Biodiesel buses newest additions to UNM shuttle fleet
Friday, June 6th, 2008
Four biodiesel buses are new additions to the shuttle fleet run by UNM Parking and Transportation Services. The Thomas Built ‘Safe‐T‐Liners’ have 30 or 48 seats and are in operation around campus.
“Biodiesel was an obvious choice” says Alexander A. Aller, manager, Public Transit Operations. “Right now, all of our large shuttles are alternatively fueled with either biodiesel or compressed natural gas. Although we have a small fleet, we are pleased to contribute to efforts that reduce carbon dioxide emissions, dependence on foreign oil, and the pace of global warming.”
What has been the reception given to the new vehicles as they hit the routes in and around campus?
“Generally, very favorable,” Aller said. “We could have continued maintaining our existing fleet, but older vehicles are far less reliable and more expensive to operate and maintain. Plus, the publicized overall environmental footprint associated with biodiesel is notably smaller than fossil fuel.”
The measure strengthens the university’s commitment to sustainability.
The plan is to keep these buses running for the next ten to 15 years to meet the changing needs of the University Community,” Aller said. “Operating safely, efficiently, and effectively with minimal energy usage is at the top of our agenda.”
