Sharing lifts to school and work has always been a favoured transport method, with ride sharers helping reduce the amount of CO2 omissions released into the atmosphere. This is also a great marketing focus for cab-sharing applications, claiming to be offering an environmental service as well as a transport one. Carpooling in the term used, with Uber’s UberPool attempting to match riders travelling in the same direction. As well as doing their bit for the planet ride sharers also save money on their cab fair, splitting the balance between the people they are travelling with. Uber stated that UberPool could save up to 102 tonnes of CO2 each and every month, arriving at this sum by comparing cab sharing to the traditional one-passenger cab fair. ‘Conservatively assuming that every UberX vehicle is a Toyota Prius — thus getting its gas mileage of 50 mpg — UberPool trips saved around 13,500 gasoline gallons. Accounting for a savings of 8.91kg of atmospheric CO2 emissions per gallon, San Francisco’s UberPool efforts prevented about 120 metric tons of CO2 emissions from Feb to 20 Mar, equivalent to the output of over 128,000 pounds of coal.’ Maaxi in Britain Where UberPool and Lyft Line are not available in the UK taxi app Maaxi has introduced can sharing to Britain.
