Colby has electric and hybrid vehicles and is committed to improving fuel economy and emissions in the College-owned fleet. A campus shuttle provides access to local shopping areas and public transportation, and an online ride-sharing board facilitates carpooling. Students and employees can join Zipcar, a low-cost car-sharing program. Beginning in 2008 students initiated the iBike program to offer free bike loans to students and staff. The motivation was to provide sustainable transportation and equitable access to downtown Waterville as well as an opportunity for healthy exercise. Bikes come with a helmet and lock and may be checked out at the information desk in Cotter Union for up to 24 hours at a time.
