Abstract
This deliverable examines the potential roles that airports can take in supporting the scale-up of Sustainable Aviation Fuels (SAF), based on work carried out in TULIPS Task 5.5 during 2022–2026. The report reviews airport motivations, infrastructure and stakeholder conditions, the evolving European regulatory framework, book-and-claim mechanisms, airport incentive options, examples of best practice, TULIPS workshop findings, and passenger and corporate awareness activities at Amsterdam Schiphol Airport and Avinor Oslo Airport. The aim is to clarify where airports can make a practical contribution, where their role is limited, and which measures appear most relevant under the current regulatory and market conditions.
