Understanding the effects of partisan identity on climate change

Partisan and ideological identities are a consistent barrier to the adoption of climate change mitigation policies, especially in countries where fossil fuel reliance is the highest. We review how understanding collective cognition may help overcome such barriers by changing norms, promoting cooperation, downplaying partisan identities, or leveraging other identities to promote pro-climate change beliefs and behaviors. We also highlight several gaps in the literature and lay out a brief roadmap for future research. This review highlights the important role that social identity plays, both in terms of a barrier and a potential solution, in aid of promoting climate change mitigation. We also propose several key areas where research is lacking, and identify specific future directions.
