This article contributes to comparative environmental politics by integrating comparative analysis with debates about ontological politics as well as science and technology studies. Comparative environmental analysis makes two tacit assumptions: that the subject of comparison (e.g., an environmental policy framework) is mobile and can be detached from its contexts; and that studying this subject in more than one location can identify its diffusion and implementation anywhere. These assumptions are sites of ontological politics by predetermining (or restricting) environmental outcomes. Environmental analysis needs to consider how its own comparative acts might reify supposedly global frameworks rather than acknowledging how different localities appropriate and give meaning to them in diverse ways. The concept of civic epistemologies illustrates how domestic politics are organized around supposedly global concepts, rather than how global concepts diffuse around the world, as illustrated here by a comparative analysis of the United Nations’ Green Economy Initiative.

This paper argues that the resistance to climate science from so-called deniers cannot be explained by drawing an imaginary line between two fields of science and politics and then investigating each for malfunctions. Instead, there is a need to understand the co-evolution of scientific knowledge and political norms more holistically, and to identify how simple classifications of right and wrong reduce discussion about climate risks and policies. This paper makes three recommendations. First, the debate about climate denial is a question of how science and politics connect, rather than a moral choice in accepting or rejecting science. Second, different ideologies (including “deniers” or “acknowledgers”) will always make simplistic statements about climate science. Third, there is a need to open up the discussion of climate risks beyond one master statement that humans have caused global warming to consider how to reduce emissions and vulnerability, which can include industrialization in developing countries.
