This further addition to the International Environmental Law and Policy Series examines to what extent international law meets the needs of international action required in the field of environmental protection. Some of the world's leading practitioners and academics contribute significantly in identifying problems which have so far been inadequately dealt with, assessing the protection afforded by present general international law regarding Air Pollution, Water Pollution, Hazardous Waste, and Climate Change and the Ozone Layer, and in addressing the causes in regulatory deficiencies. There is a critical appraisal of the adequacy and efficiency of existing law and present procedures. The book presents the revised and edited papers presented at the Symposium held in Vienna in October 1990, under the auspices of the Austrian Institute for International Affairs.
