This document provides an introduction to education for sustainable development. It discusses key concepts such as the definition of sustainable development from the Brundtland report and perspectives that question the concept. The challenges of education for sustainability are explored, including the need to equip students with sustainability literacy and for education to address unsustainability. Critical questions are raised about whether current education contributes to or helps solve sustainability problems. The goal of the UN Decade of Education for Sustainable Development is presented to integrate sustainable development values into all aspects of learning.
