To support the development of a society that is attuned to the challenges presented by sustainable development, it is vital that higher education business students understand the value of sustainability, and act in a way that is consistent with these values. This paper explores a sustainability-focused experiential learning activity through investigating the utility of an emerging form of service learning in the digital space for developing global citizens. The paper presents an international case study of educators who employed digital service learning in various business education contexts. The research reports on the perceptions of higher education students in relation to their awareness, critical thinking and action for sustainability. The paper has practical contributions in identifying an opportunity for implementing sustainability curriculum into higher education for business.
