In 2008, the University of Illinois at Urbana-Champaign (the University or Illinois) signed the American College & University Presidents' Climate Commitment. This action committed the campus to carbon neutrality by the year 2050. The Illinois Climate Action Plan (iCAP), signed in 2010, describes a path toward the fulfillment of this commitment. As the flagship public university in the state of Illinois, the campus has a moral and ethical responsibility to lead, to set aggressive goals, to work to meet them, and to serve as a model for the community, state, and nation. The Plan represents a roadmap to a new, prosperous, and sustainable future for the University. It outlines strategies, initiatives, and targets toward meeting the stated goal of carbon neutrality by 2050. The campus Strategic Plan from 2007 envisions an Illinois Sustainable Energy and the Environment Initiative that focuses on power generation and networks, transportation and portable energy, water supply and use, and landscapes and urban architecture. It envisions a learning laboratory for demonstration of sustainable technologies and curricula to prepare students with skills required to tackle the challenges of a sustainable society.  The Strategic Opportunity in Global Sustainability Challenges: A Vision for the University of Illinois at Urbana-Champaign document proposes a vision of the future for the campus in addressing two long-term global societal sustainability challenges: (1) To maintain or restore natural ecosystem function while providing essential human services; and (2) To sustainably raise the quality of life for the world’s poor to acceptable levels. The Climate Action Plan is the refinement of the first challenge into tangible actions and activities that lead directly to greenhouse gas (GHG) reductions.
