The system would start out with 2,000 cars in the city, and 2,000 additional cars in cities surrounding Paris.
"The green scheme, dubbed Autolib (short for "automobile" and "liberté"), is scheduled for launch as early as the end of 2010, although city officials say the startup date could be closer to mid-2011. Advocates say the system would reduce carbon dioxide emissions by 22,000 tons a year while improving traffic congestion as fewer Paris residents would need to own cars. It would be the first major city to offer such a service. "This could revolutionize transport," Delanoë told French radio station RMC when he first proposed the program in June 2008."
