Goucher College and the University of Maryland College Park rank among the greenest institutions of higher learning in the nation on the latest College Sustainability Report Card, boosting their grades to A- on the annual rating of everything from campus food and recycling to green building and the handling of their endowments.

Greenest seven in the nation - with 'A' grades - were Brown University, Dickinson College in Carlisle PA, University of Minnesota, Oberlin College, Pomona College, University of Wisconsin - Madison, and Yale University.

Goucher and UMCP got top marks on the green-ness of virtually all aspects of campus life and operations, but got marked down, respectively, for their lack of endowment transparency and "shareholder engagement," the latter term referring to whether the school uses its stock ownership to take public stands at shareholder meetings on issues like climate change.

Johns Hopkins University, meanwhile, saw its grade slip to a C-plus this year, with just middling scores for food, recycling and green building and similarly poor assessments of its endowment operations.

Loyola University, the only other Maryland school rated, improved its grade this year to a C.
