Aviation offset and decarbonization specialist 4Air (Booth Y111) recently rolled out a new Assure SAF Registry program to provide a digital registry for documenting, tracing, and accounting for the sustainability benefits of sustainable aviation fuel (SAF).

Company president Kennedy Ricci told AIN that the program is designed to help operators navigate through what he called a "messy supply chain." Currently in the pilot phase, the program aims to provide transparency by gathering data from suppliers at all levels. Data includes the feedstock used to produce the SAF, the blend of the fuel, and any sustainability certifications earned or regulatory programs for which the fuel may be eligible. The registry will accommodate both physical and book-and-claim approaches.
