Climate Risk Assessment Framework: Identifying and Managing Transition and Physical Risks

Climate change is no longer a peripheral environmental concern. It is now recognized as a core financial and strategic risk factor influencing capital allocation, regulatory oversight and investor expectations. Organizations across sectors are now required to systematically evaluate how climate related risks impact operations, supply chains and long term enterprise value.

Introduction to Climate Risk Assessment Framework

A structured climate risk assessment framework enables companies to identify exposure to physical and transition risks, quantify financial impact and align mitigation strategies with regulatory expectations. Businesses integrating climate risk analysis into corporate governance and decision making processes are better positioned to safeguard assets, strengthen operational resilience, maintain investor confidence and comply with emerging disclosure standards. 

For organizations seeking integrated support, Aranca supports with Sustainability and Climate Consulting Services including structured methodologies that align climate risk management with enterprise strategy.

Understanding the Importance of a Climate Risk Assessment Framework

A climate risk assessment framework provides a systematic approach to identifying, measuring, prioritizing, and integrating climate related risks into enterprise risk management, financial planning, and strategic decision-making processes. As climate related disclosures increasingly become embedded within frameworks such as TCFD and IFRS S2, organizations are expected to demonstrate how climate risks may materially impact business resilience, asset valuation, capital allocation, and long term enterprise value.

Climate risks are broadly categorized into:

• Physical risks 

• Transition risks

Physical risks include:

• Extreme weather events

• Rising sea levels

• Heat stress

• Flooding

• Supply chain disruptions

• Damage to infrastructure and operational assets

• Water stress and long term shifts in climatic patterns impacting operational continuity

Transition risks arises typically under these categories:

• Policy and Legal

• Technology

• Market

• Reputation

Organizations that fail to evaluate these risks may face asset impairment, stranded investments, higher cost of capital, insurance limitations, operational disruptions, reduced market competitiveness or regulatory penalties. Increasingly, investors and regulators expect businesses to quantify climate related financial exposure using scenario analysis and forward-looking risk methodologies rather than relying solely on qualitative disclosures.

A structured climate risk assessment framework integrates risk identification with financial modeling and strategic planning, strengthening long term resilience while enabling organizations to align climate risk management with broader sustainability, disclosure, and decarbonization objectives.

Physical Climate Risk Assessment: Identifying Asset Level Exposure

Physical climate risk assessment focuses on how acute and chronic climate events affect business operations, infrastructure, supply chains, workforce productivity, and long term asset value. Increasingly, organizations are expected to conduct location specific and asset level assessments to quantify financial exposure under different climate scenarios in alignment with frameworks such as TCFD, IFRS S2, and CSRD.

Physical climate risks are generally categorized into acute and chronic risks. Acute physical risks are event driven and arise from the increasing frequency and severity of extreme weather events, while chronic physical risks result from long term shifts in climatic patterns that gradually impact operational and financial resilience.

Acute physical risks include:

• Hurricanes

• Floods

• Wildfires

• Extreme storms

• Cyclones, heatwaves, and extreme precipitation events with increasing frequency and severity

Chronic physical risks include:

• Temperature rise

• Sea level increase

• Long term drought

• Water stress, changing rainfall patterns, biodiversity loss, and long term degradation of ecosystem stability

A robust physical risk assessment involves:

• Asset mapping across geographies

• Hazard exposure modeling

• Vulnerability assessment

• Financial impact quantification

• Scenario analysis using climate pathways and forward looking climate projections

• Evaluation of operational, financial, and supply chain sensitivity to climate hazards

Organizations operating in climate sensitive regions must integrate hazard modeling with capital expenditure planning, infrastructure resilience strategies, insurance assessments, and business continuity planning. Advanced climate risk methodologies increasingly combine geospatial analytics, catastrophe modeling, and climate adjusted financial risk metrics to assess exposure across facilities, logistics networks, and critical supply chain nodes.

Companies often align physical risk assessment with broader climate transition strategy initiatives to ensure long term operational sustainability, support climate related financial disclosures, and enable long term adaptation planning across enterprise operations and investment portfolios.

Transition Risk Assessment: Navigating Regulatory and Market Shifts 

Transition risks arise from the global shift toward low carbon and climate resilient economies. These risks emerge as governments, financial institutions, investors, and industries accelerate decarbonization efforts through evolving regulations, technological transformation, market realignment, and changing stakeholder expectations. Under IFRS S2, transition risks are categorized across policy, legal, technological, market, and reputational dimensions, all of which may have material financial implications for organizations.

These include:

• Carbon pricing regulations

• Mandatory disclosure requirements

• Renewable energy adoption

• Fossil fuel phase out policies

• Investor driven ESG screening

• Climate related litigation and liability exposure

• Market shifts driven by low carbon technologies and changing consumer preferences

• Supply chain decarbonization requirements and green procurement expectations

Regulatory frameworks such as IFRS Sustainability Disclosure Standards, CSRD and regional climate disclosure mandates are accelerating compliance requirements and increasing pressure on organizations to demonstrate climate resilience, emissions transparency, and credible transition planning. Businesses are increasingly expected to quantify how transition risks may impact cash flows, access to capital, operating costs, and long term enterprise value.

