Sustainability professionals need specialized leadership competencies to effectively influence the complex, uncertain, conflicted, and dynamic (i.e., wicked) sustainability challenges of our time. Higher education programs can teach these leadership competencies and thus help professionals gain more influence and career success. This article has three objectives: 1.) define and justify leadership competencies that sustainability professionals need to address wicked challenges, 2.) describe a pedagogy to teach these competencies to professionals, and 3.) evaluate whether intended learning outcomes were achieved in applications of this pedagogy.
