Perception of Environmental Sustainability and Its Health Implications: Evidence from Faculty Members in Saudi Universities

Environmental sustainability has become a global priority due to its profound implications for human health. Universities play a pivotal role in advancing sustainability through education, research, and institutional practices. This study investigates faculty awareness, perceptions, and sustainability practices, as well as factors influencing these outcomes. A cross-sectional survey was conducted among 118 faculty members across various disciplines and academic ranks in Saudi universities. A structured self-administered questionnaire assessed three constructs: awareness of environmental sustainability, perceptions of health implications, and sustainability practices. Descriptive statistics were computed for overall scale means and item-level responses. Independent-sample t-tests and one-way ANOVA were used to examine group differences across gender, academic rank, discipline, teaching experience, and formal sustainability training. Chi-square tests assessed associations between demographic variables and training participation. The result shows that the faculty demonstrated high awareness (M = 4.09) and strong perceptions of the environmental–health nexus (M = 4.16). Awareness items ranged from 3.96 to 4.22, while health perception items ranged from 3.87 to 4.34. Sustainability practices were moderately high (M = 3.97), with the highest engagement in pollution reduction and the lowest in energy-saving behaviours. Training emerged as the strongest predictor of sustainability outcomes, with trained faculty scoring significantly higher across all constructs (p < 0.001). Therefore, Saudi university faculty possess strong awareness and positive perceptions of environmental sustainability and its health implications, relating to SDG.
