The International Air Transport Association and the International Civil Aviation Organization are set to deepen cooperation to improve tracking of sustainable aviation fuels, IATA said in a statement on Wednesday.
The move aims to strengthen transparency and support the aviation industry's goal of reaching net-zero carbon emissions by 2050, IATA said.
The agreement will explore how SAF registries and related data can support ICAO's long-term aspirational goal monitoring and reporting framework and the development of fuel accounting systems for international aviation.
ICAO Secretary General Juan Carlos Salazar said greater transparency and cooperation were essential to achieving the agency's net-zero emissions goal for international aviation by 2050.
He said enhanced monitoring of SAF production, distribution and use would strengthen global fuel accounting systems and help ensure climate investments are recognized consistently under ICAO frameworks.
The industry's decarbonization push comes against a backdrop of turmoil in fuel markets.
IATA's head of fuel, Daniel Chereau, said on Wednesday that airlines have been hit hard by soaring jet fuel margins and supply disruptions stemming from the conflict in the Middle East, with some carriers unable to hedge their exposure, Reuters reported.
"Some airlines with more elaborate hedging strategies get a bit of a cushion," he reportedly told the S&P Global Energy Middle East Petroleum and Gas Conference.
Soaring jet fuel refining margins, or crack spreads, added to pressure on the industry. In northwest Europe, jet fuel crack spreads surged to a record above $121 a barrel in March from about $30 before the outbreak of the Iran war in late February, he reportedly said, citing LSEG data.
The Middle East supplies much of the world's jet fuel, but exports have been disrupted by the effective closure of the Strait of Hormuz and attacks on energy infrastructure.
Chereau also reportedly said signs of demand destruction were emerging in aviation, driven largely by flight cancellations and fuel shortages at some airports rather than fuel prices themselves.
He warned such disruptions could become more frequent if the conflict persists, with prolonged instability potentially weighing on passenger demand.
