Since 2012, AASHE has collaborated with Sierra and The Princeton Review to allow colleges and universities in the U.S. and Canada to use the STARS Reporting Tool to share their sustainability data for potential inclusion in Sierra‘s Cool Schools ranking and The Princeton Review’s Guide to Green Colleges. 

Based on the positive response to the data sharing process in 2018 and 2019, we will be following the same process in 2020. The submission deadline for inclusion in both rankings, as well as AASHE’s annual Sustainable Campus Index (SCI), is March 6, 2020. Please review the Data Sharing Instructions carefully to make sure your institution is included.

If you have questions about the process of submitting and sharing a STARS report, please email
