Sustainability in higher education (HE) is increasingly critical for preparing future leaders to address environ-mental, social, and economic challenges. While global sustainability ranking systems provide frameworks for assessing university performance, they often rely on self-reported data, raising concerns about their accuracy and relevance to actual stakeholder experiences. This study proposes a stakeholder-centric framework for assessing university sustainability that emphasizes indicators measurable directly by students, faculty, staff, and alumni. The research begins with an in-depth comparative analysis of leading global ranking systems to identify core sustainability performance indicators. These indicators were then evaluated based on their measurability from the stakeholder perspective. The outcome is a comprehensive, easy-to-use scorecard that includes only those indicators with high stakeholder observability and alignment across multiple ranking systems. Such an approach provides a more realistic yet empirical assessment of sustainability in HE since stakeholder perceptions are taken as the key performance indicator.
