"Gerry Nagtzaam contends that in recent decades neoliberal institutionalist scholarship on global environmental regimes has burgeoned, as has constructivist scholarship on the key role played by norms in international politics. In this innovative volume, the author sets these interest- and norm-based approaches against each other in order to test their ability to illustrate why and how different environmental norms take hold in some regimes and not others. The book explores why some global environmental treaties seek to preserve and protect some parts of nature from human utilization, some seek to conserve certain parts of nature for human development, whilst others allow the reckless exploitation of nature without accounting for the consequences. It tracks the fate of these three underlying environmental norms preservation, conservation and exploitation using case studies on whaling, mining in Antarctica and tropical timber. The book illustrates how international political battles to shape environmental regimes inevitably result in clashes between these competing environmental norms. This unique study will prove a fascinating read for both academics and practitioners in the fields of international environmental politics and international environmental law." -- Publisher's information.
