History
The Oregon State University Sustainability Office is housed within University Facilities, Infrastructure and Operations, part of the Finance and Administration division. The Sustainability Office was formed by the creation of a full time sustainability position in November 2005. In December 2007, an additional half-time position was created primarily to support the collection and management of campus utility data. In November 2008, the half-time position was moved to a permanent full time position and duties expanded to focus on energy conservation efforts.
