Willamette University’s commitment to sustainability is characterized by the “Four E’s”: equity, environment, economics, and education. The university’s definition of sustainability extends beyond environmental issues to include social justice, demonstrated by the institution of a living wage standard for every one of its employees. In 2004, the Sustainability Council was formed to oversee sustainability initiatives. A green purchasing policy requires the use of paper products and carpets with recycled content and green cleaning products. President Pelton has signed the Presidents Climate Commitment.
