The theme of this monograph is sustainability, which is defined as development that meets the needs of present generations without compromising the ability of future generations to meet their own needs. Sustainability, which is rooted in environmentalism, has been broadened to embrace an array of economic development policies, projects, and behaviors. Following a definition of sustainability in the context of higher education, the discussion focuses on: (1) how and why institutions become involved in sustainability issues; (2) sources of resistance to sustainability movements, including fear of high costs, failure of proponents to present a unified vision, and rivalries among national political groups; (3) the role of trustees in exploring issues of sustainability, including reallocating resources, exploring socially conscious investing, protecting institutional impartiality and academic freedom, encouraging thoughtful dialog, and promoting outreach. Sidebars throughout the document offer case studies of sustainability programs; a list of questions for trustees and governing boards; an essay on the "greening" of the sustainability movement; a "gazetteer" of 10 campus sustainability efforts; the text of the "Talloires Declaration," a document committing to sustainable practices signed by officers of 270 higher education institutes; and a postscript titled "Sustainability on Campus" by Daniel J. Levin. (Contains 11 references and 4 web sites.) (RAB)
