Abstract Emerging adulthood is considered an important period in identity formation (Arnett, 2000). In this study, we consider how political ideological development during emerging adulthood may influence environmental beliefs, identity and actions in adulthood. To explore these relationships, we used longitudinal data initially collected in 1999 from over 300 Canadian adolescents (age 19) who were monitored into adulthood (age 32). Political ideology was assessed at ages 19, 23 and 32. Environmental beliefs, identity and behavior were collected at age 32. Using latent growth curve modeling, we found that changes in political ideology from age 19 to 32 negatively predicted the environmental measures: as people became more conservative over emerging adulthood, they were less environmentally-oriented in adulthood. These results are discussed within a larger political discourse focused on environmental actions and concerns about climate change.

环保主义背后的政治：新兴成年期的政治意识形态发展如何发挥作用

摘要 成年初期被认为是身份形成的重要时期（Arnett，2000）。在这项研究中，我们考虑了新兴成年期的政治意识形态发展如何影响成年期的环境信念、身份和行动。为了探索这些关系，我们使用了 1999 年最初从 300 多名加拿大青少年（19 岁）收集的纵向数据，这些青少年被监测到成年（32 岁）。政治意识形态在 19、23 和 32 岁进行评估。环境信念、身份和行为在 32 岁时收集。使用潜在增长曲线模型，我们发现 19 至 32 岁政治意识形态的变化对环境措施产生负面预测：作为人们在成年后变得更加保守，他们在成年后不太注重环保。
