Athens International Airport is Net-Zero, 25 years ahead of Europe’s goal

By Viki Tryfona

The Athens International Airport “Eleftherios Venizelos” has officially become the first airport in Europe to achieve a net-zero carbon footprint for its direct and indirect emissions, completing the ambitious Route 2025 program. This achievement, 25 years ahead of the European target for 2050, marks a historic moment not only for the airport but also for the European aviation sector as a whole.

The official presentation of the initiative brought together political leaders, institutional representatives, and top industry executives, highlighting the key role of Athens Airport in the transition to a sustainable aviation model.

The Journey from 2019 to Today

Route 2025 was first presented in 2019 when Athens International Airport committed to eliminating its carbon footprint by 2025. At that time, the market viewed the commitment with skepticism. Today, six years later, Athens Airport is a case study in comprehensive energy transformation.

The CEO of the airport, Giannis Paraschis, presented the data:

From 2005 to today, CO? emissions have decreased from 65,000 tons to 29,000 tons, despite more than doubling passenger traffic.
No carbon offsetting or certificates of origin are used.
The transition relies solely on real emission reductions.

“Simple carbon neutrality was not enough. We wanted true net-zero, without greenwashing,” he emphasized.

The Three Pillars Leading to Net Zero

Route 2025 is the result of an investment plan worth approximately 70 million euros, of which 44 million euros were incorporated into the RRF (22 million in grants and 22 million in loans through NextGenerationEU). The strategy was based on three main pillars:

1. Comprehensive Electrification of the Airport

Replacing 61 vehicles with electric ones.
A new high-power charging network.

2. Energy Self-Sufficiency through Two Solar Parks

16 MWp in operation since 2023, already covering 45% of energy needs.
35.5 MWp in full operation by September 2025, along with an 82 MWh storage system (BESS).

This is the largest energy self-production project at an airport in Europe, producing a total of 88,000 MWh annually, equivalent to the consumption of 22,000 households.

3. Elimination of Natural Gas and Upgrading of Building Facilities

Replacing all boilers with high-temperature heat pumps and an extensive energy upgrade program.

The Institutional Framework and European Dimensions

The Chairman of the Athens International Airport, Michalis Kefalogiannis, described decarbonization as a “one-way street” and highlighted the challenges related to the high cost of technologies and the availability of SAF (Sustainable Aviation Fuels).

The Minister of Environment and Energy, Stavros Papastavrou, noted that the transition to zero emissions “is not a burden but an opportunity for growth, competitiveness, and technological leadership,” emphasizing the new framework for CO? capture and storage.

From his side, Commissioner Apostolos Tzitzikostas spoke about the importance of green infrastructure in transportation and the enhanced European connectivity in Southeastern Europe, while the Minister of Tourism, Olga Kefalogianni, stressed that tourism in Athens is now evaluated based on international sustainability indicators.

Christos Dimas: “Route 2025 Ensures Energy Autonomy and Enhances Greeces Position”

A central point of the event was the speech by the Minister of Infrastructure and Transport, Christos Dimas, who emphasized the strategic nature of the project:

“Route 2025 transforms the airport into one of the few globally that achieves full energy autonomy from renewable sources produced within its facilities,” he said.

The Minister also stressed that Athens Airport has cultivated a steady culture of environmental transformation for 25 years. “Route 2025 is not just a technical project, but a breakthrough in Greek aeronautical infrastructure and our national vision for sustainable development.”

Summarizing the main aspects of the program, he mentioned:

Production, storage, and self-consumption of energy.
Electrification of the fleet.
Elimination of natural gas through heat pumps.
Real-time digital energy management.

Mr. Dimas linked the project to the broader energy policy of the country, emphasizing that the revised National Energy and Climate Plan (NECP) lays the foundation for rapid renewable energy penetration by 2030.

He also referred to:

The National Action Plan for the modernization of air navigation.
The implementation of the European regulation ReFuelEU Aviation, which mandates gradual SAF use starting in 2025 (2%) and 2030 (6%).

In conclusion, he noted:
“The transition to a low-emission economy is not a burden; it is an opportunity. When utilized with a plan and foresight, it becomes a global example. I congratulate all those who worked to make the Route 2025 vision a reality.”
