This book applies rigorous economic analysis to the question of sustainable development. It considers the inter-relationship between growth and sustainability showing that one does not necessarily exist to the detriment of the other. Sustainability may be measured and defined in national accounting terms and the contributors explore a potentially powerful theoretical definition. Case studies on Morocco and China examine some of the domestic policy requirements of sustainability, revealing the desirability of quite complex combinations of policies. International policy aspects of sustainability are considered, such as technology transfer and the establishment of workable agreements to reduce global pollution. The volume demonstrates the need to build the sustainability debate on sound economic foundations, and the ability of economists to provide such foundations.
