Empowering Teachers through Environmental and Sustainability Education draws inspiration from an empirical study exploring early career teachers’ attempts at enacting Environmental and Sustainability Education (ESE) in their everyday teaching practices. It showcases how a confluence of personal, professional and environmental identities supports implementation of ESE. Additionally, this book discusses key concepts and issues surrounding ESE and the ways in which teachers may claim agency and power to create change in their classroom practices. Drawing from theoretical perspectives, such as Bourdieu’s ‘thinking tools’ habitus and capital, theories of identity, and Foucault’s concept of power and knowledge relations, this book explores how teachers negotiate policies, curriculum, and institutional norms to further theoretical and practical understanding of ESE. The use of personal narratives offers new insights into teachers’ agency in creating localised yet powerful change through small and meaningful actions. The purpose of this book, therefore, is to explore ways in which meaningful change can be made in educational settings through these small agentive and yet empowering steps. This book reveals that teachers can enact agency and navigate the power structures that exist within educational settings in order to make ESE meaningfulwithin theirclassrooms.
