For the fifth consecutive year, Arizona State University made The Princeton Review's "Green Honor Roll," a list that includes universities across the nation that promote sustainability in education, practices, and partnerships. ASU has the largest collection of solar panels of any public university and numerous LEED-certified buildings. Sustainability is a core goal across departmental curriculum. The university is also pursuing carbon neutrality by 2035. As part of the recognition, ASU will appear in The Princeton Review's Guide to 322 Green Colleges: 2013 Edition, the only free publication that offers information on the top colleges focusing on sustainability.
