Deep dives
Understanding Sustainable Aviation Fuel
Sustainable Aviation Fuel (SAF) is derived from non-fossil feedstocks, such as waste oils, and can significantly reduce aviation-related carbon emissions. Currently, SAF can be blended with traditional jet fuel up to a maximum of 50%; however, its production is limited and comes with a higher cost. Some airlines are offering passengers the option to purchase flights with cleaner fuel, a step towards making SAF a mainstream choice. To achieve broader adoption, substantial reductions in production costs and increases in supply are essential.
