What are the roles of bottom-up and top-down signals in the formation of climate change policy preferences? Using a large sample of American residents (n = 1520) and combining an experimental manipulation of descriptive social norms with two choice experiments, we investigate the effects of descriptive norms and policy endorsements by key political actors on climate policy support. We study these questions in two areas considered to be central in a number of decarbonization pathways: the phase-out of fossil fuel-powered cars and the deployment of carbon capture and storage. Our study provides two important results. First, social norm interventions may be no silver bullet for increasing citizens’ support for ambitious climate policies. In fact, we not only find that climate policy support is unaffected by norm messages communicating an increased diffusion of pro-environmental behaviors, but also that norm messages communicating the prevalence of non-sustainable behaviors decrease policy support. Second, in the presence of policy endorsements by political parties, citizens’ trust in these parties influences their support for climate policies. This study contributes to research in behavioral climate policy by examining the impact of descriptive norms and elite cues on climate policy support.

Why do policy responses to one and the same event often vary so markedly between different jurisdictions? This contribution sheds light on conditions and processes that link crises to policy change or policy stability. Drawing on public policy theories and accounts from crisis management, the type of policy subsystem that is hit by a crisis is theorized to be a decisive factor when it comes to explaining variation in crisis‐induced policy reactions. The theoretical arguments are explored based on a comparative case study of Fukushima's differential impact on nuclear power policymaking in Japan and Germany. In order to systematically analyze interaction patterns of policy elites, the study capitalizes on recent methodological advances and applies a method called discourse network analysis. The analysis yields topographies of policy discourses around the Fukushima crisis in both countries and shows that crises can trigger major policy shifts when “anchors” for policy change—i.e., alternative policy ideas and proposals put forward by a minority coalition—are readily available. If a pre‐crisis subsystem is unitary, on the other hand, the pressure on incumbents is rather low and policy shifts are prevented from going beyond mere incremental adjustments..

Promoting low-carbon innovation has long been a central preoccupation within both the practice and theory of climate change mitigation. However, deep lock-ins indicate that existing carbon-intensive systems will not be displaced or reconfigured by innovation alone. A growing number of studies and practical initiatives suggest that mitigation efforts will need to engage with the deliberate decline of carbon-intensive systems and their components (e.g., technologies and practices). Yet, despite this realisation, the role of intentional decline in decarbonization remains poorly understood and the literature in this area continues to be dispersed among different bodies of research and disciplines. In response, this article structures the fragmented strands of research engaging with purposive decline, interrogating the role it may play in decarbonization. It does so by systematically surveying concepts with particular relevance for intentional decline, focusing on phase-out, divestment, and destabilization.
