POTSDAM -- Clarkson University has again been named one of the country's best institutions for undergraduate education and one of the nation's most environmentally friendly colleges, according to The Princeton Review.

The company features Clarkson in the new 2011 edition of its guidebook, "The Best 373 Colleges." Only about 15 percent of America's 2,500 four-year colleges and two Canadian colleges are profiled in the book.

Clarkson has also been named one of the best colleges in the Northeast by Princeton Review, which identified some of the colleges and universities that they feel "stand out within a region." "We're pleased to recommend Clarkson University to readers of our book and users of our site as one of the best schools to earn their undergrad degree," said the Review.

In addition, Clarkson received a high rating of 88 in Princeton Review's third annual green ratings of colleges, a measure of how environmentally friendly the institutions are, on a scale of 60 to 99.

The criteria for the rating cover three broad areas: 1. Whether students have a campus quality of life that is both healthy and sustainable; 2. How well a school is preparing students not only for employment in the clean energy economy of the 21st century, but also for citizenship in a world now defined by environmental challenges; and 3. How environmentally responsible a school's policies are.

Clarkson is consistently among the schools ranked well in both The Princeton Review and U.S. News & World Report's annual issue of "Best Colleges," where Clarkson is listed as a tier one national university. U.S. News also ranks the Clarkson School of Business Supply Chain Management Program ranked 14th in the nation and its engineering program among the top 100 nationwide.
