The establishment of a green campus assumes significance in ensuring comfort and elevating the overall quality of life. This study was conducted to ascertain the variability in the questionnaires and delineate the attributes of questions exhibiting high variation in the results. Therefore, constructing the UniSZA Green Campus index based on the acquired weighted values. A total of 420 questionnaires were returned out of 500. Principal Component Analysis was employed to extract distinctive information from the amalgamated dataset. The results of the analysis draw out four factors that were discerned and subsequently interpreted as environmental management (46.65%), environmental infrastructure (12.53%), environmental atmosphere (6.35%), and environmental program (5.39%). In assessing the variation of the UniSZA Green Campus Index, distinct categories were identified, encompassing excellent, good, fair, poor, and bad classifications. This study suggests that the average UniSZA Green Campus index is situated within the second category. Despite the indication of good standing, the university should proactively take steps to ensure that UniSZA aligns with the principles of environmental sustainability in daily practices. The index system can serve as a guide for universities to attain sustainability on their campuses.
