To use or not to use: shared mobility for emission-free cities

Cities anticipate a growing need for mobility. However, physical space in a city is limited. Cities are faced with the challenging task of keeping cities accessible and liveable (clean air), making the best possible use of limited public space and ensuring mobility is as emission-free as possible. Shared mobility seems a promising, though partial, solution as 1) emission-free driving leads to cleaner air in the city, 2) car sharers own cars less often and drive fewer kilometres, and 3) shared mobility leads to fewer cars on the street.
