Translate travel emissions into an internal carbon cost or an estimated offset budget. Combine a trip footprint with a carbon price, annual price escalation, timing, and the share of emissions you plan to price.
The main result is a nominal future carbon cost. It can represent an internal carbon charge or a rough offset budget, depending on the price entered.
This is not a quote for carbon credits, airfare, or regulatory compliance. Taxes, brokerage fees, credit quality premiums, and discounting are excluded.
A 2.4 t CO₂e trip priced at $35/t, escalating 5% for two years, produces a future price of $38.59/t and a total carbon cost of $92.61.
Yes. Enter the shadow price or internal fee your organization uses per metric ton of CO₂e.
The current price is compounded by the annual escalation rate for the number of years entered.
Yes, down to -100%, although a negative rate represents an assumed decline and should be documented.
No. It calculates only the carbon cost associated with the emissions and price assumptions.
Use the emissions priced field to apply the carbon price to less than 100% of the footprint.
