In the heart of New York City just steps from Central Park, Columbia offers 24 environmental degrees, as well as a sustainable development major and a sustainability master's program. A $25,000 Green Fund offers support to student-led projects that focus on improving sustainability throughout the campus. The school has an award-winning laboratory waste solvent recycling program as well as annual reuse events that allow items to be collected to be recycled, re-used or disposed of in an environmentally friendly way. Pilots groups are working to develop innovative solutions for paper reduction throughout campus. Ten campus buildings are LEED-certified. Sustainability continues through graduation as all undergraduate and masters graduates wear "green gowns," each made from 23 recycled plastic bottles.
