The Sustainable Endowment Institute has released its second College Sustainability Report Card, grading the environmentaliciousness of the 200 U.S. colleges with the largest endowments. Two-thirds of the schools received better grades this time around; the average overall grade was a C+, with six schools receiving an overall A- for their efforts. The colleges were graded on transportation, administration, climate and energy, food and recycling, green building, and investment priorities, as well as endowment transparency and shareholder engagement (both of which most schools solidly failed). Among the encouraging statistics: Around half of the schools have committed to reducing greenhouse-gas emissions, more than two-thirds have green building policies, and more than 80 percent source at least some cafeteria food locally.
