Science Magazine, the leading scientific journal, just featured an article on using chemicals in college laboratories that do not hurt humans. Energy generation, transportation, and purchasing were mentioned. Good models of campus transportation exist at Cornell and the University of Colorado. Their Transportation Demand Programs cost the colleges a quarter of a million a year, and they involve such things as free rides on buses, discounted parking fees for carpoolers, and reserved parking spots for carpoolers. By not charging people at Middlebury for parking, you are subsidizing parking.
User fees are a very good way to change behavior.
Students at the University of Colorado actually voted to have a fee imposed on them. The college needs to create incentives for people to carpool and should consider purchasing alternative fueled vehicles. Regarding energy generation, universities have a hard time in keeping up with growth demands. Try to reduce the demand or switch to renewable energy sources. Regarding purchasing, Middlebury College has no policies, and staff are within a certain culture and have no downtime for research.
