Brandeis University's Campus Sustainability Initiative seeks to reduce the University's environmental and climate change impact. The University's accomplishments in the arena of sustainability include the creation of a student-organized on-campus Farmers' Market, the implementation of a single-stream recycling program, and the transition to GreenE certified wind power for 15% of the school's electricity needs. Brandeis also offers an environmental studies academic program, which includes courses such as Greening the Ivory Tower: Improving Sustainability of Brandeis and Community, which serves as an incubator for student led sustainability projects. Student projects have included greening campus offices, running after-school environmental education programs for children in the Waltham schools, and cleaning up local streams and ponds. In addition, a student-led project in 2014 established a rooftop farm atop the Gerstenzang science building consisting of 1,500 potted milk crates.
