Abstract
Sustainable Aviation Fuels (SAF) have been the subject of extensive research for several decades; however, their deployment remains limited, contributing to less than one percent of global aviation fuel consumption. This talk will provide fundamentals of SAF, detailing their production pathways, physicochemical properties, and implications for engine performance and emissions. In addition to evaluating their potential for reducing lifecycle CO₂ emissions, the presentation will address a critical yet underexplored issue: the non-CO₂ climate impacts associated with SAF use, including effects on contrail formation and radiative forcing. By highlighting current scientific understanding as well as key uncertainties, the talk aims to frame the opportunities and limitations of SAF within the broader context of aviation climate mitigation.
