Unsustainable environmental practices persist. This study verifies the relationships among sustainable practices, environmental awareness, and students’ attitudes. Predictive design, stratified random sampling, survey technique, and regression analysis were utilized. Data from 300 college students showed that environmental awareness and attitudes significantly predicted sustainable practices, explaining 81.2% of the variance, with environmental attitudes emerging as the stronger predictor. This result supports qualitative perspectives to account for the remaining 18.8% of the variance and identify additional factors influencing sustainable practices.
