Estimate shipment emissions
Compare the indicative CO₂e footprint of your shipment across transport modes.
Estimated emissions
1.98 t CO₂e
10 g CO₂e per tonne-km, well-to-wake
Indicative planning estimate based on GLEC-style default factors. Actual emissions depend on route, load factor, equipment and fuel.
Same shipment, compared by mode (t CO₂e)
Overview
Understand transport emissions estimates
The emissions calculator gives logistics teams a quick, consistent estimate of a shipment's greenhouse gas emissions. Enter the transport mode, cargo weight and distance to see the result in tonnes of CO₂e, and compare the same shipment across ocean, rail, road and air.
Estimates use indicative well-to-wake emission factors per tonne-kilometre, informed by the GLEC Framework and ISO 14083. They are designed for planning — comparing modes, testing routing options and preparing supplier conversations — rather than for audited disclosure.
For reporting, our teams can provide shipment-level calculations using actual routing, vessel and fuel data where available. These replace default factors with operational data and document the boundary, method and assumptions used.

How we work
A practical, accountable approach
Our teams connect operational decisions with measurable priorities and clear communication.
02
Mode comparison
See how the same shipment compares by ocean, rail, road and air to inform modal decisions early in planning.
03
Well-to-wake
Factors include fuel production as well as combustion, giving a more complete picture than tailpipe emissions alone.
04
Recognised methods
Calculation logic follows GLEC Framework principles and the ISO 14083 standard for transport chain emissions.
05
Detailed reports
For disclosure, account teams prepare shipment-level calculations using actual routing and fuel data where available.
06
Reduction ideas
Results highlight where modal shift, consolidation or lower-carbon options could make the biggest difference.

How it works
How the emissions estimate is produced
The calculator follows a transparent activity-based sequence informed by the GLEC Framework and ISO 14083.
- 01
Define the movement
Capture origin, destination, transport mode, cargo weight and relevant shipment or service details. Confirm whether the requested estimate covers a single leg or a multi-leg logistics chain.
- 02
Establish the boundary
Identify included activities and lifecycle scope. For comparable logistics-chain reporting, apply consistent boundaries and disclose exclusions, allocation choices and any material data limitations.
- 03
Apply activity and factors
Calculate transport activity and apply appropriate mode-specific emissions factors. The GLEC Framework provides logistics emissions accounting guidance and is aligned with ISO 14083 requirements for quantifying and reporting transport-chain emissions.
- 04
Review and use responsibly
Check units, assumptions and available data quality, then interpret the result as an estimate. Retain supporting inputs and do not present indicative outputs as independently verified inventory figures.
