Purpose This paper aims to outline the global research landscape of sustainability curricula implementation processes in higher education. The focus is twofold and investigates where research that aims at integrating sustainability into the curriculum is happening and how the research area of curriculum change for sustainability is developing. Design/methodology/approach A systematic review of peer-reviewed case studies published in English in selected journals and edited volumes between 1990 and 2017 was carried out. Data (n = 270 publications) were analyzed via descriptive statistics and bibliometric analysis. Findings The study demonstrates that research on sustainability curricula implementation processes in higher education has produced a growing output in a broad range of journals. Nevertheless, the cross-country distribution is imbalanced, with most cases coming from the USA, Europe and Asia, but with the relatively highest density in Oceania. A citation network analysis revealed that the “Western world” is quite well interlinked, whereas other countries are not, indicating that sharing information between and learning from other cases is limited. Research limitations/implications The exclusion of non-English publications likely skewed the global distribution of the research landscape included in this study. Social implications These findings demonstrate the need for more research and funding for case studies in countries that have not yet been adequately examined. Originality/value This study offers the first systematic reflection on the current global research landscape in sustainability curricula implementation and can guide further research endeavors.

Progress on the Sustainable Development Goals (SDGs) depends, in part, on the sustainability competencies of professionals in various fields, and thus, on the implementation of sustainability curricula in higher education. While many universities now offer sustainability curricula, and many more aspire to, there is a lack of evidence on what supports or hinders such implementation. This article presents a meta-study on 133 case studies from universities around the world and synthesizes the main drivers and barriers, identifies information gaps, and tests prominent assumptions on implementing sustainability curricula in higher education. The findings confirm that such implementation is associated with strong leadership by the university; incentives and support through professional development; concurrent implementation of sustainability in research, campus operations, and outreach; formal involvement of internal and external stakeholders as well as sustainability champions, among others. Common research protocols for case studies are needed to yield comparable data on these influencing variables and to enhance reliability of cross-case comparisons. Most sustainability programs could utilize the findings for informing their implementation processes.

Implementing education for sustainable development (ESD) in higher education institutions (HEIs) is critical to facilitating a transition toward sustainable development. However, little is known about the specific implementation processes that lead to the institutionalization of sustainability curricula in HEIs. This meta-study and cluster analysis uses 131 international case studies to shed light on six distinct implementation patterns: (1) collaborative paradigm change, (2) bottom-up, evolving institutional change, (3) top-down, mandated institutional change, (4) externally driven initiatives, (5) isolated initiatives, and (6) limited institutional change. A cluster comparison reveals two distinct implementation phases: ESD can be implemented from the bottom-up, from the top-down, or both, and the impetus can stem from manifold external or internal stakeholders. To achieve more comprehensive ESD implementation, open communication among all stakeholders should be facilitated and feedback as well as reflection encouraged. Maintaining a unified vision statement and active participation of all stakeholders fosters a sense of ownership in ESD implementation and ensures that it will be long-lasting. Collaboration between isolated ESD initiatives and various stakeholders leads to shared knowledge and resources. Strong informal collaboration and communication can compensate for a lack of formalized leadership support from the top. Moreover, thorough planning that involves creating a strategy with detailed steps, and balancing shared responsibilities among internal stakeholders further enables fuller implementation of ESD. This analysis represents a first synthesis of small-N case studies and facilitates a better understanding of sustainability curriculum implementation patterns, which are shared in different contexts. Most HEIs and practitioners can benefit from these findings by reflecting on the specific implementation pattern with which the most overlap is found and focusing on this pattern’s most pertinent drivers.
