Estimate the CO2e of a trip leg. Choose the transport mode and distance, and the tool estimates kilograms of CO2e per person and in total, then compares the same distance across modes. Emission factors are rough averages, so figures are estimates only, not a carbon audit; all processing runs locally.

How to Use the Travel Carbon Footprint Estimator
Choose the transport mode, the distance and how many people travel, then press Estimate.
Reading the results
Per person is the estimated CO2e for one traveller.
Total is the estimated CO2e for the whole group; for a car it is split between travellers.
Comparison lists each mode for the same distance so you can see lower-carbon options.
