Enterprise Holdings Shifts to Biodiesel for Car Rental Airport Shuttles

Enterprise Holdings announced plans for its entire fleet of more than 600 Alamo Rent A Car, Enterprise Rent-A-Car and National Car Rental airport shuttle buses across more than 50 North American markets to begin using at least 5 percent biodiesel (B5). Further, the company will immediately convert buses in nine markets to 20 percent biodiesel (B20) as a first step toward the company’s goal of converting its entire bus fleet to B20 over the next five years.

Enterprise Holdings expects to complete the conversion to all B5 by spring of this year, with at least 50 percent converted to B20 by the end of next year. Buses in nine markets are immediately being converted to run on B20 where the fuel is centrally stored and available: Boston, Chicago, Denver, Detroit, Los Angeles, Miami, Raleigh/Durham, San Antonio and San Diego.

“This investment in biodiesel follows our commitment to our customers and our business to use our fleet to help grow the clean fuel market. By embracing alternative fuels and engine technologies, they have a greater opportunity to become commercially viable,” said Lee Broughton, director of corporate identity and sustainability for Enterprise Holdings. “Biodiesel’s benefits to the environment support our commitment to environmental stewardship, as well as our sustainable approach to managing our business for long-term success.”

The company announced its biodiesel conversion plans at the National Biodiesel Board (NBB) 2010 National Biodiesel Conference & Expo in Dallas. As noted by the NBB, the environmental improvements associated with the company’s switch to biodiesel for airport shuttles include:

  • A reduction in carbon emissions in the first year equivalent to retiring 40 buses from the company’s fleet;
  • Reducing the company’s petroleum use by approximately 420,000 gallons in the first year its buses run on biodiesel;
  • Reducing the emission of particulate matter, which has been shown to be a human health hazard; and
  • Reducing the emission of hydrocarbons, which contribute to the localized formation of smog.
