For road journeys, the distance is calculated by Google using best route road algorithms. For rail, these are calculated according to main rail line distances using the most common rail interchanges. For air travel, distances are calculated using data by Geonames.org.

The Travelfootprint calculator is part-funded by Transport for London and Camden Council.
