat) Modelling: Used extensively in the insurance industry, these models simulate losses from extreme events such as hurricanes or earthquakes. Cat models are now being updated with climate-adjusted parameters, allowing for more accurate long-term risk pricing.
• AI and Machine Learning: Algorithms that detect trends and correlations in vast datasets, which are useful in identifying early warning signs of climate risk exposure or asset performance under climate stress.
• Climate Risk Platforms: Providers like Jupiter Intelligence, Cervest, Four Twenty Seven, and S&P Global offer integrated platforms that combine climate data, analytics, and reporting tools.

These technologies empower financial firms to move from reactive risk management to proactive climate resilience planning.

c. ESG Integration and Sustainable Finance

Climate risk is now a core pillar of the Environmental, Social, and Governance (ESG) framework that guides sustainable investing. Investors and regulators alike expect firms to quantify and disclose their climate exposures, and to align capital allocation with sustainability objectives.

Green and Transition Finance Instruments

1. Green Bonds: Debt instruments financing projects with environmental benefits (e.g., renewable energy, clean transport).
2. Sustainability-Linked Bonds and Loans: Interest rates tied to achieving climate-related KPIs.
3. Transition Finance: Supports carbon-intensive companies in gradually reducing emissions without penalising them for their current footprint.
4. Climate-Aligned Investment Portfolios: Financial institutions are increasingly committing to net-zero portfolios by 2050, in line with the Paris Agreement. Portfolio alignment tools assess exposure to climate risks and model decarbonisation pathways.

In this evolving context, climate risk is no longer viewed solely as a compliance issue, but as a strategic investment consideration with implications for long-term value creation.

d. Insurance Innovations

Insurers are developing innovative products to address both the growing demand for climate risk protection and the limitations of traditional insurance models.

1. Parametric Insurance
2. Pays out a predefined sum based on a trigger event (e.g., wind speed, rainfall level) rather than assessed damages.
3. Offers faster payouts, greater transparency, and reduced administrative costs.
4. Widely used in agriculture, disaster relief, and weather-sensitive sectors.

• Climate Risk Pools
• Regional or international risk-sharing mechanisms, such as the African Risk Capacity (ARC) or Caribbean Catastrophe Risk Insurance Facility (CCRIF).
• Help vulnerable countries manage disaster risk through pooled insurance backed by donor funding and reinsurance.

• Microinsurance
• Low-cost insurance tailored for individuals and small businesses in developing countries.
• Supports resilience among populations most affected by climate change but least able to afford conventional insurance.
• These innovations reflect a shift towards inclusive and anticipatory insurance models, reinforcing the role of insurance not only as a financial safety net but also as a driver of adaptation and resilience.

The rapid evolution of risk management tools underscores the financial sector’s commitment to addressing climate risk. Yet, these tools are most effective when embedded within a comprehensive risk governance framework, aligned with strategic decision-making, and supported by accurate, forward-looking data.

The next section explores how corporations, beyond the financial sector, are integrating climate risk into their enterprise risk management strategies.

Corporate Risk Management Strategies

As the financial implications of climate change become more apparent, corporations across all sectors are under increasing pressure to integrate climate-related risks into their enterprise risk management (ERM) frameworks. This goes beyond basic compliance; it involves embedding climate awareness into strategic planning, operational resilience, and corporate governance to safeguard long-term value.

a. Enterprise Risk Management (ERM) and Climate Integration

Climate change presents a cross-cutting risk that affects virtually every aspect of an organisation’s operations, from supply chains and infrastructure to customers and capital markets. As such, it must be addressed not as a siloed environmental issue, but as an integral part of ERM.

Key strategies for integrating climate into ERM include:

• Board and Executive Oversight: Boards must take active responsibility for overseeing climate risk. This includes appointing directors with climate expertise and ensuring management embeds climate into decision-making processes.
• Materiality Assessment: Organisations must identify which climate-related risks are material to their business, based on location, industry, customer base, and regulatory exposure.
• Scenario Planning: Like financial institutions, corporates are increasingly using scenario analysis to assess potential climate impacts under different warming pathways and policy environments.
• Cross-functional Collaboration: Climate risk management often spans risk, finance, sustainability, operations, legal, and strategy teams. A coordinated approach helps ensure climate is considered across all decision-making levels.

