Sustainability

In 2006, the university established the Office of Environmental Stewardship to initiate, coordinate and implement programs to reduce the university's environmental footprint. The U.S. Green Building Council selected the university's Manhattanville plan for the Leadership in Energy and Environmental Design (LEED) Neighborhood Design pilot program. The plan commits to incorporating smart growth, new urbanism and "green" building design principles. Columbia is one of the 2030 Challenge Partners, a group of nine universities in the city of New York that have pledged to reduce their greenhouse emissions by 30% within the next ten years. Columbia University adopts LEED standards for all new construction and major renovations. The university requires a minimum of Silver, but through its design and review process seeks to achieve higher levels. This is especially challenging for lab and research buildings with their intensive energy use; however, the university also uses lab design guidelines that seek to maximize energy efficiency while protecting the safety of researchers.

Every Thursday and Sunday of the month, Columbia hosts a greenmarket where local farmers can sell their produce to residents of the city. In addition, from April to November Hodgson's farm, a local New York gardening center, joins the market bringing a large selection of plants and blooming flowers. The market is one of the many operated at different points throughout the city by the non-profit group GrowNYC. Dining services at Columbia spends 36 percent of its food budget on local products, in addition to serving sustainably harvested seafood and fair trade coffee on campus. Columbia has been rated "B+" by the 2011 College Sustainability Report Card for its environmental and sustainability initiatives.

According to the A. W. Kuchler U.S. potential natural vegetation types, Columbia University would have a dominant vegetation type of Appalachian Oak (104) with a dominant vegetation form of Eastern Hardwood Forest (25).
