Climate change is an intergenerational challenge that requires intergenerationally focused behavioral solutions

Anthropogenic climate change presents an intergenerational challenge, with its most severe impacts expected to affect future generations if current society fails to take action. Intergenerational psychology — specifically how people think about and care for future generations — has emerged as a critical driver of pro-environmental engagement, transcending demographic and ideological barriers. Insights from ethical philosophy, political philosophy, and behavioral economics further underscore the importance of intergenerational approaches in addressing environmental issues. We review the recent research on psychological interventions, legacy motivations, the principles of intergenerational responsibility, and behavior in economic games in the context of pro-environmental engagement. Broadly, this research has shown promise in promoting climate action across diverse populations through intergenerational framings. Importantly, intergenerational approaches not only inspire individual responsibility but also foster collective efforts toward sustainable solutions. Despite considerable emerging research, we point toward gaps in the literature for future research to address. Namely, there is a need for more research exploring the enduring impacts of intergenerational interventions using randomized controlled trials with longitudinal designs and examining their potential in promoting resilience and justice in the face of climate change. In sum, we conclude that addressing both climate change mitigation and adaptation through an intergenerational lens could be key to protecting the environment — not only for the present generation but also for the many future generations to come.
