Effectively reducing climate change requires marked, global behavior change. However, it is unclear which strategies are most likely to motivate people to change their climate beliefs and behaviors. Here, we tested 11 expert-crowdsourced interventions on four climate mitigation outcomes: beliefs, policy support, information sharing intention, and an effortful tree-planting behavioral task. Across 59,440 participants from 63 countries, the interventions’ effectiveness was small, largely limited to nonclimate skeptics, and differed across outcomes: Beliefs were strengthened mostly by decreasing psychological distance (by 2.3%), policy support by writing a letter to a future-generation member (2.6%), information sharing by negative emotion induction (12.1%), and no intervention increased the more effortful behavior—several interventions even reduced tree planting. Last, the effects of each intervention differed depending on people’s initial climate beliefs. These findings suggest that the impact of behavioral climate interventions varies across audiences and target behaviors.

Current sustainability challenges often reflect common resource dilemmas where peoples’ short-term self-interests are at odds with collective interests in the present and future. In this article, we highlight the key role of joint decision-making processes in negotiations to facilitate the management of common resource dilemmas and to promote the transition toward sustainability. By reflecting on psychological drivers and barriers, we argue that the limited availability, the restricted accessibility, and the dynamic alterability of resources in negotiations on common resource dilemmas may cause a myopic mindset that fosters value claiming strategies and, ultimately, results in distributive-consumptive negotiation outcomes. To promote value creation in negotiations on common resource dilemmas, we argue that agents must perform a mindset shift with an inclusive social identity on a superordinate group level, an embracive prosocial motivation for other parties’ interests at and beyond the table, and a forward-looking cognitive orientation towards long-term consequences of their joint decisions. By shifting their mindset from a myopic towards a holistic cognitive orientation, agents may explore negotiation strategies to create value through increasing the availability, improving the accessibility, and using the alterability of resources. Applying these value creation strategies may help achieve integrative-transformative negotiation outcomes and promote sustainable agreements aimed at intersectional, interlocal, and intergenerational justice. We conclude by discussing additional psychological factors that play a pivotal role in negotiations on common resource dilemmas as well as further developments for future research.

Transformative and mutually beneficial solutions require decision-makers to reconcile present- and future interests (i.e., intrapersonal conflicts over time) and to align them with those of other decision-makers (i.e., interpersonal conflicts between people). Despite the natural co-occurrence of intrapersonal and interpersonal conflicts in the transformation toward sustainability, both types of conflicts have been studied predominantly in isolation. In this conceptual article, we breathe new life into the traditional dialog between individual decision-making and negotiation research and address critical psychological barriers to the transformation toward sustainability. In particular, we argue that research on intrapersonal and interpersonal conflicts should be tightly integrated to provide a richer understanding of the interplay between these conflicts. We propose a novel, unifying framework of interdependent conflicts that systematically structures this interplay, and we analyze how complex interdependencies between the social (i.e., conflict between decision-makers) and temporal (i.e., conflict within a decision-maker) dimensions pose fundamental psychological barriers to mutually beneficial solutions. Since challenges to conflict resolution in the transformation toward sustainability emerge not only between individual decision-makers but also frequently between groups of decision-makers, we scale the framework up to the level of social groups and thereby provide an interdependent-conflicts perspective on the interplay between intra- and intergenerational conflicts. Overall, we propose simple, testable propositions, identify intervention approaches, and apply them to transition management. By analyzing the challenges faced by negotiating parties during interdependent conflicts and highlighting potential intervention approaches, we contribute to the transformation toward sustainability. Finally, we discuss implications of the framework and point to avenues for future research.