Integrating climate into ERM enables organisations to better anticipate disruptions, reduce financial exposure, and build competitive advantage through resilience.

b. Climate Disclosure and Reporting

Transparency around climate-related risks and opportunities is now a critical expectation from investors, regulators, and stakeholders. Climate disclosure enables organisations to demonstrate preparedness and align with global best practices.

The most widely adopted framework for climate-related disclosure is the Task Force on Climate-related Financial Disclosures (TCFD). It recommends disclosures in the following four core areas:

1. Governance: The organisation’s oversight and management of climate risk.
2. Strategy: The actual and potential impacts of climate risks on business strategy.
3. Risk Management: How climate risks are identified, assessed, and managed.
4. Metrics and Targets: The data used to measure climate risks and progress toward climate goals (e.g. emissions, energy use, climate VaR).

In 2024, the International Sustainability Standards Board (ISSB) launched the IFRS S2 standard, consolidating and building upon TCFD and other reporting frameworks. This new standard is expected to harmonise global climate reporting and accelerate the integration of sustainability into capital markets.

Regulatory bodies are also stepping up:

• The EU’s Corporate Sustainability Reporting Directive (CSRD) mandates climate-related reporting for thousands of companies.
• The U.S. Securities and Exchange Commission (SEC) has proposed enhanced climate disclosure rules.
• APAC jurisdictions like Singapore, Japan, and New Zealand are implementing mandatory reporting for listed firms.

Organisations that proactively engage with climate disclosure are better positioned to attract investment, meet stakeholder expectations, and demonstrate climate resilience.

c. Risk Mitigation Strategies

Once climate risks are identified and disclosed, the next step is mitigation, taking concrete actions to reduce financial exposure and improve adaptive capacity as follows:

Physical Adaptation Investments

• Retrofitting facilities for flood or heat resistance
• Relocating critical infrastructure from high-risk zones
• Enhancing building insulation and energy systems

These investments protect business continuity and often yield long-term cost savings.

Diversification

• Geographic diversification of operations and supply chains reduces vulnerability to localised climate events.
• Product and market diversification helps businesses adapt to shifting consumer behaviour due to climate awareness.

Insurance and Risk Transfer

• Companies can purchase traditional or parametric insurance products to protect assets.
• Insurance-linked securities (ILS), such as catastrophe bonds, provide a mechanism to transfer climate risk to capital markets.

Supplier Engagement

• Organisations are increasingly assessing and improving the climate resilience of their supply chains.
• Supplier audits, training, and climate scenario assessments are now part of procurement processes.

By embedding these risk mitigation strategies, companies can not only reduce their vulnerability to climate events but also create value through operational efficiency, brand reputation, and stakeholder trust.

Climate change is not a standalone risk, it is a risk multiplier that intersects with operational, reputational, legal, and strategic concerns. Organisations that treat it as a strategic priority and integrate it into their enterprise risk management frameworks are more likely to thrive in an increasingly volatile climate and regulatory environment.

Opportunities Amid Climate Risk

While the financial risks associated with climate change are significant, they also come hand-in-hand with unprecedented opportunities for forward-thinking organisations. As global markets shift toward sustainability and resilience, companies and financial institutions that act decisively can gain competitive advantages, tap into emerging markets, and create long-term value.

a. Innovation in Products and Services

The rising demand for climate resilience is spurring innovation across sectors as follows:

• Green technology: From carbon capture and renewable energy to electric vehicles and low-carbon building materials, there is enormous growth potential in technologies that reduce emissions or enhance climate resilience.
• Climate advisory and risk analytics: As organisations seek to navigate complex climate risks, there’s increasing demand for climate-related consulting, risk modelling, and scenario planning services. Firms that develop proprietary tools or offer third-party solutions stand to benefit.
• Insurance innovation: As covered earlier, parametric insurance, microinsurance, and catastrophe bonds are filling gaps in protection and opening up new markets, especially in vulnerable or underserved regions.
• Climate adaptation infrastructure: Investment in water management, resilient urban planning, and disaster-proof infrastructure is increasing. These projects not only reduce long-term economic losses but also present new avenues for public-private partnerships.

b. Capital Allocation and Sustainable Investment

The rise of sustainable finance has created new investment categories:

• Green bonds and ESG funds continue to attract capital, providing lower-cost financing for climate-positive projects.
• Institutional investors are increasingly using climate metrics (like carbon intensity or alignment with the Paris Agreement) to screen and select investments.
• Asset managers with strong ESG integration and climate risk frameworks are positioning themselves to attract climate-conscious capital.

