Car renters meet demand with new fleets of hybrids.
Roo Rogers, who lives in Lower Manhattan, helps reduce auto emissions by not owning a car. But he still likes to take the wheel for occasional multistop spins around town, for hundred-mile drives to a vacation home on Long Island and for business trips when he's in California. When he rents a car or uses a car-sharing service, Rogers tries to help the environment a little more by driving only a hybrid vehicle, the Toyota Prius. And he has ridden to the airport using OZOcar, a car service of which he was a founder; it has an all-hybrid fleet of Priuses and a few Lexuses.
