Thank you for your understanding.
The ICAO Aviation Climate Week 2026, centered around the theme One Global Path: Advancing Net-Zero Aviation, will be held from 26 to 28 May 2026, at the ICAO Headquarters, Montréal, Canada, as an in-person event.
Building on Global Momentum
This key event will build on the momentum of the first edition held in June 2025, establishing this initiative as ICAO’s annual global platform to advance aviation’s environmental and climate agenda.
This three-day event offers the opportunity to learn the latest developments in all aviation environmental topics, including the outcomes of the 42nd Session of the Assembly, and the advent of the ICAO ACT-LTAG programme, as we move towards achieving net-zero carbon emissions by 2050. The event will also allow the monitoring of further progress on the ICAO Global Framework for SAF, LCAF and other Aviation Cleaner Energies adopted at CAAF/3, including the collective global aspirational Vision to reduce CO2 emissions in international aviation by 5 per cent by 2030.
Key Pillars of the 2026 Agenda
Come and be part of the global momentum driving environmental sustainability in aviation and help strengthen collective action across all environmental areas. The 2026 ICAO Aviation Climate Week will:
- Share information on the outcomes of the 42nd ICAO Assembly on international aviation and climate change and set the scene with recent science, academic research, technological innovation, and relevant global developments, as we move towards achieving LTAG of net-zero carbon;
- Overview of the latest research on the climate impact of non-CO2 aviation emissions.
- Present latest progress on LTAG Monitoring and Reporting methodology, including approaches to monitoring, reporting and accounting CO₂ reductions from technology, operations and fuels.
- Showcase cutting-edge advancements in aircraft technology, infrastructure and operations, including next-generation airframe and engine concepts, more stringent CO₂ and noise Standards, emerging aircraft technologies and hydrogen propulsion research, as well as innovations in air traffic management and ground operations that reduce CO₂ emissions.
- Showcase advancements on aviation cleaner energies, with a focus on the ICAO Global Framework for SAF, LCAF and other Aviation Cleaner Energies, providing the latest achievements and experiences under four Building Blocks: policy planning, regulatory framework, implementation support, and financing;
- Encourage action for implementation support, including under the ICAO ACT-SAF programme, its extension to ACT-LTAG, and its linkage with State Action Plans;
- Unlock financing by showcasing the latest efforts on financing aviation decarbonization measures, including progress toward full operationalization of the ICAO Finvest Hub, and discussions on additional financing opportunities for aviation decarbonization projects;
- Celebrate a Decade of Progress by highlighting the latest achievements on CORSIA implementation, including CO₂ emissions monitoring, reporting, verification, use of eligible emissions units, and recognizing 10 years of the scheme and its contribution to aviation’s global climate action;
- Address a broad range of other environmental topics, such as sustainable infrastructure and operations, climate adaptation and resilience, circular economy and waste management, and biodiversity protection;
- Provide a platform for Member States and stakeholders to share innovative initiatives, projects, partnerships and technologies driving the transition to sustainable aviation, and discuss future challenges and opportunities.
Capacity Building: Opportunities under ACT-SAF Programme
The Climate Week will provide a unique opportunity to join the ICAO Assistance, Capacity-building and Training for Sustainable Aviation Fuels (ACT-SAF) programme and create synergies between ACT-SAF Partners. Detailed information on the ACT-SAF programme can be found on the dedicated ACT-SAF public website and additional States and organizations willing to become partners are invited to contact the ICAO Secretariat: officeenv [at] icao.int (officeenv[at]icao[dot]int).
Exhibition & Sponsorship: Showcase Your Impact
During the three-day event, a simultaneous exhibition will be held on-site at ICAO Headquarters. Connect with new partners, showcase your products and solutions, and explore opportunities for joint initiatives and cross-sectoral collaboration.
