Climate change anxiety is a growing problem for individual well-being the world over. However, psychological interventions to address climate change anxiety may have unintended effects on outcomes other than individual well-being, such as group cohesion and pro-environmental behavior. In order to address these complexities, we outline a multiple needs framework of climate change anxiety interventions, which can be used to analyze interventions in terms of their effects on individual, social, and environmental outcomes. We use this framework to contextualize a systematic review of the literature detailing the effects of climate change anxiety interventions. This analysis identifies interventions centered around problem-focused action, emotion management, and enhancing social connections as those which have beneficial effects on the widest range of outcomes. It also identifies interventions that may have detrimental effects on one or more outcomes. We identify gaps where more research is required, including research that assesses the effects of climate change anxiety interventions on individual, social, and environmental outcomes in concert. An interactive website summarizes these insights and presents the results of the systematic review in a way that is, accessible to a range of stakeholders. The multiple needs framework provides a way to conceptualize the effectiveness of climate change anxiety interventions beyond their impact on individual well-being, contributing to a more holistic understanding of the effects of this global phenomenon.
