While some colleges have signed the President’s Climate Commitment, dedicated resources to hire staff and put specific metrics and goals in place to assess institutional progress, most colleges have not placed such a prominent role on sustainability. Yet most colleges view sustainability positively, whether for financial, mission, curricular, or other reasons. This paper focuses on the role that grass-roots leadership can play in achieving sustainability gains at a resource-constrained mission-driven campus. Specifically, we present the story of a small college that has made significant advances in sustainability working within existing budgets and utilizing existing faculty and staff. Using a highly collaborative leadership process, people from many different departments across campus have been able to work together to simultaneously promote sustainability while accomplishing core job requirements. While the campus has limited financial resources to dedicate to sustainability, soft resources like the creation of a Green Team and the signing of the St. Francis Pledge provided ways to integrate sustainability efforts across the campus. Key themes include a collaborative approach in conjunction with a campus climate that empowered individual employees and promoted community goals.
