Liège Airport achieves Level 4, aligning its carbon management ambitions with global climate goals

May 13, 2025

Liège Airport has taken a major step forward in its carbon reduction journey by upgrading to Level 4 of the Airport Carbon Accreditation programme. This achievement builds on more than a decade of climate action and reflects the airport’s deep commitment to aligning its operations with the goals of the Paris Agreement

Having first joined the programme in 2010 and reached Level 2 by 2018, Liège Airport has steadily advanced its carbon management practices. The airport’s ongoing actions include the large-scale electrification of its vehicle fleet, energy optimisation of its buildings, and a transition to LED lighting, which alone saves 460,000 kWh of electricity annually. On the heating side, Liège Airport has achieved further savings of 1.58 million kWh of gas per year.

As part of its collaborative approach to decarbonisation, Liège Airport has also developed a Stakeholder Engagement Plan in partnership with major actors on the airport platform. This joint roadmap outlines concrete steps to reduce emissions across the entire site, from transport and infrastructure to operations.

The airport’s sustainability commitments reflect a long-term vision: to reduce relative CO₂ emissions by at least 75% by 2030 and 85% by 2040 (based on 2017 levels), with the ambition to reach zero emissions by 2050 without relying on offsets. The airport is also actively contributing to the wider transformation of the aviation sector, championing a shift towards global CO₂ neutrality.

Laurent Jossart, CEO of Liège Airport commneted: “We are proud of this long-term collaboration with our partner-operators at the airport. We remain determined to continue our efforts to decarbonise and green airport activities, by promoting a collective and mutually beneficial approach.”
