Climate risks are a financial warning sign

Climate risks are no longer a niche topic—they are an integral part of financial and insurance practice. Today, companies find themselves facing three distinct pressures:

  1. Physical risks posed by heat waves, droughts, floods, and other extreme events directly threaten production, infrastructure, and supply chains. According to Munich Re, natural disasters caused approximately $320 billion in damage in 2024 alone, with over $6.9 trillion in losses incurred over the past few decades—and only just under a third of that was insured.
  2. Transition risks, such as carbon pricing, market shifts, technological disruptions, and regulatory interventions, are changing asset valuations and corporate strategic decisions.
  3. Financial and Regulatory Implications:
    • The European Central Bank (ECB) has identified climate risks as a systemic threat to financial stability and requires banks to incorporate these risks into their credit, capital, and risk models. Starting in July 2025, a “climate factor” will be incorporated into the ECB’s collateral framework—meaning that climate-exposed assets will lose value as collateral.
    • From the perspective of the insurance industry—and Munich Re in particular—rising claims costs due to climate-related events are a key driver. Munich Re has been conducting intensive research on climate risks since the 1970s and warns of increasing claims and liability risks for unprepared companies.

Accordingly, a climate risk analysis is not only environmentally relevant but also economically essential —it determines access to capital, insurance coverage, and long-term competitiveness.

What is a climate risk analysis?

Climate risk analysis refers to the systematic assessment of the impacts of climate change on a company. It takes into account both physical risks (e.g., floods, heat waves, supply chain disruptions) and transition risks (e.g., new regulations, carbon costs, reputational risks).

The goal: an integrated decision-making framework that links climate data, scenarios, and business processes.

Key distinction:
  • Physical risks → direct consequences of climate change, such as extreme weather or infrastructure failures
  • Transition risks → indirect consequences of the transition to a climate-neutral economy (e.g., carbon pricing, technological shifts, market shifts)

Categories of climate risks

Comparison of the two main categories— physical risks and transition risks —presented clearly and concisely, suitable for inclusion in blog posts or slides. Content for each category listed as bullet points (based on a competitor’s structure).

Physical risks

Direct impacts of climate change on locations, assets, and supply chains; acute (event-driven) or chronic (long-term changes).

  • Heat waves – Loss of productivity, cooling and water requirements, quality issues.
  • Extreme storms – Damage to buildings/facilities, business interruptions.
  • Flooding – Logistics disruptions, damage to goods and warehouses, and longer recovery times.
  • Landslides – Threats to transportation routes, sites, and supply routes.
  • Rising sea levels – Location risks in coastal regions, long-term adaptation investments.
Transition risks

Risks arising from political, legal, technological, and societal changes during the transition to a net-zero economy.

  • CO₂ Pricing & Regulation – CSRD/ESRS, EU Taxonomy, Supply Chain Act → Costs & Disclosure Requirements.
  • Climate Policy & Market Signals – Incentive frameworks, standards, and labeling are changing demand and competitive dynamics.
  • Consumer behavior – Preference for climate-friendly products; reputation and revenue risks.
  • Technological changes – Replacement of CO₂-intensive processes; CAPEX requirements & stranded assets.
  • Financing & Insurance – Banks and the ECB are incorporating climate risks; insurers are adjusting premiums and coverage.

Regulatory Framework: CSRD, ESRS & TCFD

Regulatory requirements are making climate risk analyses increasingly mandatory:

  • CSRD & ESRS E1: Companies must systematically identify, assess, and report on climate risks.
  • TCFD (Task Force on Climate-related Financial Disclosures): an international standard for climate risk reporting that is now widely required.
  • EU Taxonomy: explicitly requires the assessment of physical and transitional risks.
  • ECB Guidelines & Banking Supervision: Financial institutions must incorporate climate risks into their credit and portfolio assessments.

Note: The ongoing omnibus procedure of the European Union (trilogue negotiations) is currently still causing uncertainty, for example regarding definitions, reporting requirements, and transition periods. Companies should therefore view their climate risk analyses as a dynamic process and review them regularly once the final decisions have been published.

