*      Based on 40% oil content of seed and applying ICAO Rule of Thumb Assumptions of SAF HEFA yield from Soybean.

**    Based on 25% removal of agriculture residue, leaving 75% to maintain yields and soil fertility.

***  Calculations of forest residue per acre are based on the conversion of the average availability from 26 dry metric tons/ha, with the 

unit conversions of 1 hectare to 2.47105 acres. It is assumed that 70% of the forest residue can be sustainably extracted for bioenergy purposes, while the remaining 30% is left to ensure soil rejuvenation.

**** For every tonne of dry switchgrass processed, 0.13 t of FT product is produced, of which 0.768 t is SAF. Thus, SAF yield from 

switchgrass is approximately 0.09984 t (or 99.84 kg) per tonne of dry switchgrass.

?      Based on ethanol without our own conversion to SAF.

‡      Although the U.S. is used as a reference for land mass, most of the U.S. has an unsuitable climate for oil palm production. 

§      Applying ICAO Rule of Thumb Assumptions of SAF HEFA yield from Soybean.

¤      Algae-based feedstock is currently at an early stage of development and has not yet undergone comprehensive real-world application trials. Despite its inherent potential as a sustainable fuel source, the effectiveness and scalability of algae for SAFs require empirical validation in practical settings.
