Climate policy expertise in times of populism – knowledge strategies of the AfD regarding Germany's climate package.

Climate policy is expected to consider the current state of science. As populist radical right parties (PRRP) become elected members of parliaments, they have a greater influence on integration processes between science and politics. The aim of the paper is to show that instead of generally rejecting climate science, PRRPs appeal to 'alternative expertise' and politicize scientific knowledge. With our empirical analysis of public hearings, plenary meetings and press statements discussing Germany's Climate Package between 2018 and 2020, we show that the AfD uses expertise that suits their political interests very selectively and arbitrarily supporting either scientific outsider positions or positions that only pretend to be scientific. We argue that populist strategies weaken trust in scientific expertise by undermining democratic institutions for knowledge integration in climate governance. Therefore, a clear separation between research and politics together with transparent and formal scientific knowledge integration processes are needed. [ABSTRACT FROM AUTHOR]
