Different Types of Climate Risks

Environmental issues and lack of water

Climate risks can be broadly categorized into physical risks, transition risks, and liability risks. Each type of risk encompasses various specific factors that can impact businesses, economies, and societies. Understanding these risks is crucial for effective climate risk management and adaptation strategies.

1. Physical Risks

Physical risks arise from the direct impact of climate change on the environment. These risks can be divided into acute and chronic risks:

  • Acute Physical Risks: Event-driven risks associated with extreme weather events. Examples include:
    • Hurricanes and Typhoons: Intense tropical storms causing extensive damage to infrastructure and supply chains.
    • Floods: Heavy rainfall, river overflow, and storm surges leading to flooding, damaging properties and agricultural lands.
    • Wildfires: Increased temperatures and prolonged dry periods leading to frequent and severe wildfires.
    • Heatwaves: Extreme heat events affecting human health, labor productivity, and energy demand for cooling.

  • Chronic Physical Risks: Long-term changes in climate patterns, such as:
    • Rising Temperatures: Sustained increases in average temperatures affecting crop yields, water availability, and energy consumption patterns.
    • Sea Level Rise: Gradual increase in sea levels leading to coastal erosion, land loss, and increased flooding risks.
    • Changes in Precipitation Patterns: Alterations in rainfall causing water scarcity in some regions and increased flooding in others.
    • Ocean Acidification: Increased CO2 absorption by oceans harming marine life, affecting fisheries and ecosystems.

2. Transition Risks

Transition risks are associated with the shift towards a low-carbon economy. These risks can arise from changes in policy, technology, market dynamics, and societal preferences:

  • Policy and Regulatory Risks: Governments implementing policies to mitigate climate change, such as:
    • Carbon Pricing: Introduction of carbon taxes or cap-and-trade systems to reduce greenhouse gas emissions.
    • Emission Regulations: Stricter regulations on emissions from industries and vehicles.

  • Technology Risks: The development and adoption of new technologies disrupting existing industries and business models:
    • Renewable Energy Technologies: Advances in solar, wind, and battery storage technologies affecting fossil fuel industries.
    • Energy Efficiency Improvements: Innovations in energy efficiency reducing demand for traditional energy sources.

  • Market Risks: Shifts in supply and demand as a result of climate change and mitigation efforts:
    • Changing Consumer Preferences: Increased demand for sustainable products and services.
    • Stranded Assets: Investments in fossil fuel infrastructure becoming unprofitable as the world transitions to cleaner energy sources.

  • Reputation Risks: Companies perceived as not addressing climate change adequately facing reputational damage:
    • Consumer Backlash: Negative public perception affecting brand loyalty and sales.
    • Investor Pressure: Investors divesting from companies that do not demonstrate strong climate risk management.

3. Liability Risks

Liability risks arise from the potential for legal action due to climate change impacts or inadequate responses to climate change:

  •    Litigation: Companies facing lawsuits for contributing to climate change or failing to disclose climate risks:
    • Environmental Damage Claims: Legal actions related to pollution, environmental degradation, and health impacts.
    • Failure to Adapt: Lawsuits against companies for not taking adequate measures to mitigate or adapt to climate change, resulting in harm to stakeholders.

Understanding and managing these diverse climate risks is essential for building resilience and ensuring long-term sustainability in a changing climate.

Steps to Assess Physical Climate Risk

A structured approach to assessing physical climate risks involves categorizing them into chronic and acute risks and evaluating their potential impacts on cost, turnover, and the value chain. The process also involves understanding the expected changes in climate risk factors and estimating the overall impact based on future climate scenarios (RCPs).

Step 1: Potential Impact

- Cost: Assess whether the climate risk factor can lead to additional future costs (capital or operational expenditure).
- Turnover: Evaluate if the climate risk factor can have operational effects that impact the company’s ability to generate turnover.
- Value Chain: Determine if the climate risk factors can affect the suppliers or customers of the company, either through additional costs or turnover generation.

