Abstract
Why were states able to reach agreement on the United Nations Framework Convention on Climate Change (UNFCCC), but not the Kyoto Protocol? What role did power, preferences, and information play in climate change negotiation outcomes? How do systemic and domestic factors influence international cooperation? Sources of Data: The study relies on qualitative analysis based on secondary and primary sources, including material from the United Nations, European Union, and United States government. Conclusions Reached: Systemic and domestic factors help explain the difference in outcomes of UNFCCC and the Kyoto Protocol. Both the provision of information and the compatibility of state preferences varied in the two cases, resulting in agreement on UNFCCC but not the Kyoto Protocol. Although the provision of information is partially explanatory, the compatibility of state preferences best explains the difference in negotiation outcomes. An exploration of domestic politics is required in order to determine the compatibility of state preferences in international cooperative efforts.
