The aviation sector plays a vital role in connecting the world, supporting economic development, and enabling global mobility. At the same time, the international aviation community is working collectively to address its environmental impact and advance the transition toward a more sustainable future. From 2 to 4 June 2026, the ICAO Aviation Climate Week 2026 will bring together governments, industry leaders, international organizations, and environmental experts at ICAO Headquarters in Montréal, Canada. The three-day event will serve as a global platform for dialogue, collaboration, and knowledge-sharing on the most pressing environmental challenges and opportunities facing international aviation.
Under the theme “One Global Path: Advancing Net-Zero Aviation,” the event will explore the progress being made across the aviation sector to achieve the Long-Term Global Aspirational Goal (LTAG) of net-zero carbon emissions by 2050.
ICAO Aviation Climate Week provides a unique opportunity for stakeholders from across the aviation ecosystem to exchange ideas, share expertise, and strengthen international cooperation. Through a series of high-level discussions, technical sessions, and networking opportunities, participants will explore innovative solutions and practical strategies to accelerate environmental progress in aviation.
The event will highlight recent developments following the 42nd ICAO Assembly, including the launch of new initiatives supporting States in implementing aviation climate actions. These include the Assistance, Capacity-building and Training for the Long-Term Global Aspirational Goal (ACT-LTAG) programme, which support States in advancing measures that contribute to aviation’s net-zero transition.
Advancing climate solutions across the aviation sector
Discussions during the week will focus on the wide range of solutions needed to address aviation’s environmental impact. These include progress on the Global Framework for Sustainable Aviation Fuels (SAF), Lower Carbon Aviation Fuels (LCAF), and other Aviation Cleaner Energies, which are expected to play an important role in reducing aviation emissions in the coming decades.
Sessions will also explore innovations in aircraft technology, operational improvements, and infrastructure measures that can reduce emissions across the aviation system. Participants will examine emerging research on non-CO₂ aviation emissions, as well as approaches to monitoring and reporting progress toward climate targets.
Together, these discussions will help strengthen the global framework guiding aviation’s environmental transition while supporting practical implementation across all regions.
Ensuring a truly global transition
A central priority of ICAO’s environmental work is ensuring that the transition toward sustainable aviation is inclusive and achievable for all States. Through initiatives that support capacity building, technical cooperation, and knowledge sharing, ICAO continues to help countries implement environmental measures while ensuring that no country is left behind in aviation’s path toward sustainability.
ICAO Aviation Climate Week will reinforce this collaborative approach by bringing together diverse perspectives from governments, industry, academia, and international organizations, ensuring that progress toward net-zero aviation reflects the needs and realities of the global aviation community.
Join the global conversation
As aviation continues to grow and evolve, coordinated international action remains essential to ensuring that the sector can meet future demand while reducing its environmental impact. ICAO Aviation Climate Week 2026 offers a unique opportunity to engage with experts, policymakers, and innovators working at the forefront of aviation climate solutions. Participants will gain insights into the latest developments in sustainable aviation, contribute to discussions shaping global environmental strategies, and help advance the shared vision of a more sustainable aviation future.
