Carbon dioxide emissions from passenger transport
A wide range of transport options exists, but choosing the one with lowest emissions is not always straightforward. One way to measure your environmental impact is to look at the CO2 emissions per passenger kilometre travelled.
Note: CO2 emissions are calculated using an estimate of the amount of CO2 per passenger-kilometre. Different modes of transport are considered, with an average number of passengers per mode used for estimates. As the number of passengers in a vehicle increases, the total CO2 emissions of that vehicle increases, but the emissions per passenger are fewer. The inland ship emission factor is estimated to be 245 g CO2/km, but data availability is still not comparable with that of other modes.
