Belfast International Airport has achieved Level 3 ‘Optimisation’ in the Airport Carbon Accreditation (ACA) scheme. 

This Level 3 ‘Optimisation’ achievement signifies that Belfast International Airport has successfully engaged its third parties, including airlines and various service providers, in carbon footprint management. This includes working with partners to understand and reduce emissions across the airport’s supply chain. In line with VINCI Airports' environmental strategy, this initiative is part of the airport's ongoing commitment to sustainable operations, which includes a range of measures such as energy efficiency improvements, the introduction of electric vehicles across the airport fleet as vehicles as well as all diesel vehicles operating fuelled by Hydrotreated Vegetable Oil, (HVO) and the development of a comprehensive sustainability strategy. This initiative aligns with VINCI Airports’ global commitment to achieving net zero emissions by 2050.
