In the field of higher education, the role of sustainability is increasingly seen as an important capability of successful graduates, one of a group of higher-level dispositions that is particularly important for students' future professional roles. Discussion of sustainability often assumes that all participants understand the term in the same way, and different understandings can make meaningful dialogue difficult. This article presents an empirical investigation of the ways in which students from a business faculty at a large metropolitan university view sustainability in the specific context of their tertiary education. While some students viewed the notion in quite naïve ways-for example, the idea of 'keeping themselves going'-others talked about much broader views incorporating ideas of inter-generational justice. Investigation of such views provides important evidence for dialogue on sustainability with the next generation of professional leaders in business.
