Given the prominence of sustainability in current global crises and the commitment of societies to the Sustainable Development Goals, this mixed methods study ascertains how Dutch higher education students (N = 549) integrate sustainability into their life purposes. From quantitative data, we identified four purpose profiles: purposeful (33%), dreamer (32%), self-oriented (18%), and disengaged (17%), signifying a potential commitment to sustainability among over half of the participating students. However, technology students differed from other respondents in that fewer of them were identified as having a purposeful profile and more of them were disengaged. The data reveal happiness (61%), work (22%), and sustainability (22%) as the most frequently mentioned contents of purposes, implying a more self-oriented picture than indicated in the profiles. The two case studies illustrate concrete ways of manifesting sustainability as a purpose in life. We discuss the educational implications of this, especially the need to enhance sustainability education in the domain of technology.
