The present paper investigates the alternatives for the political setting chosen for the climate negotiations under the United Nations Framework Convention on Climate Change (UNFCCC). In doing so, it first defines criteria for the categorization and evaluation of a climate regime design. As a second step, these criteria are applied to nine different groups of alternative approaches. The result of this analysis is presented in form of a categorization table where the groups of approaches are evaluated on a scale from 1 to 5 with respect to particular evaluative criteria. Finally, possible directions for combinations of approaches are outlined based on the preceding analysis.
