U.S. policy in the UN environmental arena: powerful laggard or constructive leader?

As the world’s one remaining superpower, the United States stands forth as a hegemon in international politics. Within the traditional realist perspective, this means that the U.S. is decisive for the ambition and scope of international cooperation. However, research has shown that there is limited empirical support for this assumption when it comes to environmental cooperation. After a brief look at the U.S. general attitude and perception of the UN, this paper will then review general trends in U.S. foreign environmental policy within the United Nations context, including several key domestic factors that have influenced the U.S. in this area. I will then look more specifically at three UN institutions that are responsible for different aspects of environmental governance: United Nations global conferences (Stockholm in 1972, Rio de Janeiro in 1992 and Johannesburg in 2002), the United Nations Environment Programme (UNEP) and the Commission on Sustainable Development (CSD). The main focus will be how U.S. policies and influence in these arenas, and their relationship to UN reform, have evolved over time. Finally, the paper will attempt to analyze the American policies and answer the question posed in the title: is the U.S. a powerful laggard or a constructive leader?
