Kenya Airways has become the first African airline to use sustainable aviation fuel (SAF) provided by Eni for a long-haul flight. The airline mixed Eni Biojet, which contains 100% biogenic feedstock and is suitable for use with up to 50% of JetA1 fuel, with conventional jet fuel for the flight from Nairobi to Amsterdam. The initiative is part of the Sustainable Flight Challenge, a friendly competition between SkyTeam member airlines. All aircraft departing from European airports will be required to incorporate a proportion of SAF from 2025. Eni and Kenya Airways are working on a broader agreement for long-term collaboration.
