This work contributes to education for sustainability with innovative pedagogy and a new conceptual approach. It is based on a realistic assessment of our future in the Anthropocene, based on principles of human security and scientific models of remaining safe operating space. It critiques current approaches to education for sustainability and highlights solutions. A chapter on the ethics of sustainability education provides the conceptual basis for a taxonomy of learning outcomes and a section on how culturally diverse communities of learners can transform their guiding values in today's classrooms. Special attention is given to cultural learning, developing shared visions and diverse approaches, collective learning from transition events such as the 2020 pandemic, cultures learning from each other, and teacher education. The book integrates environmental ethics, zero growth and climate mitigation into a blueprint to educate successfully for a Great Transition to a truly sustainable future for a smaller, wiser humanity.
