As the world grapples with the pressing need to mitigate climate change, Higher Education Institutions (HEIs) are increasingly scrutinizing their carbon footprints. This paper delves into the complex task of analyzing the carbon footprint calculations of three distinct universities: the American University in Cairo (AUC), the American University in Beirut (AUB), and the University of Cape Town (UCT). The central objective is to ascertain how these carbon footprints can be meaningfully compared, considering multifaceted factors encompassing scope coverage, calculation procedures, conversion methods, and sector-specific nuances. The paper relies on a brief literature review of academic journals and published carbon footprint reports of the selected HEIs to draw the comparative analysis. The quantitative analysis examines the carbon footprint numbers of the three universities and seeks to identify variances, trends, and potential outliers of the emissions data that may influence the overall comparative assessment. The paper zooms in on critical sectors significantly contributing to the universities’ carbon footprints, including the heating, ventilation, and air-conditioning (HVAC) systems, transportation, and energy efficiency measures. Through sector-specific analysis, we gain insights into the areas where each institution excels or faces challenges, further contributing to the comparative framework. Understanding to what extent these institutions can be compared not only aids in benchmarking their sustainability efforts but also informs future strategies for reducing their environmental impact in an increasingly climate-conscious world.
