Abstract: This study examined the relationship between Dark Triad traits and organisational citizenship behaviour for the environment (OCBE) as well as the mediating role of environment value orientations. Hierarchical regression analysis revealed that higher education levels and recycling habits were positively associated with OCBE. When the Dark Triad traits were added, Machiavellianism positively predicted OCBE while psychopathy showed a negative effect with a significant improvement in model fit. Mediation analyses revealed that egoistic values positively mediated the relationships between narcissism and OCBE and unexpectedly between psychopathy and OCBE. However, egoistic values did not significantly mediate the effect of Machiavellianism. Altruistic values did not mediate any of the relationships. Biospheric values did not mediate the impact of Machiavellianism and narcissism but negatively mediated the relationship between psychopathy on OCBE. The implications of these results and the limitations of the study are discussed.

Keywords: bootstrapping; organisational sustainability; Machiavellianism; employee pro-environmental behaviour; narcissism; psychopathy.
