The ambition of most countries across the world is to develop a low-carbon economy, evidenced by the fact that the vast majority of countries have signed the Paris COP21 agreement. This book contends that this global societal transition to a low-carbon economy must be just. As such, it will be an invaluable and accessible reference for scholars from all research disciplines who aim in their research to see a fairer, more equitable and inclusive world where sustainability is at the fore and climate targets are achieved. This is the first in-depth and original analysis to explore the central importance of law in achieving a just transition to a low-carbon economy. In addition, it advances the JUST framework, a unique framework for assessing the just transition. This important research and theoretical tool provides a practical perspective as it ensures the geographical space and timelines of development are factored into analysis. The research also provides analysis on the just transition movement around the world and the influence of international institutions. Through several case studies on Just Transition Commissions and Critical Mineral Development, the book details and demonstrates key elements of justice, including distributive, procedural, restorative, recognition, and cosmopolitan justice. It is clear from the analysis that while these are vast areas for analysis, if applied in practice, they all centrally contribute to ensuring society will advance in achieving a just transition to a low-carbon economy.
