The University of Notre Dame has made being a sustainability leader an integral part of its mission, creating the Office of Sustainability in 2008 to achieve a number of goals in the areas of power generation, design and construction, waste reduction, procurement, food services, transportation, and water.As of 2012[update] four building construction projects were pursuing LEED-Certified status and three were pursuing LEED Silver. Notre Dame's dining services sources 40% of its food locally and offers sustainably caught seafood as well as many organic, fair-trade, and vegan options. On the Sustainable Endowments Institute's College Sustainability Report Card 2010, University of Notre Dame received a "B" grade. The university also houses the Kroc Institute for International Peace Studies. Father Gustavo Gutierrez, the founder of Liberation Theology is a current faculty member.
