As sustainability challenges increase in both frequency and magnitude, there is a growing need for leaders who can deal with such complexity. Education for Sustainable Development (ESD) develops knowledge,skills, and attitudes to enable the development of such leaders. This thesis focuses on the elusive “attitude” piece, more widely referred to as the affective domain. The research team interviewed experts on affective learning in either higher education or ESD contexts. Additionally, staff members from the case study organisation, Teach for Austria (TFA) were interviewed to determine how affective learning can be further developed within their fellow program. The five-level model (5LM) was employed to frame the findings of each interview set to provide recommendations for TFA. A feature of the Framework for Strategic Sustainable Development, the 5LM provides a strategic planning approach that allows for easier adaptation and implementation of the findings for other programs that wish to learn from this research. Therefore, this thesis serves to provide recommendations for developing affective learning in sustainability leadership programs. Making affective learning explicit and empowering one to reflect their own affective domain and their perspective on the world can have a positive impact on their life, as well as on their environment.
