Air Transport Bureau

The Air Transport Bureau (click to view the Structure) supports the implementation of the Strategic Objectives of ICAO in particular: Security and Facilitation; Economic Development of Air Transport; and Environmental Protection. This Bureau also contributes towards Safety.

The Bureau works under the direction of the Council, Air Transport Committee, the Committee on Unlawful Interference and the Committee on Joint Support of Air Navigation Services. Secretariat support is provided to the Committee on Aviation Environmental Protection (CAEP), which is a Committee of Council.

Aviation Security and Facilitation 

ICAO plays an essential leadership role in the field of aviation security with the ultimate goal of enhancing civil aviation security worldwide. To this end, its efforts are focused primarily on developing and coordinating an effective global policy and legal framework in response to the evolving threat to civil aviation, conducting audits that identify aviation security shortcomings, and assisting States in implementing security Standards and resolving deficiencies.


In the environmental area, ICAO’s overall objective is to enhance the sustainability of international aviation operations by minimizing aircraft noise and the impact of engine emissions on local air quality and the global climate. In this field, ATB focuses on: quantifying the impact of aviation on the environment through the development of methodologies, tools, models and databases; and establishing policies, standards and recommended practices to address the impact of aviation on the environment through technological, operational and market-based measures.

Economic Development 

The Bureau’s activities in the economic fields are linked to the sustainability of air transport development. In this regard, the Bureau is responsible for developing, promoting and disseminating policies and guidance materials on major regulatory issues linked to the economic regulation and liberalization of international air transport and to the economics of airports and air navigation services. Of paramount importance is the availability of a wide range of reliable and robust aviation data. Towards this purpose, ATB manages the Statistics Programme, the forecasting activities and the economic studies, enabling the provision of authoritative information on present and future air transport development.
In addition to supporting the Strategic Objectives above, ATB administers:
    • the Joint Financing Agreements with Denmark and Iceland for the provision certain North Atlantic air navigation services (DEN/ICE);
    • the Arrangement on the Joint Financing of the North Atlantic Height Monitoring System (HMS);
    • the Agreement on the Sharing of Costs of the Satellite Distribution System for information relating to Air Navigation (SADIS); and
    • the ICAO Public Key Directory is the main global distribution point for public signing key certificates from all issuers of ePassports.
