An ongoing discussion in education for sustainable development (ESD) research has focused on defining a list of agreed upon sustainability competencies required for the work of sustainability change agents. This discussion has included the consideration of an ‘Intrapersonal’ perspective that considers the role of inner qualities in change agents and how this impacts their ability to implement sustainability. While many researchers have looked at the ‘inner dimension’ of sustainability work, the identification and function of an ‘Intrapersonal’ competence remains in question. Utilizing practitioner responses, this paper identifies eight Intrapersonal capacities that change agents described as beneficial to their implementation of sustainability. These capacities are the ability to: Hold complexity, Foster a learner’s mindset, Deeply value others, Let be, Show up as one’s full self, Regulate and manage the self, Persist with lightness and Ensure one’s wellbeing. The study provides insights into the identification of the capacities and their relationship to a wider Intrapersonal research field. It also discusses the implications this perspective has on education for sustainable development should it consider incorporating such capacities into teaching and learning. While much literature in the field is of conceptual nature, this paper offers an empirical contribution by including the voice and perspective of change agents to the Intrapersonal discussion.
