A key area of public policy in the 20 years from 1979 is the question of how, and how much, to protect the environment. At the heart of this has been the heated debate over the nature of the relationship between economic growth and environmental sustainability. Is environmentally sustainable economic growth or "green growth", a contradiction in terms? Avoiding the confusion that often surrounds these issues, Ekins provides expositions of the concept of sustainability, integrated environmental and economic accounting, the Environmental Kuznets Curve, the economics of climate change and environmental taxation. Individual chapters are organized as self-contained expositions of the core issues of environmental economics, with extensive cross-referencing from one chapter to another, in order to guide the student or policy-maker through these complex problems. Paul Ekins defines the conditions of compatibility between economic growth and environmental sustainability, and provides measures and criteria by which the environmental sustainability of economic growth, as it occurs in the real world, may be judged. It is argued that "green growth" is not only theoretically possible but economically achievable and the authors show what environmental and economic policies are required to achieve this.
