Purpose: The purpose of this study is to identify the most prevalent initiatives undertaken by leading universities in sustainability and offer a roadmap for other institutions seeking to undertake similar actions and contribute to more effective implementation of sustainability practices. Design/methodology/approach: By using a quantitative assessment approach, the study sheds light on successful initiatives implemented by universities worldwide, spanning six categories: transportation, waste management, curriculum, food and dining, water and energy. Each category is clearly related to one or more of the 17 sustainable development goals. A cluster analysis was also applied to identify regional trends in preferred initiatives. Findings: The study underlines the importance of integrating sustainability principles into the curricula of higher education institutions (HEIs) as well as educating staff members on energy and water management. The most common and impactful initiatives in the studied six categories have been identified. Many of the initiatives mentioned in the study do not just result in reducing ecological footprint but also provide economic savings as well. Differences among regions and countries were observed in the implementation of initiatives. Cultural and habitual factors should not be disregarded during the selection process of initiatives. Originality/value: The findings of this study may help universities to take their first steps toward implementing initiatives that can effectively promote sustainable development. Results will aid other HEIs in planning for next steps while outlining the more common initiatives.