Climate-related risk assessment is becoming a core part of fiduciary duty, not just a reputational consideration.

c. Competitive Differentiation

Companies that lead on climate resilience and transparency are increasingly being rewarded by:

• Investors, who see them as lower-risk, future-proof bets
• Customers, who favour environmentally responsible brands
• Regulators, who may offer incentives or reduce compliance burdens
• Employees, who prefer to work for values-driven organisations

Taking early and decisive action on climate-related risks can thus provide a first-mover advantage, positioning a firm not only to survive in a changing climate, but to lead.

Climate risk is not solely a burden, it is a powerful driver for innovation, strategic positioning, and long-term value creation. In the next section, we will explore the remaining challenges that still hinder progress in climate risk management.

Challenges and Gaps

Despite growing awareness and progress in climate risk management, several critical challenges and systemic gaps continue to hinder effective response across the financial and corporate sectors. These challenges must be acknowledged and addressed to enable scalable, consistent, and impactful climate risk strategies.

a. Data and Modelling Limitations

One of the most significant barriers is the lack of reliable, granular, and consistent climate data. Many organisations still struggle to:

• Access high-resolution, location-specific data on physical risks
• Forecast long-term impacts with confidence due to scientific uncertainty
• Translate climate science into financially material metrics that can be used in investment and risk decisions

Furthermore, there is a shortage of standardised methodologies for modelling and valuing climate-related financial risks, particularly in emerging markets and smaller firms with limited resources.

b. Inconsistent Regulatory Landscape

The regulatory environment for climate risk disclosure and governance is fragmented globally. While some jurisdictions have introduced mandatory reporting (e.g., EU CSRD, IFRS S2), others remain voluntary or lag behind. This inconsistency can leads to the following:

• Reporting fatigue among multinational organisations
• Uneven levels of transparency and comparability
• Difficulties for investors trying to assess and compare climate risk exposures across markets

Greater global coordination and convergence in standards are needed to ensure meaningful and comparable disclosures.

c. Skills and Capacity Gaps

Effective climate risk management requires a blend of expertise across climate science, data analytics, risk management, and financial modelling. However, many organisations face the following challenges:

• A shortage of qualified professionals with interdisciplinary climate finance skills
• Inadequate training and awareness at board and senior management levels
• Limited internal capacity to assess, interpret, and act on climate risk data

Upskilling and cross-sector collaboration will be essential to bridge these gaps.

As climate risks continue to escalate, closing these gaps will be critical. The final section of this article offers a call to action for professionals and organisations to take proactive steps toward building climate resilience.

Conclusion

Climate-related financial risks are no longer hypothetical; they are real, accelerating, and already reshaping the financial, insurance, and corporate landscapes. From the mounting costs of extreme weather events to the pressures of regulatory reform and shifting investor expectations, organisations across all sectors must confront the reality that climate risk is financial risk.

This article has explored how climate risks manifest physically, transitionally, and legally, and how they impact insurance claims, asset values, credit exposure, and operational continuity. It has also highlighted the innovative tools, frameworks, and financial instruments emerging in response, alongside the growing regulatory push for transparency and resilience.

While challenges remain, particularly around data, regulation, and skills, the opportunities for proactive leaders are immense. By integrating climate risk into governance, risk management, and disclosure practices, organisations can not only reduce exposure but also unlock value through innovation, investment, and long-term sustainability.

Finance, risk, and insurance professionals are uniquely positioned to help shape a more climate-resilient future. With their expertise in assessing uncertainty, managing exposure, and planning for long-term outcomes, they can guide organisations through the complexities of climate-related challenges. This isn’t just about ticking regulatory boxes; it’s about understanding how climate change could impact business performance, supply chains, investment portfolios, and client needs.

By taking a thoughtful approach to scenario planning, improving the quality of climate-related disclosures, and investing in the right tools and talent, professionals can help their organisations adapt and remain competitive. After all, while the risks are growing, so too are the opportunities for those who are prepared.
