Exploring the impact of megaproject environmental responsibility on organizational citizenship behaviors for the environment: A social identity perspective

The importance of organizational citizenship behaviors for the environment (OCBEs) has been clearly established in the environmental literature. However, the OCBEs construct has rarely been examined in the specific and increasingly important realm of megaproject environmental responsibility (MER). To fill this gap, this paper presents an individual-level analysis that explores the impact of project participants' perceptions of MER practices on their environmental commitment and OCBEs. The results show that project participants' perceptions of MER practices directed toward internal stakeholders (i.e., stakeholders linked by project contracts) are positively related to their OCBEs. This relationship is partially mediated by the environmental commitment of project participants. Conversely, project participants' perceptions of MER practices directed toward external stakeholders (i.e., the local community and general public) have only an insignificant impact on their OCBEs. These findings provide new insights for managing MER practices to stimulate the emergence of OCBEs and thereby improve environmental performance.
