Adopting sustainable lifestyle practices has become increasingly important in addressing major environmental challenges such as climate change, pollution, and the depletion of natural resources. College students represent a significant and influential group in society, and their participation in sustainability initiatives can contribute greatly to environmental protection. This study focuses on examining the role of college students in practicing sustainable lifestyle behaviours. These practices include reducing plastic consumption, recycling and proper waste segregation, conserving energy and water, and using environmentally friendly transportation options such as public transport or bicycles. The research aims to understand students’ level of awareness, their attitudes toward sustainability, and the extent to which they incorporate these practices into their daily lives. A survey-based research approach was used to collect data from college students. The responses were analyzed to assess their involvement in sustainable activities. The findings reveal that although students generally demonstrate a growing awareness of environmental sustainability, the degree to which they apply sustainable practices varies. Several factors, including limited facilities, insufficient awareness initiatives, and existing behavioural habits, influence the level of implementation. The study concludes that educational institutions have an important role in promoting sustainability through initiatives such as awareness programs, green campus activities, and environmental education. Encouraging sustainable lifestyle practices among students can contribute significantly to long-term environmental protection and the development of responsible future citizens.
