Curricular innovation is at the center of the challenges many colleges and universities face as they seek to help students address more successfully than previous generations the complex, multi-faceted, systemic challenges of global climate change, population growth, loss of biodiversity, environmental justice, toxic wastes, and food insecurity. The key to meeting these challenges is to inspire faculty creativity, whether the goal is to broaden an environmental approach with the "triple bottom line" of sustainability (economic and social, as well as environmental dimensions), to create sustainability minors or majors, or to integrate sustainability issues across the curriculum. This article describes the Piedmont/Ponderosa model, a successful approach to curricular change that has inspired faculty at dozens of colleges and universities around the country to integrate sustainability issues across the curriculum.
