How to use this calculator
- Enter annual emissions linked to heat-risk operations.
- Use your organization’s internal or scenario carbon price.
- Add the planned reduction percentage and planning horizon.
- Calculate current exposure and avoided cost.

Heat Risk Carbon Cost Calculator
Convert heat-related operational emissions into an internal carbon cost, compare the current footprint with a reduction scenario, and quantify avoided carbon liability.
Calculator
Enter your assumptionsFormula
Annual carbon cost = emissions × internal carbon price. Horizon savings = emissions × reduction rate × price × years.
What the result means
The main result is the carbon-cost exposure accumulated over the selected horizon if emissions and price remain constant.
This is an internal planning estimate, not a tax forecast. Enter the carbon price used by your own organization.
Example calculation
For 850 tCO₂e at $75 per tonne, annual exposure is $63,750. Over five years it is $318,750; a 20% reduction avoids $63,750.
Tips for better results
- Use the same emissions boundary as your investment proposal.
- Test more than one carbon-price scenario.
- Keep physical energy savings separate from carbon-value savings.
- Update emissions after resilience equipment or cooling systems change.
Frequently asked questions
Is internal carbon cost the same as a carbon tax?
No. An internal price is a planning assumption; an actual tax or allowance cost is jurisdiction-specific.
Should the carbon price include inflation?
This calculator holds price constant, so use an average scenario price if escalation matters.
What emissions belong in a heat-risk carbon cost estimate?
Include only emissions within the boundary of the heat-risk activity or program being evaluated.
How is avoided carbon cost calculated?
It multiplies the reduced tonnes by carbon price and the selected number of years.
Can this calculator value energy savings too?
No. Add utility savings separately to avoid mixing physical cost reductions with carbon valuation.
