Grasping Sustainability Culture in Higher Education Institutions: Conceptualizing and Understanding Key Elements

ABSTRACT This study addresses the limitations of structural reforms in higher education institutions (HEIs) by emphasizing the need for a robust sustainability culture to support long‐term transformation. Despite growing interest, the concept of sustainability culture is still underdefined, leading to fragmented practices and a lack of shared orientation. To clarify this concept, the study applies a culture‐theoretical framework and combines literature review with expert interviews to examine what constitutes sustainability culture in HEIs and how to identify it. The analysis indicates that participatory structures, respectful work environments, and transparent communication are critical cultural conditions that shape the effectiveness of sustainability efforts. By defining and translating these dimensions into observable indicators, the study contributes to organizational theory in the context of sustainability and provides practical guidance for institutional development. It demonstrates that cultural initiatives are essential complements to structural strategies and that a mature sustainability culture fosters well‐being and collaboration within and across institutions.
