International Civil Aviation Organization (ICAO) Global Implementation Support Symposium (GISS 2026) took place in Marrakech, bringing together 1,450 participants from 101 States to strengthen global aviation systems in accordance with ICAO’s strategic plan for 2050, which includes a commitment to “No Country Left Behind” and envisions air transport for all, with zero fatalities and net zero carbon emissions. Greece was represented by the Hellenic Civil Aviation Governor, Dr. Christos Tsitouras.

Over three days, the Symposium delivered a series of commitments, partnerships, and implementation initiatives aimed at enhancing aviation safety, security, sustainability, and connectivity worldwide, with a strong emphasis on ensuring that all States can effectively implement ICAO Standards and Recommended Practices (SARPs). 

ICAO Council President Toshiyuki Onuma highlighted the importance of universal implementation, noting that “Ensuring that every State has the capacity to implement global aviation standards is essential to the safety and resilience of the entire system.”

ICAO Secretary General Juan Carlos Salazar added, “The outcomes of this Symposium demonstrate what multilateral cooperation looks like when it delivers results. Implementation is the true test of our commitments. What matters now is translating these commitments into measurable progress across all regions.” 

A central milestone of GISS 2026 was the Ministerial Roundtable, which brought together 22 Ministers responsible for civil aviation. Through the Marrakech Call to Action, Ministers reaffirmed their commitment to strengthening governance and institutional capacities, unlocking aviation growth and development through adequate funding and financing of aviation, empowering the next generation of aviation professionals and ensuring collective implementation and accountability. 
The Call to Action reflects a shared commitment to ICAO’s No Country Left Behind strategic goal, ensuring that all States can participate in and benefit from the growth of global aviation.
GISS 2026 served as a platform to translate dialogue into concrete implementation outcomes.
These outcomes reflect a growing alignment between policy commitments and implementation support, enabling States to accelerate progress toward ICAO’s Strategic Goals. 
The outcomes of GISS 2026 also respond to the scale of aviation growth ahead. By 2050, global passenger traffic is expected to increase nearly threefold, while air cargo volumes are projected to grow by more than two and a half times. Much of this growth will occur in emerging and high-potential markets. 

Among notable developments, Hellenic Civil Aviation Authority signed a Project Document launching a Civil Aviation Master Plan conference. ICAO EUR/NAT Regional conference on Civil Aviation Master Planning (CAMP), is planned to be held in Athens on May 5^th and 6^th hosted by HCAA. The ICAO Secretary General, Mr. Juan Carlos Salazar and the HCAA Governor Mr. Christos Tsitouras signed the Memorandum of Understanding between ICAO and HCAA concerning the upcoming CAMP. 

This event constitutes an initiative of significant institutional and strategic importance, as it is expected to bring together senior representatives from civil aviation authorities, Ministries of Transport, international organizations, airports, air navigation service providers, airlines, as well as development banks and financing institutions from the EUR/NAT region.

The workshop focuses on issues of strategic planning, sustainable development, and financing in the aviation sector, and is expected to substantially enhance:

• Greece’s role on the regional aviation map
• Institutional cooperation with ICAO and other international bodies
• Τhe attraction of investment and development interest
• Τhe country’s overall international visibility.
