Enter shipment weight, distance, and mode
Add the shipment weight in tonnes, the distance in kilometers, and select road, rail, sea, or air as the primary transportation mode.

How it works
We apply a mode-specific emission factor
Each mode has a genuinely different average CO2e-per-tonne-km factor — the tool multiplies your tonne-km by that factor to estimate total emissions.
Get an estimated CO2e figure and efficiency score
The result shows estimated kg and tonnes of CO2e, how it compares to an equivalent road shipment, and a relative carbon-efficiency score.

Frequently asked questions
Are these emissions figures measured or estimated?
Estimated. ShipmentCarbon applies standard, publicly known industry-average emission factors per mode — it does not measure actual fuel burn, vehicle efficiency, or route-specific conditions for your shipment.
Where do the emission factors come from?
They reflect commonly cited industry-average ranges for CO2e per tonne-kilometer by mode (similar in spirit to frameworks like GLEC or DEFRA conversion factors), simplified into one representative figure per mode for estimation purposes.
Why does air freight show such a higher estimate than sea?
Air freight has a substantially higher CO2e-per-tonne-km factor than sea or rail due to fuel intensity per unit of cargo moved — this is a well-documented and consistent pattern across industry emissions data.
Can I use this for a multi-leg shipment with different modes?
Run the calculator once per leg using that leg's weight, distance, and mode, then add the resulting CO2e figures together for a total estimate.
Is this suitable for official carbon reporting?
No — for compliance-grade reporting, use a certified carbon-accounting methodology and your actual carrier or fuel data. This tool is for quick directional comparison between shipment options.
