Risk has always been an element of life. Yet modern technology continues to spread environmentally hazardous activity beyond State boundaries. These hazardous—yet socially useful—activities exist in a grey area between legality and wrongfulness.The Environment, Risk and Liability in International Law explains the important role liability plays in risk management and environmental protection, within the realm of international law. The text explores questions such as the lawfulness of acts which negatively affect the environment, as well as who should be liable for transfrontier damages. From private to public interest, from individual to common concern, activities involving risk are a growing preoccupation of our societies.
