We investigate the relationships between narcissism, materialism, and environmental ethics in undergraduate business students. Data were collected from business students (n = 405) at an Association to Advance Collegiate Schools of Business-accredited business school at a comprehensive state university. Results indicate that narcissism has an indirect effect on business students' environmental ethics. Narcissism was significantly related to materialism, and materialism was significantly related to lower levels of environmental ethics. Considering increasing levels of narcissism among business students, we discuss the potential for future research and potential intervention strategies.
