A network of volunteers, the International Union for Conservation of Nature Commission on Education and Communication (CEC), present some reflections on their contributions towards the field of education for sustainability from 1992 to the present. Many CEC members have been thought leaders to this multidimensional field, and advocates for a more strategic approach that engages key stakeholders in action. Through the Decade of Education for Sustainable Development, the CEC continues to reflect on how to leverage change more effectively in dialogue with young professionals and those from diverse disciplines. Finally, in looking forward, some thoughts for this still emerging field are advanced.
