Intergenerational Equity: Environmental and Cultural Concerns tackles intergenerational equity from various perspectives with a view to understanding what is fair and/or just within and among generations.

The full effects of decisions made today about many environmental policies -including climate change and nuclear waste- will not be felt for many years. For issues with long-term ramifications, analysts often employ discount rates to compare present and future costs and benefits. This is reasonable, and discounting has become a procedure that raises few objections. But are the methods appropriate for measuring costs and benefits for decisions that will have impacts 20 to 30 years from now the right ones to employ for a future that lies 200 to 300 years in the future? This landmark book argues that methods reasonable for measuring gains and losses for a generation into the future may not be appropriate when applied to a longer span of time. Paul Portney and John Weyant have assembled some of the world's foremost economists to reconsider the purpose, ethical implications, and application of discounting in light of recent research and current policy concerns. These experts note reasons why conventional calculations involved in discounting are undermined when considering costs and benefits in the distant future, including uncertainty about the values and preferences of future generations, and uncertainties about available technologies. Rather than simply disassemble current methodologies, the contributors examine innovations that will make discounting a more compelling tool for policy choices that influence the distant future. They discuss the combination of a high shout-term with a low long-term diescount rate, explore discounting according to more than one set of anticipated preferences for the future, and outline alternatives involving simultaneous consideration of valuation, discounting and political acceptability.

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?

This book challenges mainstream Western IEJ (intergenerational environmental justice) in a manner that privileges indigenous philosophies and highlights the value these philosophies have for solving global environmental problems. Divided into three parts, the book begins by examining the framing of Western liberal environmental, intergenerational and indigenous justice theory and reviews decolonial theory. Using contemporary case studies drawn from the courts, film, biography and protests actions, the second part explores contemporary Māori and Aboriginal experiences of values-conflict in encounters with politics and law. It demonstrates the deep ontological rifts between the philosophies that inform Māori and Aboriginal intergenerational justice (IJ) and those of the West that underpin the politics and law of these two settler states. Existing Western IEJ theories, across distributional, communitarian, human rights based and the capabilities approach to IJ, are tested against obligations and duties of specific Māori and Aboriginal iwi and clans. Finally, in the third part, it explores the ways we relate to time and across generations to create regenerative IJ. Challenging the previous understanding of the conceptualization of time, it posits that it is in how we relate—human to human, human to nonhuman, nonhuman to human—that robust conceptualization of IEJ emerges. This volume presents an imagining of IEJ which accounts for indigenous norms on indigenous terms and explores how this might be applied in national and international responses to climate change and environmental degradation. Demonstrating how assumptions in mainstream justice theory continue to colonise indigenous people and render indigenous knowledge invisible, this book will be of great interest to students and scholars of environmental and intergenerational philosophy, political theory, indigenous studies and decolonial studies, and environmental humanities more broadly.

In this book Professor Weiss combines thorough research and careful analysis with imaginative solutions and a moral fervour, to show how rules of international law can be applied in an intertemporal dimension, and how the basic principles of the intergenerational equity can be developed to provide new standards for human behaviour. She manages to communicate to the reader not only that the situation is getting desperate but also that human intelligence can in time devise adequate remedies, without destroying completely our way of life.

In Intergenerational Equity: Environmental and Cultural Concerns, the editors have produced an important, broad-based volume on intergenerational equity. The authors explore the principle of intergenerational equity in many dimensions, from the theoretical to the practical. While the primary focus is on intergenerational equity in the context of environmental resources and cultural heritage, the principle is also addressed in a broad array of other contexts. The final section of the volume considers intergenerational justice as it applies to indigenous peoples, genocide, migration, sovereign wealth funds and foreign investment. The chapters also provide a critical analysis of the issues and a consideration of the difficulties in implementing intergenerational equity.

This volume, a collection of seven essays by individuals prominent in the water resources field, commemorates the tenth anniversary of the Water Science and Technology Board. The essays cover a variety of current issues in the field, including intergenerational fairness and water resources, the relationship between policy and science for American rivers, changing values and perceptions in the hydrologic sciences, challenges to water resources decision making, and changing concepts of systems management. An overview of institutions in the field is also given.
