Apply an internal carbon price to Scope 1, Scope 2, and selected Scope 3 emissions while preserving the underlying footprint totals. The calculator shows gross emissions, priced emissions, and the internal carbon charge available for budgeting or investment screening.
Priced emissions = Scope 1 + Scope 2 + (Scope 3 × Priced share). Internal charge = Priced emissions × Internal carbon price.
The main result is the internal carbon charge created by the entered price and coverage. Gross emissions remain a physical inventory measure; the charge is a management value, not an emissions reduction.
An internal carbon price may be a shadow price, internal fee, or implicit price. This calculator does not determine external tax liability or accounting treatment.
Scope 1 of 2,400 t plus Scope 2 of 1,800 t and 50% of 6,200 t Scope 3 equals 7,300 priced tonnes. At $65/t, the internal charge is $474,500.
Organizations often phase in categories or apply an internal price only where data and decision influence are sufficient.
No. It assigns a monetary value to emissions; reductions occur only when activities or emission factors change.
Use the Scope 2 basis adopted by the inventory and decision process, and label it consistently.
No. It is an organizational decision tool unless a separate external law creates an actual liability.
The charge can be included in scenario cash flows to compare options with different emissions profiles.
| Variable | Meaning | Unit |
|---|---|---|
| Gross footprint | Scope 1 + Scope 2 + included Scope 3 | t CO₂e |
| Priced Scope 3 | Scope 3 multiplied by coverage | t CO₂e |
| Priced emissions | Footprint receiving the internal price | t CO₂e |
| Internal charge | Priced emissions multiplied by price | USD |
