Sustainability refers to the coordinated efforts and actions taken to conserve the Earth's f inite natural resources, ensuring they remain available for future generations. The dominant post-World War II model of consumption-driven growth led to significant ecological problems. As the negative effects of this approach became a serious threat to the well-being of subsequent generations, the concept of sustainability became critically important. In fact, the continued prosperity of development efforts depends on achieving sustainability. Therefore, sustainability must be understood as a multifaceted issue, encompassing environmental, economic, social, and health-related concerns. The healthcare sector is a vital area for sustainability initiatives because it heavily consumes energy, water, chemicals, and single-use items. Integrating environmentally sound practices into this field is essential for protecting both the environment and public health. This integration is complex, however, as it must be accomplished without diminishing the quality or effectiveness of healthcare services. Both healthcare organizations and their personnel bear significant responsibility in this pursuit. A key strategy for improving the sustainability performance of healthcare facilities is to design and build them as eco-friendly, energy-efficient structures based on resource conservation principles. Moreover, healthcare workers' involvement and understanding of sustainability can be developed through focused professional training and institutional education programs. A notable deficiency in the current literature is the lack of dedicated sustainability courses and practical modules in the core curricula of medical and nursing schools. In conclusion, sustainability is a comprehensive concept requiring an integrated assessment of its environmental, economic, and social components. Consequently, embedding sustainability into the structures of the healthcare sector and its educational groundwork is crucial for current and future success. Progress in this domain has the potential to substantially contribute to global sustainability targets.
