Start with the business mechanism
A climate scenario is not a forecast. It is a structured set of assumptions used to test how an organisation could perform under different combinations of policy, technology, market and physical conditions. The analysis should begin with the organisation’s exposures, not with a generic global narrative.
For a financial institution, pathways may include borrower cash-flow deterioration, collateral damage, sector concentration, higher cooling and diesel cost, service disruption or demand for new green products. For an industrial company, pathways may include input cost, water stress, asset damage, regulation, technology substitution and customer preference.
- Climate driver
- Exposed asset, portfolio or activity
- Risk or opportunity mechanism
- Time horizon and scenario assumption
- Management response
- Financial consequence
Build a risk–scenario assessment
The same risk can behave differently under an orderly transition, disorderly transition and high-physical-risk scenario. Assessment should capture exposure, likelihood, impact, time horizon, residual risk and resilience under each scenario.
Scores support prioritisation but should not replace analysis. A medium score with a potentially severe long-term balance-sheet effect may still require strategic action, especially where decisions today create asset lock-in.
- Use explicit short-, medium- and long-term horizons
- Record scenario source, variables and assumptions
- Separate inherent exposure from management mitigation
- Identify weak or critical resilience conclusions
Translate climate into finance
Financial effects are often missed because climate specialists describe hazards while finance teams wait for a precise number. A joint working process should identify the pathway first, then determine the most supportable measurement basis.
Current effects are those already reflected in financial performance, position or cash flows. Anticipated effects arise from identified risks and opportunities expected to influence future planning or financial outcomes. The analysis may use point estimates, ranges, sensitivity analysis or qualitative explanation, depending on available evidence.
- Revenue and customer demand
- Operating cost and insurance
- Capital expenditure and asset useful lives
- Impairment, expected credit loss and provisions
- Liquidity, financing and cost of capital
Use the output for resilience and action
The value of scenario analysis lies in the decisions it changes: facility adaptation, lending appetite, portfolio limits, product innovation, energy investment, supplier strategy, capital allocation or contingency planning.
A resilience conclusion should therefore explain which elements of strategy remain viable, where vulnerability is concentrated, which actions are planned, how they are funded and what indicators management will monitor.
