The Global Implementation Support Symposium (GISS) is ICAO's flagship annual event focused on implementation assistance and capacity building in international civil aviation. Through high-level dialogue, technical sessions, and partnership agreements, GISS plays a vital role in ICAO's mission to ensure no country is left behind in aviation development. Global aviation leaders secured significant commitments toward sustainable aviation fuel production and enhanced capacity-building mechanisms at the International Civil Aviation Organization's (ICAO) fourth GISS, that was held in Abu Dhabi. The three-day event drew 32 Senior Ministerial Officials and over 1500 attendees from 108 States, setting a new attendance record for GISS events. Greece was represented by the HCAA Governor, Dr. Christos Tsitouras.

The symposium directly advances ICAO's 2026-2050 Strategic Plan, which envisions 'a safe, secure and sustainable international civil aviation system that connects the world for the benefit of all nations and people.' The commitments secured during GISS represent concrete steps toward achieving the Plan's three essential aspirations: net-zero carbon emissions by 2050, zero aviation fatalities, and aviation serving as an integral part of a thriving, connected transport system where no country is left behind. These exceptionally ambitious goals require unprecedented levels of international cooperation and capacity building.

The comprehensive program featured discussions on artificial intelligence in aviation, sustainable fuel development, and implementation support mechanisms, which provided insights of critical importance to shaping the international community’s approach to these topics.

"The record ministerial participation at GISS 2025 demonstrates the growing recognition of aviation’s crucial role in supporting economic and societal development,” said ICAO Council President Salvatore Sciacchitano. “These high-level engagements are essential as we work toward SAF production and financing across all regions.”

Addressing the practical implementation of ICAO’s Strategic Plan, ICAO Secretary General Juan Carlos Salazar noted “Our enhanced focus on implementation support for resource-constrained states is central to our mission. Through products, services, technical assistance programs, and donor engagement we are ensuring that no country is left behind, but also that no people are left behind, in aviation development.”

A highlight of the summit was the launch of the Global Sustainable Aviation Marketplace (GSAM) initiative by the UAE General Civil Aviation Authority and supported by ICAO and Sustainable Aviation Futures. This groundbreaking forum establishes new pathways to scale aviation decarbonization and SAF production worldwide.
