With "greening" projects dotting the landscape of higher education across the nation, it is encouraging to witness the commitment of many colleges and universities to helping secure the future environmental viability of the nation. The challenges that come with this commitment, however, are not insignificant. A comprehensive university-wide sustainability program requires hard and dedicated work from all segments of the institution, as well as an expansive vision that involves developing effective partnerships with government agencies and like-minded institutions. St. John's University, one of the largest Catholic universities in the country, has embarked upon a broad sustainability program that engages all members of the university community in the implementation of energy-saving strategies in new and existing facilities, in the classroom, and in the living/learning environment. This article features St. John's Sustainability Initiative (SJSI) which has involved partnerships with local, state, and national government sustainability programs, as well as linkages with other environmentally sensitive universities in the New York metropolitan area. The SJSI provides a campus-wide framework for a variety of sustainability activities affecting all facilities operations. That framework guides the efforts of faculty, students, and administrators who are actively committed to environmental safety projects on all of the university's campuses.
