To integrate the principles, values, and practices of sustainable development into all aspects of education and learning was the overarching goal of the UN Decade of Education for Sustainable Development (2005-2014). This, it was believed, would 'save the planet', encouraging behaviour changes to allow for the development of a more sustainable and just society for all. Awareness of sustainable development has risen enormously in recent years, challenging us, as individuals and as families, workplaces, and communities (both local and global), to think about and act upon the major issue which we face. The Decade reaffirmed the United Nations' commitment to the crucial role of education and learning in the pursuit of sustainable development, and the need for far-reaching changes in the way education is often practised. Of course, the very idea that education should be for something (whether sustainable development or anything else), remains as questionable as ever. Nevertheless the instigation of the Decade clearly recognised the need for intensified efforts to achieve sustainable development. This book reflects on the role and impact of the Decade in helping to reorient education towards sustainability, and looks forward, beyond the end of the Decade and its achievements, to contemplate the way ahead, giving special attention to case studies and the state of affairs in England. The authors offer different perspectives on the effectiveness and value of particular initiatives and practices that are responses to the Decade. This book was originally published as a special issue of The Curriculum Journal.
