septembre 28, 2026

Libreville Léon Mba International Airport in Gabon has reached Level 4+ of Airport Carbon Accreditation, strengthening its work to reduce emissions across its operations and engage stakeholders across the wider airport ecosystem. The achievement makes Libreville the third airport in the African region to reach Level 4+.

Operated by GSEZ Airport, Libreville Léon Mba International Airport has a long standing commitment to carbon management. The airport first joined Airport Carbon Accreditation at Level 1 in 2015, making it one of the first airports in Africa to participate in the programme. It has since progressed through the levels, reflecting continued efforts to strengthen its carbon management and reduce its environmental footprint.

The airport’s progression to Level 4+ builds on a structured approach focused on reducing its carbon footprint, improving the energy and operational efficiency of its facilities and engaging the wider airport community in decarbonisation.

A key focus has been the monitoring and control of energy consumption, enabling the airport to identify its main sources of emissions and implement targeted measures to improve efficiency. GSEZ Airport is also working to improve the energy performance of its infrastructure by optimising equipment and installations, while progressively exploring cleaner and more efficient solutions for vehicles, equipment and other assets used across its operations.

Recognising that airport decarbonisation requires action across the wider airport community, GSEZ Airport is also working with airlines, ground handling companies, service providers, suppliers, authorities and other partners operating at the airport. This engagement supports coordinated action and encourages emissions reductions beyond the airport operator’s direct control.

Commenting on the achievement, Igor Simard, Director General of Libreville Léon Mba International Airport, said: “Achieving Level 4+ of Airport Carbon Accreditation marks a major milestone in our commitment to a more sustainable and responsible aviation sector. This international recognition is the result of a collective effort, a continuous commitment to improvement and the mobilisation of our teams and partners. It reflects our ambition to make Libreville Léon Mba International Airport a leading airport platform in Africa, combining operational excellence, environmental performance and sustainable development. We are proud of this achievement and determined to continue our efforts to reduce our carbon footprint and contribute to the environmental transition of the aviation sector.”

Ali Tounsi, Secretary General of ACI Africa, said: “Achieving Level 4+ of Airport Carbon Accreditation is a significant milestone for Libreville Léon Mba International Airport. It reflects a strong commitment to climate action and places the airport among a select group worldwide demonstrating advanced carbon management. We warmly congratulate the entire team and are proud to welcome another African airport into this group.”

The achievement of Level 4+ marks another step in Libreville Léon Mba International Airport’s carbon management journey. From being among the first African airports to join Airport Carbon Accreditation in 2015 to becoming the third airport in the region to reach Level 4+, Libreville demonstrates the value of sustained carbon management and collaboration in advancing airport decarbonisation.
