A Theory of Intergenerational Justice

This highly accessible book provides an extensive and comprehensive overview of current research and theory about why and how we should protect future generations. It exposes how and why the interests of people today and those of future generations are often in conflict and what can be done. It rebuts critical concepts such as Parfits' non-identity paradox and Beckerman's denial of any possibility of intergenerational justice. The core of the book is the lucid application of a veil of ignorance to derive principles of intergenerational justice which show that our duties to posterity are stronger than is often supposed. Tremmel's approach demands that each generation both consider and improve the well-being of future generations. To measure the well-being of future generations Tremmel employs the Human Development Index rather than the metrics of utilitarian subjective happiness. The book thus answers in detailed, concrete terms the two most important questions of every theory of intergenerational justice: what to sustain? and how much to sustain? Ultimately this book provides a theory of intergenerational justice that is both intellectually robust and practical with wide applicability to law, policy, economics, climate change and all other contexts that affect future generations.

Joerg Chet Tremmel is Fellow at the London School of Economics and Political Science. He is the Editor-in-chief of the Intergenerational justice Review and a visiting lecturer at the Joann-Wolfgang-Goethe-University Frankfurt, the University of Stuttgart and the Heinrich-Heine-University in Dusseldorf, Germany.
