The International Civil Aviation Organization, or ICAO, is a specialized agency of the United Nations that was established to promote the safe and orderly development of international civil aviation. Founded in 1944, ICAO sets global standards and regulations necessary for aviation safety, security, efficiency, and environmental protection. ICAO works with its member states and industry stakeholders to develop policies and guidelines that enhance the safety and efficiency of air transport. It also plays a crucial role in coordinating international efforts to address issues such as air traffic management and environmental sustainability in aviation.
