Fuel accounts for the vast majority of the aviation sector's emissions. Generally produced from sustainable resources, like waste oils and agricultural residues, SAF is seen as one of the key tools to help decarbonize the aviation industry in the near- to medium-term. SAF producers estimate the fuels can result in lifecycle GHG emissions reductions of as much as 85% relative to conventional fuels. According to the companies, the evolution of the platform comes as SAF represents the most viable current solutions to reduce aviation emissions, yet SAF is still only produced in relatively small quantities, with the IATA recently estimating that SAF production in 2025 will account for just 0.7% of airlines' total fuel consumption. Efforts to meaningfully increase the use of SAF by airlines face significant challenges, including the low supply currently available on the market, and prices currently well above those of conventional fossil-based fuels.
