Book excerpt: Sustainable development, as defined by the World Commission on Environment and Development, is "development that meets the needs of the present without compromising the ability of future generations to meet their own needs." More specifically, sustainable development is a process of change that seeks to improve the collective quality of life by focusing on economically, socially, and environmentally sound projects that are viable in the long-term. Sustainable development requires structural economic change and the foundation of that change is investment. In developing nations with low levels of domestic savings, investment predictably comes from abroad in the form of foreign direct investment. A large and ever expanding number of international investment agreements are in place to govern these transactions. While these accords seek to foster development while mitigating the risk involved in these types investments, many questions remain unresolved. This highly insightful book reflects the contributions of a variety of world renowned experts each of which is designed to provide the reader with valuable perspective on recent developments in investment law negotiations and jurisprudence from a sustainable development law perspective. It offers answers to pertinent questions concerning advancements in investment law, including the negotiation of numerous regional and bilateral agreements as well as the increasing number of disputes resolved in the World Bank's International Centre for the Settlement of Investment Disputes (ICSID), from different developed and developing country perspectives. It lays out future directions for new treaty negotiations and dispute settlement proceedings, as well as ongoing investment promotion efforts, against a background of rapidly evolving international relationships between economic, environment and development law. It focuses on key issues in investment laws which have emerged as priorities in the negotiation of bilateral and regional investment agreements, and have been clarified through recent decisions of the ICSID and other arbitral panel awards.
