The Athens International Airport (AIA) achieved Net Zero status in 2025 — 25 years ahead of the aviation industry’s 2050 target. This was made possible by the completion of its ambitious Route 2025 decarbonisation programme, launched in 2019.
Backed by a €70 million investment from EU Recovery and Resilience and NextGenerationEU funds, the programme prioritised eliminating direct emissions over relying on offsets. AIA now generates all of its electricity on-site from renewable sources, primarily through two photovoltaic parks with a combined capacity of 51.5 MWp. These parks are supported by an 82 MWh battery storage system that enables full energy self-consumption.
Other measures included electrifying the airport’s vehicle fleet, replacing natural gas boilers with high-temperature heat pumps and installing digital energy management systems.
AIA’s successful early decarbonisation efforts symbolise green growth, innovation and sustainable tourism, paving the way towards a more environmentally friendly future.
