Abstract
To promote sustainability transition, it is important to encourage collective pro-environmental behaviors. We analyzed the influence of a close person on youth's behavioral intention toward collective proenvironmental behaviors by simultaneous covariance structure analysis comparing the group which have a close parson who participate in community's activities regularly and the group which do not have such a person for the case of introducing a renewable energy system. As the results, the behavioral intention of the group with a close person was statistically higher than that of the group without a close person. Perceived collective competence enhanced evaluation of ability, resulting in more behavioral intention in the group with a close person. Furthermore, evaluation of ability, responsibility for collective proenvironmental behaviors and active interest in environmental problems were significantly associated with behavioral intention, whereas the belief that environmental risk could be avoided by individual behaviors was negatively related to behavioral intention in both groups.
