It's pretty much the greenest way you can drive. Based on a UC Berkeley study of City CarShare members conducted in 2006, collectively our members reduce CO₂ by 35+ million pounds per year. Each person who joins City CarShare saves nearly 100 gallons of gasoline each year, on average. When you add it all up over our lifetime, our members have driven 100 million fewer miles and saved over 130 million pounds of CO₂.

Plus, for every vehicle we put on the road, lots more come off. Some say it's 7, some say it's 20; all we know is it's making a real difference.

Put simply, every new membership—including yours—is very good news for the environment.
