Sustainability became the key priority for the whole world, governments, leaderships and health care organizations, aiming at optimizing the resources efficiently and being recognized in the community. Aim of Work: The aim of this review article is to provide and explore the research landscape in the field of green hospitals and highlight sustainable practices within the healthcare sector. Renewable energy integration, innovative practices, smart building management systems, benefits and challenges in implementing of sustainability practices will be explored. Green hospital certification requirements involve assessing healthcare facilities with specific environmental sustainability standards and practices that minimize resource consumption, lower carbon foot print along with maintaining high-quality patient care and staff satisfaction. In conclusion, adopting sustainability approaches and practices in health care facilities is essential for enhancing public health through reduction of environmental negative impacts, improving health outcomes, promote cost effectiveness, mitigate climatic changes, engage community and pose hospitals as leaders in health sector transformation.
