How to use this calculator
- Enter emissions exposed to transition pricing.
- Set current and future carbon-price assumptions.
- Apply the reduction expected before the future scenario.
- Compare incremental exposure with operating profit.

Internal Carbon Price Transition Risk Calculator
Stress-test an emissions footprint against a higher future carbon price and measure the potential pressure on operating profit. The result is a transparent scenario exposure—not a forecast—designed to help compare decarbonization plans and financial resilience.
Calculator
Transition scenarioFormula
Future emissions = Current emissions × (1 − reduction %)
Incremental exposure = Future emissions × future price − Current emissions × current price
Incremental exposure = Future emissions × future price − Current emissions × current price
What the result means
The main result is incremental carbon-cost exposure between the current and future cases. A negative value means modeled reductions more than offset the price increase.
This simplified scenario excludes pass-through, free allowances, taxes, technology capex, and interactions with specific regulations.
Example calculation
40,000 tCO2e costs $2.0 million at $50. After a 25% cut, 30,000 tCO2e costs $3.6 million at $120, creating $1.6 million of incremental exposure.
Tips for better results
- Use several future prices.
- Separate direct and value-chain exposure.
- Link reductions to funded projects.
- Compare exposure with profit and cash flow.
- Update scenarios as policy changes.
Frequently asked questions
Why does this calculator use carbon-price scenarios?
Scenario prices show how exposed annual earnings could become if the effective cost of emissions rises.
Should I enter tonnes of CO2 or CO2e?
Use metric tonnes of carbon dioxide equivalent (tCO2e) consistently across all emissions fields.
What happens if I enter zero?
Zero is accepted where it is meaningful. The calculator blocks negative values and any input that would make the selected scenario invalid.
How should uncertain inputs be handled?
Run conservative, central, and optimistic cases by changing the uncertain inputs and compare the resulting exposure.
Can this result be used for regulatory reporting?
It is a planning estimate only. Apply the required reporting standard, boundaries, factors, and assurance process separately.
