Education for sustainable development, the educational offshoot of the concept of ‘sustainable development’, has rapidly become the predominant educational response to the global environmental crisis. The authors apply a critical lens to the field and find it wanting in many regards. Sustainability Frontiers is an international, academic non-governmental organization based in Canada and the United Kingdom. It engages in research and innovation in the broad fields of sustainability and global education challenging dominant assumptions and current orthodoxies as it seeks to foster learner empowerment and action. It places particular emphasis on climate change, disaster risk reduction and peacebuilding and their implications for the nature and directions of sustainability education.
