Since 2006, the APPA (Association of Higher Education Facilities Officers) Thought Leaders Series has brought together experts in higher education for two days of discussion about the challenges facing colleges and universities in North America. Energy and the environment were the focal points for the 2009 Thought Leaders Symposium, and the result is this whitepaper, which considers the major challenges posed by environmental sustainability to higher education institutions. During the symposium, participants heard from experts on different aspects of energy use and environmental sustainability. They also broke into working groups to identify specific challenges to implementing sustainability and energy management strategies on campus. The economic situation was never forgotten--for each major issue, teams evaluated the implications of the global recession. In the end, the following major points were established--points that became the outline of Section II of this paper: (1) Environmental Sustainability; and (2) Energy Issues. Section III of this report shifts the focus to a discussion of the response of facilities leaders to higher education's challenges. Section IV focuses on the top critical issues confronting facilities leaders in 2010. Appendices include: (1) References and Resources; and (2) Participants in the 2009 Thought Leaders Symposium.
