Climate risk assessments are a core component of corporate risk management, strategy, and disclosure. Multiple ESG disclosure frameworks exist to evaluate corporate risks, and their implementation depends on corporate dependencies, sector, and regional legislations.
Among the most used frameworks are the Task Force on Climate-related Financial Disclosures (TCFD) and International Sustainability Standards Board (IFRS) S2, which now expect companies to systematically identify, assess, and manage climate-related risks and opportunities.
This guide sets out a clear, step-by-step approach to conducting a climate risk assessment that is both practical and aligned with most frameworks.
Step 1: Define scope, boundaries, and governance
The first step in a climate risk assessment is to clearly establish what the assessment will cover and how it will be governed. This involves defining the organizational boundaries (such as subsidiaries, assets, and supply chain components), as well as the geographical areas and sectors under review.
It is equally important to define the time horizons for analysis, typically split into short (0-3 years), medium (3-10 years), and long-term (+10 years) periods, to capture both immediate operational risks and longer-term strategic shifts.
At the governance level, responsibility for climate risk should be assigned to senior leadership, ensuring accountability is embedded within corporate decision-making structures rather than treated as a standalone technical exercise. This step ensures clarity, consistency, and alignment across the organization.
Step 2: Identify climate risks and opportunities
This step focuses on systematically identifying the full range of climate-related risks and opportunities that could affect the organization.
Risks are typically grouped into physical risks (such as extreme weather events, flooding, heat stress, and long-term climatic shifts) and transition risks (including regulatory changes, carbon pricing, market evolution, and technological disruption).
In addition to risks, organizations should also identify opportunities, such as new low-carbon products, energy efficiency gains, or access to green finance. The objective is not to list every possible risk, but to focus on those that are material to the business model, operations, and value chain. This forms the foundation for all subsequent analysis.
Step 3: Assess exposure
Once risks have been identified, the next step is to understand where the organization is exposed to them. This involves mapping physical assets, operations, and supply chains against climate hazards such as flood zones, heat stress areas, water scarcity regions, and coastal vulnerability.
Geographic information systems (GIS), climate datasets, and hazard maps are often used to support this process. The purpose of this step is to establish a clear spatial and operational understanding of exposure—identifying which facilities, suppliers, or markets are located in high-risk areas and how widespread that exposure is across the business.
An approach for mapping risks against business footprint requires listing:
- Physical assets (sites, infrastructure, logistics routes)
- Supply chain dependencies
- Key markets and customer bases
This information could be obtained from available datasets such as:
- Flood and hazard maps
- Climate projections (e.g., temperature, precipitation)
- Satellite and geospatial data
The objective is to determine which assets and operations are exposed to which hazards.
Step 4: Assess vulnerability and adaptive capacity
Exposure alone does not determine risk; vulnerability determines how severely an asset or operation will be affected. This step evaluates the sensitivity of assets and systems to climate hazards and their ability to withstand or recover from them.
Factors such as design standards, age and condition of infrastructure, redundancy of systems, and availability of contingency measures are considered. For example:
- Asset design and condition
- Existing protection measures (e.g., drainage, cooling systems)
- Operational flexibility and redundancy
- Emergency response and recovery capacity
Equally important is adaptive capacity—how quickly and effectively an organization can respond to disruptions. Two assets exposed to the same hazard may have very different risk profiles depending on their resilience and preparedness. This step highlights how well an organization can withstand and respond to climate impacts.
Step 5: Analyze impacts using climate scenarios
This step translates risk into measurable impacts using scenario analysis, which is a core requirement under both TCFD and IFRS S2. Scenario analysis involves assessing how different climate futures—such as low-emission (1.5–2°C) and high-emission (3–4°C) pathways—could affect operations, finances, and supply chains.
Impacts may include direct physical damage, operational downtime, increased costs, reduced revenue, or supply chain disruption. This step is particularly important because it introduces uncertainty into decision-making and allows organizations to test the resilience of their strategy under different future conditions.
Step 6: Prioritize risks and define mitigation actions
After impacts have been assessed, risks must be prioritized based on their likelihood and severity, as well as their strategic and financial materiality. This helps organizations focus resources on the most significant risks rather than treating all risks equally.
Once prioritization is complete, mitigation measures are developed. These may include engineering solutions (such as flood protection or cooling systems), operational adjustments (such as maintenance planning or supply chain diversification), or strategic changes (such as relocation or business model adaptation). The aim is to move from analysis to action by clearly linking risks to practical responses.
Step 7: Integrate intThe final step is where most assessments fail—integration.
The final step is integration, which is often the most important but also the most overlooked. Climate risk findings must be embedded into corporate strategy, enterprise risk management systems, capital planning, and financial decision-making processes.
This ensures that climate considerations influence investment decisions, budgeting, and long-term planning. In parallel, organizations should align outputs with disclosure requirements, ensuring transparency in governance, risk management, strategy, and metrics. Regular monitoring and updates are essential, as climate risk is dynamic and evolves over time. This step transforms the assessment from a one-off exercise into an ongoing management process.
