Estimate the carbon cost embedded in a freight program using annual shipment emissions, a price per metric ton, and optional free or exempt emissions. Compare current cost with a future carbon-price scenario.
The main result is annual freight carbon cost at the future price. The supporting results isolate the chargeable volume and show the increase from the current-price case.
Regulatory coverage, allowances, taxes, currency, and pass-through terms vary. Enter values that match the contract or policy being analyzed.
With 950 t CO₂e and 100 exempt tonnes, 850 tonnes are chargeable. At $85/t, future cost is $72,250, which is $46,750 above the $25,500 current-price case.
They represent emissions not charged in your scenario, such as an allowance allocation or a policy exemption.
Yes, but chargeable emissions are floored at zero and no negative carbon cost is created.
No. It includes only the chargeable emissions multiplied by the carbon price.
Yes. Use the current and future fields for any two per-tonne carbon prices that share the same currency.
No. If only part of the carbon cost is passed through, adjust the price or analyze the pass-through separately.
