Young people will experience stronger consequences of climate change in their future adult lives than older people are facing today. Against this background, large demonstrations and school strikes for climate protection started all over the globe, called the Fridays For Future (FFF) movement. Drawing on the social identity model of pro-environmental action (SIMPEA) and theories on pro-environmental actions of children and adolescents, we examined psychological drivers of pro-environmental activism in the FFF movement. Young people recruited during a FFF demonstration in a German city (N = 144, 16–25 years old) and from all over Germany recruited through an online panel (N = 418, 13–25 years old) participated in our online survey study. A comparison of these samples and a regression analysis with the joint sample both revealed that perceiving friends participating in the movement, identification with others engaging in climate protection, and personal norms in the form of a felt obligation based on values were most strongly related to their participation in FFF protests. We discuss theoretical implications of our findings as well as practical implications for interventions to encourage young people's pro-environmental engagement.

与今天的老年人相比，青年人在未来的成年生活中将面临更大的气候变化后果。在这种背景下，全球各地发起了大规模的示威游行和学校罢工，以保护气候，这就是所谓的“未来星期五”运动。利用环保行动的社会认同模型（SIMPEA）和儿童和青少年环保行动的理论，我们研究了FFF运动中环保行动主义的心理驱动因素。在FFF示威期间在德国城市招募的年轻人（N  = 144，16-25岁），并通过在线小组从德国各地招募了年轻人（N = 418（13–25岁）参加了我们的在线调查研究。这些样本的比较以及与联合样本的回归分析均显示，感知参与运动的朋友，与其他从事气候保护的人的认同以及基于价值的有义务感形式的个人规范与他们的关系最密切参加FFF抗议活动。我们讨论了研究结果的理论含义以及对鼓励年轻人的环保参与的干预措施的实际含义。
