A Practical Guide to Climate Risk Assessment:

What Is a Climate Risk Assessment?

A climate risk assessment identifies how climate-related hazards and the broader transition to a lower-carbon economy could affect a specific asset, portfolio, or business operation. It covers two categories of risk.

Physical Climate Risk

Physical risks arise from direct exposure to climate hazards. These fall into two groups:

• Acute hazards: flooding, extreme heat, wildfire, tropical cyclones, drought, and landslides

• Chronic hazards: rising temperatures, sea-level rise, changing precipitation patterns, water stress, and ocean acidification

Climate Transition Risk

Transition risks arise from the global shift to a lower-carbon economy. For businesses and investors, these include:

• Policy and regulatory risk, including exposure to the EU Taxonomy, CSRD, and carbon pricing mechanisms

• Stranded asset risk, where assets lose value as climate-related regulation or physical conditions shift

• Market and reputational risk as investor and stakeholder expectations around climate performance tighten

The two categories are connected. An asset that is highly exposed to physical hazards under future warming scenarios is also likely to face transition pressures as regulatory requirements evolve in response. A credible assessment addresses both.

Climate Risk Reporting Requirements: What the Frameworks Demand

Regulatory requirements now span multiple frameworks. Here is what each requires from a climate risk assessment perspective:

• ISSB S2 (IFRS S2): The global baseline for climate-related financial disclosure, superseding TCFD. Requires scenario analysis under at least two warming pathways and quantitative risk metrics. Mandatory in a growing number of jurisdictions including the UK and Australia.

• EU Taxonomy (CRVA): Requires a Climate Risk and Vulnerability Assessment screening against a defined list of hazards across current and future climate scenarios. One of the most technically demanding requirements in the landscape.

• Paris Alignment: Requires that material physical climate risks are identified and assessed at the asset level.

• CSRD / ESRS E1: Requires large European companies to identify and disclose climate-related risks and their financial impacts.

• SFDR: Requires fund managers to disclose sustainability risks including climate exposure across their investment portfolios.

Regulatory alignment is a key output of a well-structured assessment, but the primary value is understanding and managing the underlying risks, not just reporting on them.

Why Climate Risk Assessment Matters: Protecting What You're Responsible For

The regulatory requirements are real and growing, but the more fundamental reason to assess climate risk is straightforward: climate change is already affecting the value, performance, and insurability of assets and operations across every major sector and geography.

Physical hazards, such as flooding, extreme heat, water stress, wildfire, are no longer tail risks confined to distant time horizons. They are present risks that are already driving valuation impacts, increasing insurance premiums, disrupting operations, and affecting the availability of financing for exposed assets. Investors and lenders that do not understand their exposure cannot price it, manage it, or explain it to their own stakeholders.

Transition risks compound this. As governments tighten carbon pricing, adjust land use policy, and mandate lower-carbon alternatives, assets that appear sound today can become stranded. The pace of regulatory change in some jurisdictions means that transition risk is already a near-term financial consideration, not a long-term scenario.

Organisations that lack visibility of their climate exposure are not just falling short of disclosure requirements. They are making investment, lending, and operational decisions without a complete picture of the risks involved. The consequences range from stranded assets and rising insurance costs to reputational damage and restricted access to capital, and they compound over time the longer action is deferred.

A credible climate risk assessment does not just satisfy a reporting obligation. It gives decision-makers the information they need to protect and manage what they are responsible for.

How to Do a Climate Risk Assessment: The Process Step by Step

Step 1: Define Scope and Asset Locations

Asset-level location data is essential. Climate risk varies significantly over short distances, particularly for hazards like flooding, coastal inundation, and wildfire. Assessments based on sector or country averages will miss this variation and are unlikely to satisfy ISSB S2 or EU Taxonomy CRVA requirements.

Step 2: Screen for Physical Hazard Exposure

Each asset is assessed against a defined set of physical climate hazards. A robust assessment covers 35 or more hazard types across both acute and chronic categories, tied to the precise footprint of each site rather than a regional average. This location-level precision is what separates a meaningful climate risk assessment from a generic indicator, and it is exactly what frameworks such as ISSB S2 and the EU Taxonomy CRVA demand.

Step 3: Assess Transition Risk

Transition risk assessment draws on country-level policy and regulatory inputs. It evaluates exposure to evolving legislation, carbon pricing mechanisms, and market shifts, identifying which assets or business lines face the greatest pressure as economies decarbonise. This step is particularly relevant for organisations with CSRD or ISSB reporting obligations, and for financial institutions with exposure to carbon-intensive sectors.Request a platform demo to see scenario analysis in action.

Step 4: Run Climate Scenario Analysis

Scenario analysis models how risk exposure changes under different warming pathways. ISSB S2 requires assessment under at least two scenarios. Frontierra runs analysis using IPCC-aligned projections across SSP1-2.6, SSP2-4.5, and SSP5-8.5, at the asset location level across near-, medium-, and long-term time horizons. This surfaces which assets are resilient across all futures and which face escalating risk under higher warming trajectories.

Step 5: Interpret Results and Act

Individual asset results are aggregated across the portfolio to identify where risk is concentrated and how it varies across scenarios. The output should not just surface risk, it should provide clear, actionable recommendations so your team knows exactly which assets require attention and what steps to take next.

What Good Climate Risk Assessment Looks Like

Not all assessments are equal. These are the features that distinguish credible, decision-useful analysis.

• Asset-level precision: analysis tied to the precise footprint of each site, not sector averages or regional proxies. Risk can vary significantly between two assets in the same city, let alone the same country.

• Multiple scenarios and time horizons: covering at least a low- and high-emission pathway across near, medium, and long-term periods. A single scenario assessment will not satisfy most disclosure frameworks and risks understating exposure under higher warming trajectories.

• Integrated climate and nature risk: deforestation, biodiversity loss, and ecosystem degradation can amplify physical hazards and create additional financial and regulatory exposure. Organisations that assess climate risk in isolation may be missing a significant part of the picture.

• Intelligible outputs: findings that give decision-makers a clear picture of where risk lies, how it compares across the portfolio, and what actions follow. Data alone is not enough.
