The 2025 ICAO Climate Week will be held from 2 to 4 June 2025, at the ICAO Headquarters, Montréal, Canada, as a hybrid event with in person and virtual participation.

This three-day event will cover all environmental topics and will provide an opportunity for participants to be inform of the overall progress achieved on ICAO’s environmental activities prior to the 42nd Session of the ICAO Assembly and discuss the latest developments from all relevant stakeholders.

The ICAO Climate Week will include a 2025 ICAO LTAG Stocktaking, providing a response to the 41st Session of the ICAO Assembly request to monitor progress towards the achievement of the collective LTAG for international aviation of net-zero carbon emissions by 2050. It will also focus on the Third Conference on Aviation and Alternative Fuels (CAAF/3) request to monitor the implementation of the ICAO Global Framework on Sustainable Aviation Fuels (SAF), Lower Carbon Aviation Fuels (LCAF) and other aviation cleaner energies, and on the related ICAO Roadmap approved by the Council.
In addition, the implementation of CORSIA and other environmental topics such as non-CO2 aviation emissions, green airports, climate adaptation and infrastructure resilience will be covered.

All stakeholders who wish to take this opportunity for showcasing their initiatives, products and services from around the world are invited to contact businessdevelopment@icao.int to obtain the full list of sponsorship and exhibition opportunities.
