Data model

The table shows the CO2 equivalent emission factors for the various lines and modes of transport in the Paris region. These emission factors are expressed in passenger-kilometer (CO2 equivalent emitted by one passenger traveling 1 km). They are supplied by transport operators for public transport, and by Ademe's Base Carbone for the others.

The column CO2e/voy/km by transport mode aggregates the CO2e emission factors at the "transport mode" level. It is these values by mode that are used for the CO2 calculation of the route calculator Île de France Mobilités.
