The International Civil Aviation Organization (ICAO) Assembly meets every three years in Montreal to debate and decide on the priorities and work programs for the organization. The 42nd Triennial Assembly runs from 23 September to 3 October 2025.

As an official observer organization to ICAO and the only airline organization permitted to submit papers and provide technical input, the Assembly is an important opportunity for IATA to influence ICAO’s agenda to reflect the priority concerns of our members.

For the 2025 Assembly, IATA has submitted some 14 papers covering diverse areas such as sustainability, safety, operations, and digitization. Below are some highlights of the key papers, blogs, and links to further information.

Key IATA Papers

SAF Production
IATA urges states to review state support for the targets set by the ICAO Conference on Aviation and Alternative fuels (CAAF/3) taking into consideration the price-raising consequences of mandates without the anticipated increase in SAF production.

CORSIA (Carbon Offsetting and Reduction Scheme for International Aviation)
CORSIA was agreed by states at the 39th ICAO Assembly (2016) to be the sole economic measure to address aviation’s global carbon emissions. IATA is asking states to reaffirm their commitment to making CORSIA a success as the only economic measure to manage aviation’s climate impact, and make sufficient CORSIA Eligible Emissions Units (EEUs) available for airlines to be able to fulfil their CORSIA obligations.

Revisions to Aviation Corporate Tax
A revision to Article 8 of the UN’s Model Tax Treaty creates an option to base aviation’s corporate tax on where revenue was sourced as well as the nearly universally used system of taxation in the jurisdiction of its principal place of business. If selected, source-based corporate taxation would generate an enormous additional administrative burden with no additional tax revenue generation unless it results in double taxation.

Consumer Protection
In recent years several governments have been considering and implementing consumer protection regulations for air travelers. In many cases these have deferred from ICAO’s Core Principles on Consumer Protection which support alignment with global standards, respect proportionality, and take into consideration exceptional circumstances of mass disruption.

Radio Frequency Spectrum
As the telecoms industry rolls out 5G and eventually 6G services, demands for increased allocations of radio frequency spectrum are being made. Aviation requires spectrum for many purposes including the critical 4.2-4.4GhZ band for radio altimeters. IATA is calling for states to protect safety critical frequencies used by aviation from interference with “guard bands”, and ensure coordination among telecoms and aviation regulators to ensure safety of flight.

Accident Investigations
ICAO Annex 13 requires that states file a final accident report within a year the accident’s occurrence. When this is not possible, updates must be published. Unfortunately, only 57% of accidents between 2018 and 2023 have a publicly available final accident report. This deprives aviation of a vital source of safety information. IATA is asking states to complete accident reports in line with Annex 13 requirements and in a timely manner.

GNSS Interference
Airlines rely on GNSS-based services for safe navigation. GNSS jamming and spoofing incidents are rising in areas near conflict zones. While redundancies exist to preserve safety of flights, this is an unacceptable risk which must be mitigated. States must ensure better coordination with between military and civil aviation authorities to provide airlines with timely risk information and develop a multi-faceted approach to mitigating risks.

Aircraft Mandates
These are the practical requirements, such as installing new systems, that flow from ICAO Standards and Recommended Practices (SARPs) once adopted by regulators. The current Adopted–Effective–Applicable cycle is lengthy and vulnerable to certification delays, supply‑chain constraints, and global disruptions. States should create a mechanism to set realistic applicability dates for aircraft mandates, with active monitoring and flexibility to adjust timelines if global disruptions occur.

Pilot Age Limits (multi‑pilot international flights)
Under ICAO Annex 1 airline pilots on multi‑pilot international operations must retire at 65. IATA supports lifting the multi‑pilot limit to 67, retaining the existing cockpit safeguard of at least one pilot under 65 and pairing the change with stronger, standardized medical oversight. This reflects longer, healthier careers while keeping safety safeguards in place.
