Stress-test the transition exposure of a household under a user-defined future carbon price. The calculation combines estimated emissions, planned reductions, cost pass-through, and an available budget or margin to show retained carbon cost and its financial impact without pretending to forecast policy.
The percentage shows how much of the selected annual budget or margin would be consumed by retained carbon cost in the stress scenario.
Transition risk also includes technology, demand, regulation, reputation, and supply-chain effects. This tool isolates carbon-price exposure only.
Ten t CO₂e at $120/t, after a 25% reduction and 50% pass-through, leaves $450 of retained cost. Against a $10,000 budget or margin, the impact is 4.5%.
Use activity data from the same reporting period and emission factors that match the activity, geography, and unit.
It reports carbon dioxide equivalent, so other greenhouse gases may be included when the emission factors already express their combined climate impact as CO2e.
Results can differ because system boundaries, emission factors, allocation methods, and the age of source data may not match.
Use it for planning and screening. A full transition-risk assessment requires broader operational and market analysis. Formal disclosures may require documented factors, organizational boundaries, and independent review.
Update it when activity levels, suppliers, energy sources, travel patterns, emission factors, or carbon prices change materially.
| Lever | Effect |
|---|---|
| Emission reduction | Lowers tons exposed before pricing |
| Cost pass-through | Reduces the share retained |
| Budget or margin | Sets the denominator for impact |
