The number one source of greenhouse gas emissions at Cal Poly Pomona is from transportation activities, most significantly from daily student, faculty, and staff commuting. The university is committed to reducing the number of cars arriving at campus each day as well as reducing the number of vehicle miles traveled. Cal Poly Pomona is also committed to eliminating emissions associated with the campus fleet.

Since joining the Presidents’ Climate Commitment, Cal Poly Pomona has made the campus fleet more environmentally friendly. Facilities Planning & Management is reducing its dependence on gasoline. Facilities has converted nearly a third of its fleet of gasoline vehicles to electric cars and trucks. The number of electric vehicles now totals 29, which includes four-door sedans and pick-up trucks built by MILES Electric Vehicles. The vehicles plug into a standard electrical outlet and require four to six hours of charging. Although the work trucks are capped at 25 miles per hour, they're also powerful enough to drive uphill to Kellogg House carrying a 1,000-pound load. These vehicles, which are used for a variety of landscape and custodial tasks, are just one step toward reducing the campus's carbon emissions.

Diesel engines at Cal Poly Pomona are making a healthy switch to biodiesel. In April 2009, Facilities installed a 500-gallon biodiesel tank that will supply fuel for all landscape equipment, including tractors and mowers, and the diesel engine street sweeper. In addition, one of the Bronco Express shuttles will run on biodiesel.
