This article discusses “academic housekeeping” undertaken within IPCC, understood as the work that is rarely made visible or rewarded, but is nevertheless essential to the success of the organization. It explores the conditions, motivations, and implications for individual researchers involved in the IPCC, with particular emphasis on the invisible, un(der)recognised and unrewarded work they engage in. The empirical material consists of aninterview study of researchers involved in the IPCC assessment work. The article concludes with a discussion on the implications of unrewarded work for individual experts,expert organisations, and academic institutions.
