Hospitals are among the institutions that consume large amounts of energy and resources due to the nature of their healthcare services, which require medical equipment and devices to operate around the clock, in addition to substantial consumption of water and electricity and their reliance on transportation, supply chains, and logistical services. With growing global attention to mitigating the impacts of climate change, implementing environmental sustainability principles in the healthcare sector has become an important approach to reducing hospitals’ carbon footprints, while also improving operational efficiency and enhancing the quality of healthcare services. One of the key steps toward achieving sustainability in hospitals is the transition to renewable energy sources, such as solar energy, along with adopting more energy-efficient systems, including smart lighting and high-efficiency heating, ventilation, and air-conditioning systems. These measures can reduce energy consumption and the resulting emissions, while also lowering operating costs over the long term. Digital transformation represents another important pathway for supporting healthcare sustainability through the adoption of electronic medical records, digital platforms for communication and information exchange, and telehealth services when appropriate. These practices help reduce paper and printing use, limit unnecessary travel by patients and healthcare staff, and consequently reduce part of the emissions associated with transportation and administrative processes. Sustainable resource management is a fundamental component of reducing the environmental impact of hospitals. This can be achieved by improving the procurement and supply of medicines and medical supplies and organizing delivery schedules to minimize unnecessary trips. It also includes using smart systems to monitor energy and water consumption, identify areas of waste, and address them effectively. Proper management, segregation, and recycling of medical waste, in accordance with health and environmental regulations, are also important steps toward reducing the environmental impact of the healthcare sector. Sustainability is not limited to technology and infrastructure; it also involves building an environmental culture within healthcare institutions. This can be achieved by raising awareness among physicians, nursing staff, administrative personnel, and other employees about the importance of conserving energy and water, minimizing waste, and promoting appropriate reuse and recycling practices. Involving staff in these practices helps transform sustainability from a set of separate measures into an integral part of the hospital’s daily work culture. Accordingly, integrating sustainability principles into healthcare institutions represents a long-term investment that combines environmental protection, improved economic efficiency, and enhanced public health. A sustainable hospital not only contributes to reducing carbon emissions and resource consumption but also strengthens its ability to provide safe and effective healthcare, demonstrates its responsibility toward society and the environment, and aligns with modern efforts to build more resilient and sustainable healthcare systems.
