The study explored physical education teacher educators’ (PETE educators) perspectives on integrating sustainable development (SD) imperatives within PETE courses. Nine PETE educators participated in a nine-month professional learning project featuring six workshops and seminars promoting reflection, peer discussion and dialogic encounters. The PETE educators designed pedagogical interventions based on their teaching practices, selecting teaching units where SD perspectives could be integrated. Data included intervention papers, audio-recorded sessions and logbooks, analysed descriptively and thematically. The proposed interventions focused on inclusion, equality and lifelong physical activity, and typically included lectures, seminars, student-centred teaching, reflections and assignments. Challenges included contextualising SD in PETE, framing SD goals, integrating SD content and addressing its normative nature. The study offers insights into the potential of integrating SD perspectives in PETE, highlights associated challenges, and calls for further research to bridge theory and practice.
