International Civil Aviation Organization

The International Civil Aviation Organization, known as ICAO, is based in Montreal, Canada. It works under the International Civil Aviation Convention. The ICAO Assembly includes 193 States, and the ICAO Council includes 36 States. The organisation brings governments and the aviation sector together through its assemblies, councils and events.

Its strategic goals say that every flight should be safe and secure. They also say that aviation should be environmentally sustainable, and that it should offer accessible and reliable mobility for all. Other goals cover the legal framework of the Convention and the economic development of air transport. A goal called No Country Left Behind focuses on support for all states.

The Secretariat includes an Air Navigation Bureau, an Air Transport Bureau, a Capacity Development and Implementation Bureau, a Legal Affairs and External Relations Bureau and an Administration Bureau. The Secretary General leads the Secretariat. The Air Navigation Commission also sits within the organisation's structure.

Regional offices are in Bangkok, Mexico City, Beijing, Lima, Nairobi, Dakar, Paris and Cairo. Each office has its own contact details. The organisation also runs capacity development and implementation support, and ICAO Training describes courses for aviation professionals.

The environment section covers CORSIA, State Action Plans for aviation CO2 reduction, the ICAO Carbon Calculator and the Finvest Hub. Its resources include environment reports, economic facts and figures, the Air Transport Monthly Monitor and the Global Aviation Safety Plan. Safety reports, safety audit results and the Global Air Navigation Plan are also available.

It runs an ICAO Store for publications and an ICAO E-Library. Its projects include SmartSky, the Safety Information Monitoring System and a Blockchain Sandbox. Partners can express interest in the ICAO Project-based Partnership Opportunities, known as TIPPO, which brings in corporations, foundations and individuals.

Information on the 42nd Session of the Assembly covers the schedule, the Council election, resolutions, working papers and information for delegates. Featured events include the 40th Session of the Legal Committee and the ICAO Green Airports Seminar 2026. Media enquiries go to the media relations team.
