Sustainable development directly aligns with local, regional, national, and global security. In the last decade, much progress has taken place in graduate sustainability education and research. However, undergraduate sustainability education programs have not shown the same levels of achievement. Metropolitan State University of Denver (MSU Denver) is one of the pioneer universities to have established its Sustainable Systems Engineering Program at the undergraduate level. Since 2016, the Program has been revised and improved upon. This article details the relationship between undergraduate sustainability education and national security, and explores the undergraduate sustainability education practices at MSU Denver as a model. The authors emphasize the development of program educational objectives (PEO), curriculum design, and assessment. The recently developed course, “Leadership in Sustainable Design,” is discussed, illustrating the university’s introduction of general sustainability concepts to interdisciplinary undergraduate students.
