On an international scale, the Intergovernmental Panel on Climate Change (IPCC) is regarded as the most important institution providing global expertise on the global development of climate change, about which it periodically publishes reports. Founded in 1988 by the World Meteorological Organization and the United Nations Environment Programme, the IPCC’s purpose is to ‘provide regular assessments of the scientific basis of climate change, its impacts and future risks, and options for adaptation and mitigation’ (IPCC, n.d.). This chapter examines the rationale of the IPCC focusing on its knowledge production practices, especially including possible effects on the maintenance of postcolonial structures or attitudes. What does it mean when knowledge about a phenomenon globally perceived as pressing, which, as the majority of experts agree, demands quick transnational action, is funnelled into a single pool of shared global knowledge? From a postcolonial angle the chapter reflects on the epistemological question of whether the work of the IPCC contributes to the overall establishment of a postcolonial climate change regime. It discusses the legacy of the IPCC as the leading institution of epistemological climate change governance, reflects on the IPCC’s mission and its values—constructiveness, universalism of knowledge and impacts on depoliticisation.
