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 Route Planners CO2 calculationÎle de France Mobilités.
