Political trust and public support for climate policy in Europe: the role of perceptions about politicians’ competence and integrity

Abstract

While previous studies on the relationship between political trust and support for climate policy have focused on the evaluative component of trust, namely whether politicians and the political system can be trusted or not, less is known about the role of different dimensions of trustworthiness that underlie such evaluations. In this study, we examine how perceptions about politicians’ competence and integrity, two central dimensions of trustworthiness, are related to public support for climate policies. Using survey data from four European countries (Sweden, Germany, Spain, and Poland), we find that people who think that politicians are competent are generally more likely to support climate policy. In contrast, we do not find such a relationship between integrity perceptions (e.g., corruption) and policy attitudes. These findings are consistent across national contexts and hold even when alternating the measures capturing competence and integrity perceptions. To bolster public support for climate policies, climate communication should prioritize addressing public concerns regarding politicians’ competence in designing sound climate policies, rather than alleviating concerns about their integrity, such as fears of corruption.
