# Managing Climate Scenario Analysis

## When To Use

- Conducting TCFD-aligned climate scenario analysis for portfolio or enterprise risk reporting
- Modeling transition risk exposure under different decarbonization pathways (e.g., Net Zero 2050, Delayed Transition, Current Policies)
- Assessing physical climate risk (acute and chronic) across asset locations or supply chains
- Preparing climate disclosures for annual reports, investor presentations, or regulatory filings
- Stress-testing capital allocation or lending portfolios against climate scenarios

## Inputs To Gather

- **Scenario framework selection**: NGFS scenarios, IEA World Energy Outlook pathways, or custom internal scenarios — confirm which reference pathways apply
- **Asset/portfolio data**: Sector exposures, geographic concentrations, revenue mix by business line, and Scope 1/2/3 emissions profiles where available
- **Time horizons**: Short-term (2025–2030), medium-term (2030–2040), long-term (2040–2050+) — confirm which horizons the analysis must cover
- **Risk taxonomy**: Distinguish transition risks (policy/legal, technology, market, reputation) from physical risks (acute events, chronic shifts)
- **Baseline assumptions**: Carbon price trajectories, energy mix forecasts, temperature alignment targets, and discount rates [VERIFY against latest NGFS or IEA vintage used]
- **Materiality thresholds**: What magnitude of financial impact triggers escalation or disclosure
- **Regulatory context**: Applicable disclosure regime — TCFD, ISSB/IFRS S2, EU CSRD/ESRS E1, SEC climate rule [VERIFY current status and applicability by jurisdiction]

## Workflow

1. **Define scope and governance**
   - Confirm reporting entity boundaries (consolidated, subsidiary, fund-level)
   - Identify scenario owners, data providers, and sign-off authority
   - Align on at least two contrasting scenarios (e.g., orderly transition vs. hot-house world) plus a baseline

2. **Map risk channels to financial drivers**
   - For each transition risk type, identify the transmission mechanism: carbon cost pass-through, stranded asset write-downs, demand destruction, litigation exposure
   - For each physical risk type, map to financial impact: asset damage/impairment, business interruption, insurance cost escalation, supply chain disruption
   - Tag each channel with affected financial line items (revenue, COGS, capex, asset values, provisions)

3. **Parameterize scenarios**
   - Assign quantitative assumptions per scenario: carbon prices ($/tCO2e by decade), energy prices, technology adoption curves, temperature pathways
   - Source chronic physical parameters from climate models (e.g., RCP 4.5 vs. RCP 8.5 for precipitation, sea-level rise, heat stress)
   - Document all assumption sources and vintages — flag any that are more than 18 months old as [VERIFY]

4. **Run financial impact analysis**
   - Calculate transition risk impacts: carbon cost burden as % of EBITDA, revenue at risk from demand shifts, capex required for technology transition
   - Calculate physical risk impacts: expected annual loss from acute events, chronic productivity or yield reductions, adaptation cost estimates
   - Aggregate to portfolio or entity level; express results as earnings-at-risk, NAV impact, or credit quality migration under each scenario

5. **Assess strategic resilience**
   - Evaluate whether current strategy is robust across scenarios or dependent on a single pathway
   - Identify concentration risks: sectors, geographies, or counterparties with outsized scenario sensitivity
   - Propose adaptation or mitigation levers: hedging, divestment, engagement, capital reallocation, insurance

6. **Compile management report**
   - Structure output per TCFD recommended disclosure pillars: Governance, Strategy, Risk Management, Metrics & Targets
   - Present scenario comparison tables with key financial metrics side-by-side
   - Include heat maps or summary visuals for geographic/sectoral risk concentration
   - State all material assumptions, data gaps, and model limitations explicitly

## Output

A management report containing:

- **Executive summary**: Key findings, most material risk channels, and strategic implications in 1–2 pages
- **Scenario descriptions**: Narrative and quantitative parameters for each scenario analyzed
- **Transition risk assessment**: Financial impact estimates by risk type and business segment
- **Physical risk assessment**: Asset-level or portfolio-level exposure analysis with geographic detail
- **Resilience evaluation**: Strategy robustness across scenarios, with identified vulnerabilities
- **Action items**: Prioritized recommendations for risk mitigation, further analysis, or disclosure enhancement
- **Appendices**: Assumption tables, data sources, methodology notes, and sensitivity analysis

## Quality Checks

- At least two contrasting scenarios are analyzed (not just a single pathway)
- Transition and physical risks are both addressed — omission of either category must be justified
- All carbon price, temperature, and energy mix assumptions cite a named source and vintage year
- Financial impacts are expressed in concrete metrics (dollar amounts, percentages, rating notch equivalents) rather than qualitative labels alone
- Time horizons cover at least one period beyond 2030 to capture long-tail climate dynamics
- Geographic specificity is adequate for physical risk — global averages are insufficient for asset-level exposure
- Disclosure alignment is confirmed against the applicable framework [VERIFY: TCFD, ISSB S2, ESRS E1, or SEC rule as relevant]
- Limitations section explicitly states what the analysis does not cover (e.g., second-order macroeconomic effects, litigation risk quantification)
- All unverified or estimated data points are marked [VERIFY]
