Are you thinking what we’re thinking? Yep: It’s time for a green college roundup! Maine’s College of the Atlantic has made good on its pledge to be a carbon-neutral campus, say school officials. “As far as we know, [COA is] the first in the world to make the commitment, and as far as we know, the first to do it,” says David Hales, president of the 300-student college, which offers one major: human ecology. Meanwhile, Oregon’s Portland State University plans to hire as many as 10 professors with expertise in sustainability to teach subjects from economics to biology to art. Michigan’s Walsh College has green-built an extension to its campus, and Northern Kentucky University has launched a campus-wide campaign to reduce fossil fuels. We give ’em all a gold star.
