SAFs, derived from various renewable and sustainable sources like agricultural waste, non-food crops, and captured carbon, are chemically similar to conventional jet fuel and can be used in current aircraft without modification. The production process transforms these diverse materials into liquid fuels that power aircraft with considerably lower carbon emissions than fossil-based alternatives.

This chapter examines SAF technologies, the scalability challenges posed by feedstock availability, and the role of regulations and policies in promoting industry growth. It also explores the economic and consumer factors influencing SAF adoption.

Key Insights:

• SAFs have the potential to drastically reduce aviation’s carbon footprint, contingent on scientific breakthroughs, economic factors, and supportive policies.
• The production volume of SAFs currently falls short of the industry’s fuel requirements, highlighting the urgency for expanded development.
• The adoption and sustainability of SAFs will depend on consumer demand and policy frameworks as much as on technological progress.
• The chapter offers an in-depth look at SAFs, outlining the collaborative efforts required to steer aviation towards a more sustainable trajectory.
