Physical climate risks represent the direct impacts of climate change on operations, assets, and supply chains. Under ASRS, organisations must assess both acute and chronic physical risks and disclose their exposure and management strategies.
Understanding physical climate risk is essential for business continuity, asset protection, and investor disclosure requirements.
What are Physical Climate Risks?
Physical climate risks arise from the direct effects of climate change, including changes in weather patterns, increased frequency and severity of extreme events, and long-term shifts in climate conditions. Unlike transition risks, which stem from the societal response to climate change, physical risks are the actual climate impacts themselves.
Physical Risk Categories
ASRS and TCFD classify physical risks into two categories:
Acute Physical Risks
Event-driven risks from extreme weather:
- Cyclones and hurricanes: Wind damage, flooding, storm surge
- Floods: Riverine, flash, and coastal flooding
- Bushfires: Direct damage, smoke, evacuation
- Heatwaves: Equipment failure, worker safety, demand spikes
- Hail and storms: Property damage, business interruption
- Drought: Water scarcity, agricultural impacts
Chronic Physical Risks
Long-term shifts in climate patterns:
- Sea level rise: Coastal erosion, inundation, saltwater intrusion
- Rising temperatures: Cooling costs, heat stress, productivity
- Changing precipitation: Water availability, flood frequency
- Ocean acidification: Marine ecosystem impacts
- Permafrost thaw: Infrastructure damage in cold regions
- Agricultural shifts: Growing season changes, crop suitability
Climate Hazards by Region
Australia faces distinct climate hazards requiring regional assessment:
- Northern Australia: Cyclones, flooding, sea level rise
- Eastern Seaboard: Floods, bushfires, heatwaves
- Southern Australia: Bushfires, drought, heatwaves
- Western Australia: Heatwaves, drought, bushfires
- Central Australia: Extreme heat, drought
- Coastal zones: Sea level rise, storm surge, erosion
Physical Risk Assessment Methodology
A comprehensive physical risk assessment involves:
- Hazard identification: Identify relevant climate hazards by location
- Exposure analysis: Map assets and operations to hazard zones
- Vulnerability assessment: Evaluate susceptibility to identified hazards
- Financial impact quantification: Estimate costs of damage and disruption
- Risk scoring: Prioritise risks by likelihood and consequence
Exposure Mapping
Organisations should map exposure across:
- Direct operations: Facilities, equipment, infrastructure
- Supply chain: Key suppliers, transportation routes, ports
- Markets: Customer locations, demand patterns
- Workforce: Employee locations, commute routes
- Finance: Collateral, insurance, investment portfolios
Vulnerability Assessment
Vulnerability depends on:
- Asset characteristics: Age, construction, design standards
- Adaptive capacity: Ability to respond and recover
- Interdependencies: Reliance on infrastructure and services
- Insurance coverage: Financial protection and gaps
- Business continuity: Backup systems and contingency plans
Financial Impact Quantification
Quantify potential financial impacts:
- Direct damage: Asset repair and replacement costs
- Business interruption: Revenue loss during recovery
- Supply chain disruption: Production delays, alternative sourcing
- Increased costs: Higher insurance, cooling, water
- Asset devaluation: Reduced value of exposed properties
- Stranded assets: Uninsurable or uninhabitable locations
Climate Scenario Analysis
Physical risk assessment should incorporate climate scenarios:
- Current climate baseline: Present-day hazard frequency and severity
- NZE 2050 scenario: Limited warming, best-case physical risk outlook
- Above 2°C scenario: Moderate warming, increased physical risk
- Current policies (3-4°C): High warming, severe physical risk
Use CSIRO climate projections and IPCC reports for scenario parameters.
Physical Risk Disclosure Requirements
ASRS requires specific physical risk disclosures:
- Material physical risks: Acute and chronic risks identified
- Financial impacts: Quantified or described effects
- Time horizons: Short, medium, and long-term exposure
- Scenario analysis: Resilience under different warming levels
- Adaptation measures: Actions taken to manage risks
- Governance: Board oversight of physical risks
Adaptation Strategies
Effective adaptation responses include:
- Infrastructure resilience: Hardening, elevation, relocation
- Nature-based solutions: Wetlands, green infrastructure
- Operational changes: Flexibility, redundancy, diversification
- Insurance: Coverage review, parametric insurance
- Supply chain resilience: Alternative suppliers, inventory buffers
- Monitoring: Early warning systems, climate intelligence
Physical Risk Tools and Data
Organisations can access multiple data sources:
- CSIRO Climate Change in Australia: Regional climate projections
- Bureau of Meteorology: Historical weather data, alerts
- Geoscience Australia: Hazard mapping, exposure data
- IPCC Reports: Global climate science synthesis
- Commercial providers: Climate risk analytics platforms
