Abstract
All nations of the world have ratified the Post 2015 Agenda, Global Action Program (GAP) on ESD and the Incheon Declaration 2015. The GAP and Incheon have prioritized to build capacities of educators and trainers to enable them to deliver ESD. This study was conducted to explore the teacher educators’ (TEs) perceptions about the issues posing threats to sustainable development (SD) at the global and national levels, perceived role of teacher education in SD, the possible SD curricular spaces and the barriers in doing so. A questionnaire was distributed to 108 TEs of nine TEIs. They were found much below the satisfactory level on knowledge and understanding of the concepts and issues hindering sustainable development. They did not perceive much relevance of SD concepts in the courses they were teaching. They expressed that neither they have time and authority to modify the curricula nor do they have administrative and institutional support to do so.
