This tool helps you estimate the carbon emissions (tCO₂e) of transporting goods across road, sea, and air, using UK government greenhouse gas conversion factors (DENZ/DEFRA) to ensure consistency and credibility .It’s designed for awareness, planning, and can be used as part of a wider carbon audit or reporting process.
You can calculate emissions from multiple modes of transport in a single journey.
If two legs of the journey use the same type of vehicle or vessel, simply add the distances together and enter the combined figure into the relevant segment.
