This book analyses key aspects of transboundary environmental law and policy and their implementation in Asia, Australasia and areas beyond national jurisdiction including Antarctica. It discusses the potential for implementing key transboundary environmental mechanisms, such as the 1991 Convention on Environmental Impact Assessment in a Transboundary Context (Espoo Convention) and its 2003 Protocol on Strategic Environmental Assessment (Kiev Protocol) in Australia and Asia, drawing on experience from other regions and the potential application of these agreements to all UN member states.
