Given the current environmental situation and social change in China, we explored the relationships between the Dark Triad traits (Machiavellianism, narcissism, and psychopathy) and environmental attitudes (the beliefs regarding environmentally related issues), and the mediating roles of future orientation (the tendency to plan for meeting long-term objectives) and place attachment (the emotional connection with the place of residence) in these relationships. Using a national sample drawn from all 31 provinces of mainland China (N = 998), we found that the psychometric structure of the Dark Triad was well confirmed under Chinese culture. The Dark Triad as a whole was negatively related to environmental attitudes, but narcissism was not significantly associated with environmental attitudes when the three Dark Triad traits were considered as the predictors simultaneously. Future orientation and place attachment mediated the association between the Dark Triad and environmental attitudes. These findings contribute to verifying the measurement of the Dark Triad under Chinese culture, enriching our understanding of the relevant variables of environmental attitudes, and providing evidence that narcissism is not as dark as the other two traits.
