The study identified two significant obstacles to scaling SAF production. Airlines will need 500-million tonnes (Mt) of SAF to achieve net zero carbon emissions by 2050, as outlined in the IATA Net Zero Roadmaps. Power-to-liquid (PtL): This will be required to reach 500Mt of SAF production annually by 2050. “There is enough potential feedstock from sustainable sources to reach net zero carbon emissions in 2050. The potential to turn SAF feedstock into real SAF production is in the hands of policymakers and business leaders, particularly in the energy sector.
