In order to reduce motorised traffic, people will have to adopt a less car-dependent lifestyle. To manage this shift in mentality and behaviour, cities need to promote new forms of transport use and ownership. Car sharing is one way to reduce motorized traffic and carbon emissions and make a valuable contribution to more sustainable urban mobility. This e-course provides an introduction into the concept of car sharing in a variety of forms as well as experiences of different cities that already have implemented a car sharing scheme.