A strong climate risk assessment framework evaluates exposure to regulatory developments policy uncertainty, carbon pricing mechanisms, technology disruption, and market transition dynamics. It also assesses cost of compliance, stranded asset exposure, supply chain vulnerability, and the potential financial impact of decarbonization pathways under different climate scenarios. Advanced transition risk assessments increasingly integrate scenario analysis, internal carbon pricing, and climate adjusted financial modeling to support strategic decision making and capital allocation.

Organizations integrating regulatory alignment within their sustainability strategy consulting efforts are better positioned to enhance transparency and investor confidence.

Scenario Analysis within Climate Risk Assessment Framework

Climate scenario analysis stress tests business models under different climate pathways and how it may impact business models, financial performance, operational resilience, and long term enterprise value. Increasingly embedded within TCFD and IFRS S2 requirements, scenario analysis enables organizations to assess the resilience of their strategy under a range of plausible climate futures rather than relying solely on historical data and static risk assumptions.

Common scenarios include:

Physical risk scenarios:

• Representative Concentration Pathways (RCPs) such as RCP 2.6, RCP 4.5, and RCP 8.5 used to model different greenhouse gas concentration trajectories and associated physical climate impacts

• Shared Socioeconomic Pathways (SSPs) such as SSP1-1.9, SSP2-4.5, and SSP5-8.5 that combine socioeconomic development assumptions with climate outcomes to evaluate long term physical risk exposure

• High warming and “hot house world” scenarios assessing extreme heat, flooding, sea level rise, and chronic climate disruption 

Transition risk scenarios:

• Net Zero Emissions by 2050 (NZE) scenario

• Orderly and disorderly transition scenarios developed by the Network for Greening the Financial System (NGFS)

Scenario analysis evaluates:

• Revenue sensitivity

• Asset impairment risk

• Capital expenditure adjustments

• Financing cost implications

Advanced climate scenario analysis increasingly integrates climate science, macroeconomic forecasting, geospatial risk analytics, and climate adjusted financial modeling to assess how transition and physical risks may evolve across short, medium, and long term horizons. Organizations are also leveraging NGFS, IEA, and IPCC aligned scenarios to strengthen climate resilience assessments, stress test business strategies, and support investor grade climate disclosures.

Organizations applying structured climate scenario analysis methodologies strengthen resilience planning and strategic forecasting.

Integrating Climate Risk into Enterprise Risk Management 

Climate risk should not remain isolated within sustainability or ESG departments. Increasingly, regulators, investors, and global disclosure frameworks such as TCFD and IFRS S2 expect climate related risks and opportunities to be integrated into enterprise wide risk management, governance, financial planning, and strategic decision making processes. Climate risk is now viewed as a material financial risk with the potential to affect cash flows, access to capital, asset valuation, operational continuity, and long term business resilience.

Integration includes:

• Board level oversight

• Risk committee reporting

• Internal audit processes

• Financial planning alignment

• Integration into enterprise risk registers and control frameworks

• Climate linked capital allocation and investment decision making

• Performance monitoring through key risk indicators (KRIs) and climate related metrics

Embedding climate risk into governance frameworks ensures accountability and alignment with long term strategy. Leading organizations are increasingly integrating climate risk into existing ERM frameworks such as COSO ERM and ISO aligned risk management systems to ensure climate risks are assessed alongside operational, financial, regulatory, and reputational risks.

Under IFRS S2, organizations are expected to disclose how governance bodies oversee climate related risks, how management responsibilities are structured, and how climate considerations are integrated into risk management, strategic planning, remuneration structures, and major business decisions. This includes demonstrating how climate risks are identified, assessed, prioritized, monitored, escalated, and incorporated into internal control and audit processes.

Advisory support from Aranca enables organizations to develop structured climate governance mechanisms, integrate climate considerations into enterprise risk management frameworks, strengthen disclosure readiness, and embed climate related financial risk assessment across strategic, financial, and operational decision making.

Data, Metrics and Carbon Accounting in Risk Evaluation 

Accurate, auditable, and decision useful data collection is foundational to effective climate risk assessment and climate related financial disclosures. As organizations face increasing scrutiny from regulators, investors, lenders, and rating agencies, robust climate data management and carbon accounting capabilities are becoming critical for quantifying risk exposure, conducting scenario analysis, and supporting credible transition planning.

Key data requirements include:

• Scope 1 emissions

• Scope 2 emissions

• Scope 3 value chain emissions

• Energy consumption intensity

• Climate related capital expenditure and operating expenditure data

• Asset level exposure data for physical climate risk assessment

• Internal carbon pricing assumptions and decarbonization targets

Structured carbon accounting for companies enhances the accuracy of risk modeling, supports regulatory reporting compliance and enables organizations to align disclosures with frameworks such as IFRS S2, GHG Protocol, CSRD, and other requirements. Increasingly, organizations are expected to disclose not only emissions data, but also the methodologies, assumptions, boundaries, estimation techniques, and governance processes used in climate related reporting.

Data transparency also strengthens investor trust and supports access to sustainable finance instruments. Aranca supports organizations with enterprise-wide carbon accounting, emissions baseline assessments, Scope 1, 2, and 3 emissions quantification, supplier emissions analysis, climate data management, and regulatory reporting alignment.
