Climate risk assessment is becoming essential for investment decisions. Understanding how climate change affects portfolios helps Canadian investors make informed decisions and prepare for an uncertain future.
Types of Climate Risk
Physical Risks
Direct impacts from climate change:
Acute Risks
- Extreme weather events (hurricanes, floods, wildfires)
- More frequent and severe
Chronic Risks
- Rising sea levels
- Increasing temperatures
- Water scarcity
- Prolonged droughts
Transition Risks
Risks from moving to a low-carbon economy:
Policy and Legal
- Carbon taxes
- Emission regulations
- Stranded assets
- Litigation risk
Technology
- Disruption by clean energy
- Obsolescence of carbon-intensive processes
Market
- Changing consumer preferences
- Investor divestment
- Reputation effects
Reputation
- Public perception
- ESG rating changes
Assessing Physical Risks
Real Estate

- Water rights considerations
Assessing Transition Risks
Portfolio Analysis Tools
TCFD Framework
Task Force on Climate-related Financial Disclosures recommends:
- Governance: Climate risk oversight
- Strategy: Business impact assessment
- Risk Management: Identification and management
- Metrics and Targets: Progress tracking
Carbon Footprint Analysis
- Measure portfolio's carbon intensity
- Compare to benchmarks
- Identify high-emitters
Stranded Asset Risk
- Fossil fuel reserves that may become uneconomic
- High-cost producers most vulnerable
Climate Scenarios
Scenario Planning
Investors should consider multiple scenarios:
Orderly Transition
- Carbon pricing rises steadily
- Technology develops rapidly
- Costs of inaction are high
- Earlier investments in green tech benefit
Disorderly Transition
- Sudden policy changes
- Higher long-term costs
- Market volatility
- Uneven industry impacts
Failed Transition
- Climate impacts severe
- Minimal policy action
- Infrastructure damage
- Investment returns affected
Canadian Considerations
Regional Variations
British Columbia
- Wildfire and flood risk
- Coastal property exposure
- Pacific trade implications
Prairies
- Drought and agriculture impacts
- Extreme temperature swings
- Water rights issues
Ontario and Quebec
- Urban infrastructure aging
- Manufacturing transition challenges
- Hydro power reliability
Atlantic Canada

Investment Implications
Adjusting Asset Allocation
Consider reducing exposure to:
- High-carbon sectors
- Real estate in high-risk areas
- Companies with weak transition plans
Consider increasing:
- Green infrastructure
- Climate tech solutions
- Companies with strong ESG practices
Engagement vs Divestment
Engagement
Work with companies to improve practices rather than selling shares.
Divestment
Remove high-carbon investments entirely.
Many Canadian institutions use both strategies.

FAQ
How do I assess my portfolio's climate risk?
Many financial institutions and ESG rating providers offer portfolio climate risk analysis. Look for tools that measure carbon footprint, scenario analysis, and physical risk assessment.
Does climate risk affect bond investments?
Yes. Companies with high climate risk may face credit rating downgrades, affecting bond values. Municipal bonds in coastal areas face physical risks.
Should I move all investments to green funds?
This depends on your risk tolerance, time horizon, and values. Complete divestment may increase concentration risk. Gradual rebalancing is often more practical.
