ICAO Stocktaking Seminar on aviation in-sector CO₂ emissions reductions

31 August - 3 September 2021
ICAO HQ, 999 Robert-Bourassa Boulevard

The 2021 ICAO Stocktaking is the most important global event of the year on the decarbonisation of the aviation sector.

Building on the 2020 ICAO Stocktaking event, which displayed over 100 innovative solutions to unlock current and future CO2 aviation emissions reduction potentials, along with strong commitments and ambitious roadmaps to zero emissions, the 2021 ICAO Stocktaking will provide a forum for the exchange and collection of information and data between all aviation stakeholders, covering the three areas for in-sector reductions: technologies, operations, and Sustainable Aviation Fuels.

During the four-day event aeronautical pioneers, industry leaders, technical experts, researchers, innovators, civil society advocates, and States, will illustrate their concrete and ambitious plans for decarbonizing international aviation. The event will conclude with a policy day, featuring high-level interventions to discuss the link between the post-pandemic green recovery and the future of sustainable aviation.
