Climate risk assessment has become a fundamental requirement for Australian organisations preparing for mandatory disclosure under the Australian Sustainability Reporting Standards (ASRS). Understanding, quantifying, and disclosing climate-related risks enables informed decision-making by investors, regulators, and stakeholders.
Understanding Climate Risk
Climate risk encompasses the potential negative impacts of climate change on organisations, assets, and communities. The Task Force on Climate-related Financial Disclosures (TCFD) framework, now embedded in ASRS, categorises climate risks into two primary types:
Physical Risks
Physical risks arise from the direct impacts of climate change:
- Acute physical risks: Event-driven hazards including floods, bushfires, cyclones, storms, and heatwaves
- Chronic physical risks: Longer-term shifts in climate patterns including sea level rise, sustained temperature increases, changed precipitation patterns, and water scarcity
Australian organisations face significant physical risk exposure given the continent’s climate vulnerability. The 2019-2020 bushfires and 2022 floods demonstrated the material financial impacts of climate events on businesses, supply chains, and communities.
Transition Risks
Transition risks emerge from the shift to a lower-carbon economy:
- Policy and legal risks: Carbon pricing, emissions regulations, litigation exposure
- Technology risks: Disruption from renewable energy, electric vehicles, energy efficiency
- Market risks: Changing consumer preferences, shifting commodity prices, stranded assets
- Reputational risks: Stakeholder perception, investor activism, social licence to operate
Transition risks vary significantly by industry. Carbon-intensive sectors face greater exposure, though all organisations must assess their vulnerability to decarbonisation trends.
Climate Risk Assessment Process
A systematic climate risk assessment follows structured stages:
1. Establish Context
Define assessment boundaries and parameters:
- Organisational scope (operations, value chain, investments)
- Geographic coverage (Australian and international locations)
- Time horizons (short, medium, long-term aligned with strategic planning)
- Materiality threshold for risk prioritisation
- Governance and accountability for the assessment process
2. Risk Identification
Systematically identify climate-related risks:
- Physical risk screening: Asset-level exposure to climate hazards using climate projections and geographic data
- Transition risk analysis: Sector-specific exposure to policy, technology, market, and reputation risks
- Value chain mapping: Supply chain and distribution vulnerabilities
- Stakeholder engagement: Input from operations, finance, strategy, and external experts
3. Risk Analysis
Assess likelihood and consequence for identified risks:
- Likelihood: Probability of risk materialising under different climate scenarios
- Consequence: Financial, operational, and strategic impact magnitude
- Timeframe: When impacts are expected to materialise
- Existing controls: Current mitigation measures and their effectiveness
Risk analysis may be qualitative (high/medium/low ratings) or quantitative (financial modelling, scenario analysis).
4. Risk Evaluation
Prioritise risks for treatment:
- Apply materiality thresholds aligned with ASRS requirements
- Rank risks by residual risk rating
- Identify risks requiring immediate action versus monitoring
- Document rationale for prioritisation decisions
5. Risk Treatment
Develop targeted responses for material risks:
- Avoid: Divest from high-risk activities or locations
- Mitigate: Implement controls to reduce likelihood or consequence
- Transfer: Insurance, contractual arrangements, hedging
- Accept: Monitor risks within tolerance levels
Document treatment plans with clear accountability, timelines, and success metrics.
Climate Scenario Analysis
ASRS requires climate scenario analysis to assess organisational resilience. Scenario analysis explores how climate-related risks and opportunities may evolve under different plausible futures:
Recommended Scenarios
The ASRS standards reference scenarios aligned with global climate targets:
- 1.5°C scenario: Rapid decarbonisation consistent with Paris Agreement goals
- 2-3°C scenario: Moderate transition reflecting current policy trajectories
- 3-4°C scenario: High emissions pathway for physical risk assessment
Scenarios should illuminate different risk profiles—the 1.5°C scenario emphasises transition risks while higher-warming scenarios highlight physical risks.
Scenario Analysis Approaches
Organisations may apply different levels of sophistication:
- Qualitative analysis: Narrative descriptions of scenario impacts on strategy and operations
- Semi-quantitative: High-level financial estimation of scenario impacts
- Quantitative modelling: Detailed financial modelling of scenario pathways using climate data and economic assumptions
ASRS expects organisations to progressively enhance analytical sophistication over successive reporting periods.
Physical Risk Assessment Methods
Assessing physical climate risks requires understanding hazard exposure and vulnerability:
Hazard Identification
Map exposure to climate hazards using:
- Climate projection data (CSIRO, Bureau of Meteorology, IPCC)
- Hazard mapping tools (flood, bushfire, cyclone zones)
- Asset location data and geographic information systems
- Historical loss data and near-miss events
Vulnerability Assessment
Evaluate asset and operational sensitivity:
- Infrastructure design standards and climate resilience
- Supply chain dependencies and alternatives
- Workforce exposure to heat stress and extreme weather
- Business continuity arrangements
Financial Impact Quantification
Translate physical risks into financial terms:
- Asset damage and replacement costs
- Business interruption losses
- Insurance premium increases and coverage gaps
- Supply chain disruption costs
- Adaptation capital requirements
Transition Risk Assessment Methods
Transition risk analysis examines exposure to decarbonisation trends:
Policy Risk Analysis
Assess exposure to current and emerging policy:
- Carbon pricing mechanisms and potential expansion
- Emissions standards and regulatory requirements
- Renewable energy targets and mandates
- Climate litigation trends and precedents
Technology Risk Analysis
Evaluate disruption potential from low-carbon technologies:
- Renewable energy cost trajectories and grid integration
- Electric vehicle adoption rates and infrastructure
- Energy efficiency technologies
- Low-emissions production processes
- Disruptive business models enabled by technology change
Market Risk Analysis
Examine demand and pricing shifts:
- Consumer preferences for low-carbon products and services
- Investor expectations and access to capital
- Commodity price impacts (fossil fuels, critical minerals)
- Stranded asset risk for carbon-intensive investments
Integrating Climate Risk into Enterprise Risk Management
Climate risk should be embedded within existing risk management frameworks:
- Risk register integration: Add climate risks to corporate risk registers with consistent rating methodologies
- Risk appetite alignment: Define climate risk tolerance in risk appetite statements
- Board reporting: Provide regular climate risk updates to board and risk committees
- Control effectiveness: Monitor and report on climate risk mitigation measures
- Emerging risk surveillance: Scan for evolving climate risks and regulatory developments
Integration demonstrates mature climate governance and supports ASRS disclosure requirements.

Risk Management Disclosures
Explain how climate risks are managed:
- Processes for assessing and prioritising climate risks
