From the Sierra Club: "This year's winning school offers almost 600 sustainability-related classes taught by some of the greenest minds anywhere—more than 40% of UConn's research faculty does original academic work that benefits the environment. Since 2005, the main campus, in Storrs, has slashed its water use by 15%—and over the past two years, 13 of its buildings were retrofitted to prevent 2,640 tons of carbon dioxide emissions annually. In the trayless dining halls, 30% of meal options are vegetarian, and more than a quarter of the food is processed within 100 miles, with many ingredients harvested right on campus: Honey comes from UConn's apiaries, fresh eggs from the agriculture department, and seasonal produce from student-run gardens."
