Travelers to some U.S. cities can now rent eco-friendly cars. EV Rental Cars opened its first site at the Los Angeles airport in December 1998 and has since expanded to several other California airports. The company recently struck a long-term deal with Budget Rent-a-Car and has plans to open sites this year in Atlanta, Dallas, Houston, Las Vegas, Phoenix, and Washington, D.C. Its fleets include natural gas, electric, and gas-electric hybrid cars made by Honda, Toyota, and others.
