LetsGo is one of first and largest car-sharing schemes based in Denmark. Our goals are less noise, polution and congestion in cities, and the tool to reach this goal are more sharing cars and more green mobility. 4,700 members in Copenhagen, Odense, Aarhus and Roskilde share a total of 300 cars, and we are experiencing a growing interest from both private individuals and companies. Studies show that a shared car with a permanently reserved parking space replaces at least 7 ordinary cars.
