Purpose: The purpose of this paper is to explore how competences for sustainable development and research interrelate within a context of competence-based higher education. Specific focus is oriented towards strengthening research competences for sustainability. Design/methodology/approach: Following a hermeneutic-interpretive methodology, this paper builds upon a critical literature review to demarcate the theoretical framework and an in-depth analysis of a case study exploring the interrelations between both types of competences. Findings: The paper discusses current issues in the integration of competences and explores the contribution of research-based methods to acquire competences for sustainable development. The analysis shows that research skills are often mentioned to contribute to this acquisition, though from a general perspective, or from the sidelines of the learning process. A holistic view on how both concepts are linked is missing. Research limitations/implications First, the complex nature of competences and their integration in higher education could lead to difficulties in interpreting and analysing them. Second, the analysis is based on a single-case study, limiting possibilities to generalise the results. Third, this study is not looking at curriculum practices in these fields. Practical implications: There is a need to holistically (re-)frame research competences within the concepts of education for sustainable development and, to a wider extent, sustainable development. Social implications Framing research competences within the concept of sustainable development enables a thorough and "conscious", rather than coincidental, acquisition of competences for sustainable development. Originality/value: The originality of this paper lies in the fact that there is little literature about the interrelations between competences for sustainable development and research competences.
