CO2e emissions per passenger kilometre on the network

In accordance with Article L 1431-3 of the Transport Code, Île-de-France Mobilités, SNCF Transilien and RATP provide travellers with information on greenhouse gas (GHG) emissions emitted during their journeys. This information is based on indicators updated annually and in accordance with the regulations in force (Decree No. 2017-639). Information on greenhouse gases is available in particular at the following sites: > ‘HTTPS://ME-DEPLACER.ILEDEFRANCE-MOBILITES.FR/ITINERAIRE’[ >](https://me-deplacer.iledefrance-mobilites.fr/itineraire)‘’[’ >](https://www.ratp.fr/itineraires)‘s’> The greenhouse gas emissions of a trip shall be calculated as follows: Emissions (in gCO2e) = distance travelled to make the journey x average amount of CO2e emitted by a passenger travelling one kilometre in the mode of transport in question. Where the route takes more than one mode of transport, the greenhouse gas emission corresponds to the sum of the emissions of journeys travelled in the different modes. **Emission factors used for calculation** The emission factors used are those of the ADEME Carbon Base, according to the values in force at the date of update of the indicators. More information on the website: [www.bilans-ges.ademe.fr](s) For the calculations carried out in 2020 (base year 2019), the emission factors are presented below. They include combustion emissions (direct) and upstream (indirect) emissions for each mode of transport: Electricity (for transport use) | 38.6 gCO2e per kWh —|— Non-road diesel (train) | 3.17 kgCO2e per litre Road diesel (bus) | 3.16 kgCO2e per litre BioGNV | 0,5559 kgCO2e per m³ Car (average power and motorisation) | 0.177 kgCO2e per traveler-kilometre **Calculation of GHG indicators for different modes of transport** The indicators are calculated below for the year 2019. For modes operated by different transport operators, an average emission factor shall be calculated from the average emissions of each network, weighted by its passenger-kilometres. This is the case for RERs and trains as well as buses.
