The ReFuelEU Aviation aircraft operator reporting template can be used for reporting SAF purchases delivered to union airports. EU ETS and CORSIA reports themselves do not provide sufficient detail for the label, however the data that is monitored for reporting and verification will contain sufficient detail and should be modified by an aircraft operator to comply with the requirements of the FEL. The schedules required will already be produced by an aircraft operator for the purposes of network management in the required SSIM format, and both fuel consumption and traffic data will be collected for revenue and operational management.
