UConn adopted an environmental policy in 2004 and includes sustainability in its master plan and strategic plan. A green purchasing policy mandates the purchase of energy-efficient electronics, recycled paper, and green cleaning products. The Office of Environmental Policy (OEP) employs two full-time and two half-time staff members. The Environmental Literacy Workgroup, a subcommittee of the 25-member Environmental Council, helped create EcoHouse, a new residential community.
