The Intergovernmental Panel on Climate Change (IPeC) is Widely regarded as an organization devoted to producing 'policy relevant bl:lt not policy prescriptive' assessments of climate science. Most analyses assume that these assessments are insulated from the politics of policymaking, and consequently they fail to account for a range of politics that come into the assessment process through the development of climate science and the· IPec's organizational design. These politics including the ideology of modern and institutional politics of climate science, and the organizational politics the World Meteorological Organization, the Inte·rnational Council for Science, and the United Nations Environment Program. Using theoretical perspectives drawn from political sociology and business management studies, this thesis argues that IPee assessments are framed by ideological and institutional politics that act through an t· organizational design that concentrates power over the form and substance of these assessments in the science-administrators of the IPCC's ~dministrative bureaus. It further argues that t~ese politics shape the science of Ipce assessments to support predetermined policy preferences represented in the Marrakech Accords as technological and market-based emissions reductions arid technology transfers that serve European and american government interests in national security and economic growth.
