For the past three decades, sustainable development (SD) at higher education institutions (HEIs) has been receiving increasing global attention based on the recognition of their vital roles in fostering sustainability teaching and practices on their campuses and influencing the larger society to embrace sustainable behaviors. As one of its key dimensions, an institutional framework is a fundamental step and indicator of commitment to advancing SD at universities. However, some universities, especially in the countries of the Global South, are either missing this dimension or have inefficient institutional frameworks due to the lack of standard practice or guidance. This study assesses the extent of establishing an institutional framework for SD in Saudi Arabian universities (n = 44). Data were from a desk study and a survey of university websites and analyzed using content analysis and descriptive statistics. The study found that 72.7% of the universities have shown a commitment to campus sustainability by having sustainability visions; 52.3% have established a dedicated office for SD governance, 68.2% are involved in community outreach and 63.6% collaborate with external agencies in SD efforts. Although there is no evidence of specific campus sustainability plans in the universities, 45.5% of them have SD coverage in their campus development plans or strategic plans. Sustainability assessment and reporting are generally lacking. The findings can improve our understanding of the extent of the commitment of the universities to SD and how they communicate their SD efforts through their websites, which can foster engagement in campus sustainability. The study concludes that a sound institutional framework is vital to implementing SD at universities.
