Abstract: Climate policy support and promoting individual behavior change are a crucial approach to addressing climate change and reducing carbon emissions at the societal level. Behavioral climate policy, which integrates behavioral science theory with public policy design, has emerged as a new research direction to enhance the effectiveness of climate actions. Based on a systematic literature review, this study reviews the current research status of behavioral climate policy, aiming to encourage more effective public participation in climate actions and to promote the improvement of the theoretical framework of behavioral climate policy as well as the construction of indigenous knowledge. The results show that the existing research has mainly explored four core topics: behavioral interventions of green nudge tools, cognitive interventions of climate communication frameworks, policy compliance of climate policy design, and barrier elimination in the climate policy environment. Currently, the research on behavioral climate policy is concentrated on the choice architecture of the affected groups. Future research needs to, first, explore the behavioral adaptation between policy actors and the affected groups, focusing on issues such as the policy impact of policy actors' cognition and the balance between policy actors' choice preferences and the behavioral acceptability of the affected groups; second, explore the in-depth integration of micro behavioral science and macro policy process, paying attention to the application of behavioral science in climate agenda setting, policy formulation, implementation, and evaluation.
