The International Civil Aviation Organization (ICAO) is a United Nations specialized agency that sets global standards and best practices for international aviation to ensure its safe, efficient, secure, and sustainable growth, coordinating policies on air navigation, security, environment, and economic development for its 193 member states. Headquartered in Montreal, Canada, ICAO facilitates cooperation among nations, develops technical standards (SARPs), and supports implementation through audits and assistance, working to align national regulations with global goals like zero fatalities and environmental responsibility.
North Atlantic Treaty Organization is an intergovernmental military alliance between 32 member states—30 in Europe and 2 in North America. Founded in the aftermath of World War II, NATO was established with the signing of the North Atlantic Treaty in 1949.