Step 2: Expected Change in Climate Risk Factor

For risks identified with potential impact in Step 1, assess their expected development over the asset’s life-time using the RCP scenarios:
- RCP 8.5: Worst-case scenario.
- RCP 4.5: Likely scenario.
- Use best available knowledge if specific developments within the RCP scenarios are not identifiable.

Step 3: Estimated Impact

Based on the assessments from Steps 1 and 2, provide a high-level risk classification of the estimated impact.

Tools and Resources for Assessing Climate Risks

Businesses can utilize various tools and resources to conduct climate risk assessments, such as climate risk indices, scenario analysis, and climate modeling. These resources provide valuable insights into the potential risks that businesses may face, allowing them to develop informed strategies for risk mitigation and adaptation.

Datasources and Tools for Assessing Climate Risks

Steps According to ISO Standard 14091

The EU Taxonomy Delegated Regulation (EU) 2021/2139 ("Climate Delegated Act") requires companies to carry out a "robust climate risk and vulnerability assessment" for their economic activities to achieve taxonomy alignment.

  • As a criterion for a "significant contribution" to the environmental objective of "adaptation to climate change"
  • As a criterion for "do no significant harm" (DNSH) to "adaptation to climate change"

The requirements for a climate risk assessment are the same for both purposes; differences in the criteria concern the implementation of adaptation solutions.



  1. Determining the expected lifespan for each economic activity and identifying investigation objects:

    • For each economic activity, the expected lifespan must be determined. This helps to define the period over which the climate risks should be assessed.
    • Subsequently, the specific objects or areas that will be included in the investigation must be identified. These could be specific projects, facilities, infrastructure, or other relevant units.

  2. Determining climate-related hazards from Appendix A of the Climate Delegated Act (Screening):

    • In this step, the potential climate-related hazards that could affect the economic activities are identified. These hazards can be determined by reviewing Appendix A of the relevant standard (ISO 14091).
    • These hazards include a variety of climate risks, such as extreme weather events, temperature changes, changes in precipitation patterns, and other climate-related factors that could jeopardise economic activity.


  1. Conducting the climate risk assessment:

    • This step involves the actual assessment of the identified climate risks. It examines the likelihood of the identified hazards occurring and their potential impacts on economic activities.
    • The assessment should include both quantitative and qualitative methods to ensure a comprehensive risk evaluation. This includes considering the vulnerability and adaptability of the respective economic activities.

  2. Identifying and assessing adaptation solutions:

    • After assessing the climate risks, adaptation solutions must be identified and evaluated. These solutions are intended to help mitigate or manage the identified risks.
    • The evaluation of the adaptation solutions includes analysing their effectiveness, feasibility, and costs. Strategies are developed to make the economic activities more resilient to the identified climate risks.


There must be comprehensible documentation showing how figures were calculated and how qualitative information is justified.

Documentation of the climate risk assessment:

  • Preparatory steps performed
  • Assessments made
  • Assessment results

If climate risks have been identified: adaptation plan including:

  • Adaptation solutions (systematically assessed for suitability)
  • Timetable for the implementation of adaptation solutions
  • Documentation of already implemented adaptation solutions

Climate Risk Management Strategies

Implementing proactive measures to address material climate risk is crucial for businesses to build resilience and adapt to the changing climate landscape. This involves developing a comprehensive climate risk management plan that outlines specific actions to mitigate identified risks and capitalize on opportunities associated with climate change.

Integrating climate risk management into business operations and decision-making processes is essential for ensuring that climate considerations are embedded into strategic planning, investment decisions, and risk management practices. By incorporating climate risk management into business practices, organizations can enhance their long-term sustainability and competitiveness.

Climate Risk Analysis for Businesses

Analyzing the financial implications of climate risk is essential for businesses to understand the potential costs associated with climate-related events and disruptions. This involves evaluating the direct and indirect financial impacts of climate risk on business operations, including potential losses, increased costs, and changes in market dynamics.

Understanding the long-term effects of climate risk on business sustainability is critical for businesses to make informed strategic decisions and allocate resources effectively.