The 6 Steps to a Successful Climate Risk Analysis

1. Define the business context and objectives

  • Identify relevant locations, processes, and products
  • Clarify strategic importance (financing, reputation, supply chain)
  • Set time horizons (2030, 2050)

2. Select climate data & scenarios

  • Use of IPCC, NGFS, or DWD data
  • Model scenarios (1.5°C, 2°C, >3°C)
  • Take regional climate models into account

3. Risk Identification

  • Physical risks: storms, heat, flooding, drought
  • Transition risks: CO₂ pricing, regulations, market shifts
  • Thinking ahead to opportunities: new products, innovations, efficiency gains

4. Risk Analysis & Assessment

  • Combine probability of occurrence and loss amount
  • Quantitative methods (e.g., Monte Carlo simulations)
  • Qualitative expert estimates for areas of uncertainty

5. Action Plan

  • Adaptation measures (e.g., flood protection, supply chain diversification)
  • Alignment with climate targets and transformation plans (SBTi, CSRD)
  • Integration into existing risk management systems

6. Reporting & Monitoring

  • Integration into CSRD reporting
  • Regular Updates & Rebaselining
  • Internal Communication to the Executive Board, Supervisory Board, and Employees

6 Steps in Climate Risk Analysis

Detailed step-by-step diagram. Clear bullet points, practical instructions, and color-coding for each step. Please include timeframes as a separate note below the diagram.

Step 1 · Context & Objectives

The foundation of the entire analysis: determining what is being examined and why.

  • Define the scope – Identify locations, supply chains, business units, and products.
  • Define objectives – Regulatory compliance, investor expectations, strategic resilience.
  • Establish governance – Establish responsibilities and processes for risk management.
Step 2 · Climate Data & Scenarios

The quality of the analysis depends on the data and scenarios.

  • Select data sources – IPCC, NGFS, DWD; take region-specific data into account.
  • Develop scenarios – Take into account different climate pathways (1.5 °C, 2 °C, >3 °C).
  • Ensure transparency – Openly document assumptions and uncertainties.
Step 3 · Risk Identification

A systematic compilation of potential risks.

  • Identifying physical risks – Heat waves, floods, droughts, storms, sea level rise.
  • Analyzing transition risks – Regulatory requirements, market trends, technological changes.
  • Identifying opportunities – Efficiency gains, new products, better financing terms.
Step 4 · Evaluation & Quantification

Make risks measurable and comparable.

  • Select methods – Heat maps, sensitivity analyses, simulations.
  • Determine the financial implications – Impact on costs, profits, investments, and insurability.
  • Define materiality – Set thresholds and priorities.
Step 5 · Measures & Integration

Develop concrete actions and embed them within the company.

  • Plan adaptation measures – Flood protection, heat resilience, diversifying supply chains.
  • Strategic Alignment – Climate targets, SBTi, climate transformation plans (BAFA Module 5).
  • Prepare the organization – Define roles, train employees, and involve suppliers.
Step 6 · Reporting & Monitoring

Continuously monitor, report, and adjust.

  • Comply with reporting requirements – Report in accordance with CSRD/ESRS and TCFD.
  • Monitor key performance indicators – Implement KPIs and tools, ensure data quality.
  • Schedule update cycles – Regular reviews, adjustments as needed.

Common pitfalls—and how to avoid them

  • Underestimating Scope 3: Supply chain risks often account for more than 70% of emissions.
  • Focusing only on physical risks: Transition risks are often more financially significant.
  • A one-time analysis rather than a continuous process: Climate risks evolve dynamically.
  • Lack of governance support: Without a board resolution, the analysis will have no effect.

Best Practice: Climate risks belong in the central risk management framework —not in a standalone sustainability report.

Deep Dive: Transition Risks in Detail

While physical risks are often visible and have an immediate impact, transition risks unfold more subtly—and can have even greater economic consequences for companies. They arise from the global transition to a climate-neutral economy and affect nearly all industries.

Key drivers of transition risks:

  • Regulatory measures: Introduction of carbon pricing, stricter emission limits, new reporting requirements (CSRD, EU Taxonomy, Supply Chain Act).
  • Market shifts: Customers and business partners are increasingly favoring climate-friendly products and services. Companies that fail to respond are losing market share.
  • Technological disruptions: Decarbonization technologies, renewable energy, electric mobility, and circular economy models are replacing established processes.
  • Financial risks: Banks and investors are taking an increasingly critical view of business models exposed to climate risks. Companies without a climate strategy face less favorable financing terms or lose access to capital.
  • Reputational risks: Stakeholders are demanding transparency. Companies that fail to meet their climate commitments risk a massive loss of trust.

Example: An energy-intensive manufacturing company might not face an immediate risk of flooding, but could still run into trouble if rising CO₂ prices cause operating costs to skyrocket and competitors switch to lower-emission technologies early on.

Conclusion: Climate risk analysis as a strategic lever

A thorough climate risk analysis is more than just a regulatory requirement. It is a strategic management tool designed to:

  • to ensure the company's resilience
  • Reliably meet the requirements of the CSRD and ESRS
  • Convincing investors, banks, and insurers
  • Seizing the opportunities of the transition to a climate-neutral economy
