Societal transformations for addressing climate change are intensely contested and at risk of resistance and backlash to ambitious policy action. But they are frequently modeled through heuristics such as S‐curves which abstract from such conflicts, assuming increasing returns to scale as a driver of transformations. This is the case even while scholars accept the presence of political conflict in transformation processes. Within political science and allied disciplines, the notions of policy feedback and policy coalitions have been deployed to understand how such political conflicts may be understood. But these approaches risk gravitating toward an instrumental design impulse that inadvertently downplays conflict. We argue that policy action for societal transformations should be re‐conceptualized as an unfolding series of battle‐settlement events whereby heated episodic political struggles over a certain policy object or issue play out and eventually settle in ways that structure future debates while nonetheless remaining indeterminate and open to challenge or reversal. Such an approach reflects the varied empirical experiences of climate policy action to date which include both accumulation and reversal. It also helps explain trajectories of change that are discontinuous and lurching in contrast to common images of transformation as progressive and cumulative. We illustrate this approach through two cases of unfolding societal transformation on climate change: coal phaseout in the United Kingdom and renewable energy uptake in Australia.

Against the backdrop of a fragmented and evolving governance landscape, this paper examines how effective climate commissions are in engaging the public to co-produce local climate action in the UK. Climate commissions are emerging amid heightened concerns regarding the top-down style of policymaking on climate change and resource-constrained local authorities. However, less is known about how they engage the public who are pivotal for climate action, both in signalling greater ambition from governments and through their own mitigation and adaptation efforts. This paper draws on qualitative interviews with an array of individuals both inside and outside climate commissions in the UK, and utilises Cash's theoretical framework of 'salience, legitimacy and credibility' to assess how effective climate commissions are in engaging the public to co-produce local climate action. The findings indicate a discernible chasm between commissions and the broader public. Equally however, they provide hopeful perspectives into the effect that more collaborative engagement, that speaks to local concerns and leverages local knowledge, would have on commissions' 'salience, legitimacy and credibility' and, additionally, the legitimacy of local authorities. Moreover, they suggest that deeper collaboration with local networks of community groups, who are not yet represented on commissions, could foster more sustained climate action. It concludes by considering the novel implications of these emergent insights for the Cash framework and what this means for commissions in their future engagement with the public. • Knowledge co-production resonates in both theory and practice. • Local and grassroot action is critical to meet climate mitigation and adaptation goals. • Ensuring 'salience, legitimacy and credibility' can lead to more effective climate policy. • Climate commissions need to better leverage local knowledge to drive climate action. • Community groups are under-utilised in climate conversations and decision-making.

What makes a climate story effective? We examined if short fiction stories about everyday pro-environmental behaviours motivate climate policy support, and individual and collective climate action in a nationally representative experiment (N = 903 UK adults). The story featuring protagonists driven by pro-environmental intentions (i.e., the intentional environmentalist narrative) increased participants' support for pro-climate policies and intentions to take both individual and collective pro-environmental actions, more so than did stories featuring protagonists whose pro-environmental behaviours were driven by intentions to gain social status, to protect their health, and a control story. Participants' stronger feelings of identification with the protagonist partially explained these effects of the intentional environmentalist narrative. Results highlight that narrating intentional, rather than unintentional, pro-environmental action can enhance readers' climate policy support and intentions to perform pro-environmental action. Therefore, the intentions driving pro-environmental action may have implications for the extent to which observes identify with the actor and take pro-environmental action themselves.

Credible commitment is central to regimes for climate mitigation policy. In the climate policy literature, it is widely argued that the solution to the credible commitment problem is legislation and delegation of goal-setting to a technical body insulated from political incentives, and the UK's Committee on Climate Change is in part modelled on this approach. However, drawing on the comparative politics literature, this paper argues that the focus on legislation and delegation as the solution to the credible commitment problem is too narrow. Seen within the context of comparative political institutions, it is a response that fits the political logic in countries with majoritarian electoral systems. By contrast, in countries with electoral systems based on proportional representation, while legislation plays a role, an important element in the creation of credible commitment comes in the form of negotiated long-term agreements between political parties. This contrast is explored through a comparison between the Climate Change Act and associated Committee on Climate Change in the UK on the one hand, and a series of Energy and Climate Agreements in Denmark over the 2010s. Both approaches appear to have worked to date. However, while negotiated long-term agreements typically have an internal process for managing conflicts that inevitably arise after the respective mechanisms have been put in place, disputes arising following legislation and delegation must be resolved within the more informal processes of intra-party politics. Mechanisms of accountability also differ between the two approaches. Key policy insights Legislation and delegation is widely seen as the key route to credible commitment for climate policy, but other routes are possible. Legislation and delegation is particularly suited to countries with majoritarian, or first-past-the-post electoral systems and resulting political dynamics. In countries with proportional representation, an alternative route to credible commitment is possible via formal agreement between political parties. Both routes can work well, but political agreements tend to have internal mechanisms for mediating conflicts that subsequently arise, whereas delegation relies on intra-party politics.

The saltmarsh carbon storage potential is a key topic in blue carbon research and climate policy. Ecosystem service valuations provide valuable information to policymakers for habitat management and climate change mitigation policies. Yet, only few saltmarsh valuation studies have included the carbon storage service in the UK context. This paper investigates how the public values saltmarsh ecosystem services, focussing on the carbon storage service. We used a choice experiment to elicit the willingness to pay (WTP) of a representative sample of the Scottish public to support interventions that would maintain or improve the provision of these services. Furthermore, we tested the effect of information on individuals' preferences and WTP with a split sample approach where one group received a treatment in the form of additional information. We found that (i) all attributes had a significant influence on individuals' choices; (ii) both groups had, on average, a positive marginal WTP for all presented ecosystem services; (iii) the treated sample had, on average, no significantly different marginal WTP for carbon storage than the control group. This paper adds to the limited literature on the saltmarsh carbon storage ecosystem service and demonstrates a developed nation's public's openness to nature-based climate change mitigation solutions. [Display omitted] • The Scottish public on average prefers saltmarsh management over the status quo. • Providing additional information reduced heterogeneity in WTP for carbon storage. • Most respondents preferred an improvement of all saltmarsh ecosystem services. • Therefore management should focus on both climate change mitigation and adaptation.
