Responsibility not to cause transboundary environmental harm

This article explores the content of the responsibility of a state not to cause transboundary (environmental) harm to other states and areas beyond the limits of national jurisdiction. It will consider whether the admissibility of an activity may be affected as a result of the hazardous nature of an activity, the environ¬mental impact of an activity in the normal course of its operation, or the magnitude of the risk of adverse environmental effects associated with an activity. In addition to the admissibility of activities, the tolerable levels of harm and the (due diligence) nature of the responsibility will be addressed.
