Estimate carbon credits needed for freight emissions after operational reductions and supplier-backed insetting. Set a coverage target and procurement buffer to turn the remaining footprint into a credit quantity.
The main result is the number of one-tonne credits to procure for the selected share of net residual freight emissions.
Count insetting only when it is quantified under a compatible boundary and is not double counted. This tool does not assess credit or claim integrity.
For 800 t CO₂e, an 18% operational reduction leaves 656 t. Subtracting 40 t of eligible insetting leaves 616 t; full coverage plus a 3% buffer requires 634.48 credits.
Eligible insetting is subtracted after the operational reduction and cannot reduce residual emissions below zero.
Yes. Set the offset coverage percentage to the share your program intends to cover.
Coverage defines the claim boundary, while the buffer adds extra volume for uncertainty or procurement policy.
Net residual emissions are floored at zero, so the calculator will not produce negative credit requirements.
No. Project quality, registry status, additionality, permanence, and claims require separate review.
