has long been a major focus of the university's Board of Regents and Presidents. In February 2006, the UW joined a partnership with Seattle City Light as part of their Green Up Program, ensuring that all of Seattle campus' electricity is supplied by and purchased from renewable sources. In 2010, then UW President Emmert furthered the university's efforts with a host of other universities across the U.S., and signed the American College & University Presidents' Climate Commitment. UW created a Climate Action Team, as well as an Environmental Stewardship Advisory Committee (ESAC) which keeps track of UW's greenhouse gas emissions and carbon footprint. Policies were enacted with environmental stewardship in mind, and institutional support was provided to assist with campus sustainability. Additionally, UW's Student Housing and Food Services (HFS) office has dedicated several million dollars annually towards locally produced, organic, and natural foods. HFS also ceased the use of foam food containers on-campus, and instead opted for compostable cups, plates, utensils, and packaging whenever possible. New residence halls planned for 2020 are also expected to meet silver or gold LEED standards.
