Car-sharing can be seen as an effective measure for reducing the burden of automobile traffic on the environment. The automobiles belonging to Swedish car-sharing organizations are often newer and have more satisfactory environmental and safety characteristics than Swedish cars in general. Studies have also shown that a member of an average car-sharing scheme drives only about two-thirds as much as earlier and that a shared car, through being used more effectively, takes the place of some five privately owned cars and as many parking spaces. Car-sharing also represents an important complement to other types of environmentally friendly forms of traffic.
