In 1999, Italy launched pilot projects for car sharing in the Italian cities of Palermo and Venice. According to the ENEA, other Italian cities began experimenting with the service in 2000 - including Milan, Rome, Genoa, Bologna, Turin, and Naples. Under this model, cars are made available in public locations to subscribers in a service similar to but cheaper than a rental car. A contribution to the environment will come from the fact that cars used in the car-sharing programme will pollute less than other vehicles on the road. Venice and Palermo are both using electric autos in their fleet.
