Sustainability Fellowship Group

Back Row (L to R):  Oltan Akin, Joseph Roohan, Juan Dent, Gregory Miller, Rafael Go
Front Row (L to R): Jane Xie, Rachel Charow, Ellen Ebert, Serena Li, Veronica Motley.

In June 2013, ten Undergraduate Sustainability Fellows embarked on a year-long journey of sustainability in theory and practice. The program, sponsored by Georgetown University's Office of the Provost, Department of Culture Communications and Technology, Center for Social Justice, and the Office of Sustainability used the campus as a Living Lab to provide classroom and real-world learning opportunities while helping advance sustainability on campus.

The Fellows work in teams to collect data and implement sustainability projects on campus. Their projects include Donating Reusable Goods, Biking and Transportation, Green Spaces and Storm Water Management, Regents Hall Data Visualization, an empirical study on campus composting practices, and consulting for the SIPS Green Revolving Loan Fund. The data and deliverables produced by the students are directly informing Georgetown’s campus-wide sustainability efforts and plans.
