Abstract Despite efforts to realize Agenda 2030, the sustainable development goals (SDGs) may not be achieved. This already now impacts public health and healthcare, including the training of providers. “Sustainable health” addresses this urgency by emphasizing health as key to achieving the SDGs. While the UN developed a competency framework for teachers in 2011, the specific competencies needed to train in sustainable health remain unclear. Transformative learning (TL) is crucial to integrating sustainable development in higher education (HE), yet its application in the education of health professionals is limited. TL entails a profound transformative journey that reshapes perceptions and experiences, necessitating a shift in the educator’s role from information provider to facilitator of transformative processes. According to a 2019 literature review on TL for healthcare students, teachers need detailed and practical guidelines on how to implement TL. We aimed to develop an evidence-based matrix outlining a) the educational strategies needed to ensure that students develop sustainable health competencies, and b) the competencies teachers need to use these strategies in a quality-assured way. We conducted a literature review to identify key dimensions of teacher competencies and educational strategies for sustainable health. We surveyed teachers at Karolinska Institutet to assess the relevance of these competencies and teachers’ confidence in using them. Focus group discussions were conducted, to explore barriers and enablers to develop competencies and use educational strategies. We present a competency framework for HE teachers, accompanied by recommended educational strategies and self-assessment tools to gauge further training needs. To be used by teachers and educational developers, it will be openly accessible in Swedish and English. This study contributes to enhancing competencies in training health professionals to contribute to achieving sustainable health for all. Key messages • Educators need to be equipped with competencies to lead transformative learning processes to enable future generations of health professionals to achieve sustainable health for all. • Educators need to be supported to transform their role and practice to provide relevant training for future health care providers.
