Universities possess a unique capacity to influence a more sustainable future through both educational content and operational practices. This study examines how students at Cypriot universities experience, perceive, and engage with environmental sustainability and energy efficiency on their campuses. To gain insight into student perspectives, a survey was conducted with 149 students from five public and private higher education institutions, assessing their awareness of and attitudes toward campus sustainability and energy-saving initiatives. Our findings reveal that while students care deeply about environmental issues and support the idea of greener campuses, many are not fully aware of the sustainability efforts, energy management systems, or environmental strategies that their universities have already put in place. Limited communication and the low visibility of these initiatives seem to make it harder for students to get involved or participate meaningfully. Based on the survey, it is evidenced that universities can foster a stronger culture of sustainability by making their efforts more visible, improving communication, and actively involving students in projects around campus. Integrating sustainability into courses, encouraging hands-on participation, and introducing practical tools like real-time energy monitoring could help students develop more environmentally responsible habits.
