Yale's Office of Sustainability develops and implements sustainability practices at Yale. Yale is committed to reduce its greenhouse gas emissions 10% below 1990 levels by the year 2020. As part of this commitment, the university allocates renewable energy credits to offset some of the energy used by residential colleges. Eleven campus buildings are candidates for LEED design and certification. Yale Sustainable Food Project initiated the introduction of local, organic vegetables, fruits, and beef to all residential college dining halls. Yale was listed as a Campus Sustainability Leader on the Sustainable Endowments Institute’s College Sustainability Report Card 2008, and received a "B+" grade overall.
