Existing research shows that childhood processes affect identity formation. However, there is limited scholarly understanding about how these processes work as children age. The case of environmental behavior offers the opportunity to interrogate these processes. I use reflective interviews with 40 participants in the 2014 People’s Climate March in New York to understand how the socialization of environmental behavior in childhood shapes their perceptions of the processes of identity formation related to participation in the environmental movement. I argue that environmental movement behavior is facilitated by the development of compatible identity standards during childhood. I find that four processes—nature experiences, witnessing degradation, parental modeling, and school experiences—influence participation in environmental movement behavior in adulthood. My results highlight varied ways that behavior in adulthood can be facilitated through the shaping of identity standards over the life course. This research has implications for research on socialization, identities, social movements, and the environment.

现有研究表明，童年过程会影响身份形成。但是，对于这些过程如何随着儿童年龄的增长而进行的学术研究有限。环境行为的情况为审讯这些过程提供了机会。在2014年纽约举行的“人民气候游行”中，我接受了40位参与者的反思性采访，以了解儿童时期环境行为的社会化如何塑造他们对与参与环境运动有关的身份形成过程的看法。我认为，童年时期制定兼容的身份标准有助于环境运动行为。我发现有四个过程-自然经历，见证退化，父母塑造，和学校经验-影响成人参与环境运动行为。我的研究结果突显了通过在人生过程中塑造身份标准来促进成年行为的多种方式。该研究对社会化，身份，社会运动和环境的研究具有启示意义。
