The High-level Meeting on the feasibility of a Long-Term Aspirational Goal for international aviation CO2 emissions reductions (HLM-LTAG) is held at ICAO Headquarters in Montréal, Canada, from 19 to 22 July 2022 as a hybrid event with both in-person and online participation. The need for the HLM-LTAG stems from the ICAO Assembly Resolution A40-18, paragraph 9, which requested the Council to explore the feasibility of LTAG, and for the progress of the work to be presented to the 41st Session of the ICAO Assembly. The HLM-LTAG is invited to discuss the CO2 emissions reduction scenarios and options for a long-term aspirational goal, along with the means of implementation and the monitoring of progress, before concluding with recommendations. The Meeting brings together high-level officials from States who will have the authority to make policy commitments, as well as a number of international organizations with direct involvement in aviation and the environment invited as Observers.
