Like most countries in the region, Argentina faces the challenge of promoting climate action to mitigate greenhouse emissions and adapt to changes in environmental patterns. Traditional science communication methods, which often rely on statistical data and abstract concepts, are deemed insufficient for driving behavioral change. In this chapter, we leverage insights from behavioral science to emphasize the importance of addressing psychological determinants of pro-environmental behavior, such as environmental self-identity, perceived behavioral plasticity, and outcome efficacy. Additionally, we highlight the role of social factors, particularly political polarization, in shaping public attitudes and actions toward climate change. This non-systematic review identifies a gap between climate acceptance and climate action in the literature, suggesting that interventions should not only focus on communications but also on enhancing convenience and reducing the friction associated with sustainable choices. We highlight relevant frameworks to understand goal conflicts influencing environmental behavior, with recommendations for promoting pro-environmental actions by altering perceived outcomes and strengthening normative goals. Practical recommendations for developing behaviorally informed campaigns to promote climate action in Argentina are provided. These include using simple and clear messages, tailored persuasive appeals, culturally relevant storytelling, audience segmentation, and policy interventions that leverage default options and extrinsic incentives. We emphasize the need for further research on the behavioral determinants of climate action in Argentina to inform effective communication strategies and policy interventions.
