At University of Alaska Fairbanks, in the dead of winter, a person may end up burning more fuel just getting their car warmed up, than it takes to commute to and back, or around campus. I used to live off campus and had my own car, and I never even took it there because I'd have to keep it running nearly 15 minutes just so it would be warm enough for a 3 minute drive. To try to minimize environmental impact, the university maintains a fleet of shuttles on campus which follow a scheduled loop around all the major areas of campus to prevent on campus vehicle shuttling. Another fleet can be called in advance for pick-up and drop off to and from any of the off campus facilities (There are 9-10 other major University facilities not on the actual campus). They've also recently teamed up with the Borough Transit System to provide free citywide bus transport on the BTS so all a student/employee has to do is flash their School ID card and they can ride any of the BTS buses for free.
