One of ATAG’s priorities for 2024 was to provide industry coordination and develop a position on the non-CO2 climate impacts of aviation, especially contrails. An ATAG working group was established, which will continue in 2025.
ATAG developed a briefing paper (in collaboration with industry experts and specific input from A4A, AAPA, Airbus, Boeing, CANSO, IATA, Pratt & Whitney, GE Aerospace, United Airlines, American Airlines and SAFRAN) on the challenges and action underway to avoid persistent warming contrail formation. This is available for download from the ATAG corporate website.
An Information Paper was also submitted to the ICAO Air Navigation Conference on Industry considerations of contrail management solutions. This focuses on the questions and uncertainties surrounding contrail mitigation.
