Pathways to deliberative capacity: the role of the IPCC

Abstract

This article explores the arguments for expanding deliberation in the Intergovernmental Panel on Climate Change (IPCC) and scrutinizes their implications for the deliberative capacity of global environmental governance (GEG). An analysis of the IPCC is presented that builds on a systematic literature review and thus a broad set of scientific debates concerning the IPCC. Based on this analysis, two different paths are outlined, one moderate and one radical; these paths ascribe different democratizing functions to the IPCC and rely on different epistemologies. The moderate path emphasizes decision capacity, whereas the radical path strives to create deliberative space and to identify the value inherent in different claims. It is argued that the IPCC cannot accommodate the aspirations of these different pathways in a single assessment. Parallel assessments must be developed in complementary subject areas with different science-policy relations.
