This book offers an innovative exploration of energy justice, from concept to action, highlighting its role as a crucial tool for navigating the complexities of a just and sustainable energy transition. The book is timely and as the global energy transition rapidly progresses, it will serve as an essential resource, offering practical guidance to advancing a just and sustainable energy future. The perspectives presented in this book are presented by early career energy justice scholars from around the world, each highlighting and proposing ways to navigate the transition. The discussion focuses on three key themes: the integration and repurposing of energy infrastructures with the use of technology, the need for affordable and accessible energy services, and the promotion of responsible governance through effective policymaking and corporate social responsibility. At the heart of this book is the presentation of the 'Toolkit to Achieve the Just Transition using the Energy Justice Framework'.
