The 41st ICAO Assembly adopted a long-term global aspirational goal (LTAG) for international aviation of net-zero carbon emissions by 2050 in support of the UNFCCC Paris Agreement's temperature goal. This is a historic agreement that reinforces the leadership of ICAO on issues relating to international aviation and climate change. The adopted Resolution A41-21 is avaialble here.
The LTAG does not attribute specific obligations or commitments in the form of emissions reduction goals to individual States. Instead, it recognizes that each State's special circumstances and respective capabilities (e.g., the level of development, maturity of aviation markets, sustainable growth of its international aviation, just transition, and national priorities of air transport development) will inform the ability of each State to contribute to the LTAG within its own national timeframe. Each State will contribute to achieving the goal in a socially, economically and environmentally sustainable manner and in accordance with its national circumstances.

The LTAG Report present the background, methodologies, results and interpretations of the LTAG feasibility study developed by the ICAO CAEP. For transparency and comprehensiveness, a set of Appendixes is also available to provide more detailed information on modelling approaches, methodologies, models, assumptions, and the results.
The LTAG report is now available, in all the 6 ICAO Languages.
In addition to the LTAG Report, data developed by ICAO CAEP, as provided in the LTAG report, is available to support States that wish to their own analysis, noting that any additional analysis carried out by States will not be considered as part of the CAEP's work.
A compilation of the questions and answers exchanged, both verbally and in written format, during the first day of the five regional 2022 ICAO LTAG GLADs sessions has been published here.
