The Post Baccalaureate Diploma (PBD) in Sustainable Development is a post-undergraduate program. This program is for people who have recently finished a degree and want to bridge to a Sustainability-related career or those with professional experience in Sustainability who wish to obtain an academic credential. It is also an excellent fit for people who are making a major change of field. This PBD combines courses in Sustainable Development (SD) theory and guided practice, plus upper division electives from various disciplines, permitting students to shape the diploma to their own interests. The diploma focuses on the community or city scale, while making linkages to the global scale, and includes a required, student-designed practicum/project to address a particular problem in SD.
