Plant-based jet fuel could reduce emissions by 68%

Replacing petroleum-based aviation fuel with sustainable aviation fuel derived from a type of mustard plant can reduce carbon emissions by up to 68%, according to new research from Warnell associate professor Puneet Dwivedi.

Dwivedi led a team that estimated the break-even price and life cycle carbon emissions of sustainable aviation fuel (SAF) derived from oil obtained from Brassica carinata, a non-edible oilseed crop. The study was published in GCB Bioenergy.

“If we can secure feedstock supply and provide suitable economic incentives along the supply chain, we could potentially produce carinata-based SAF in the southern United States,” said Dwivedi. The aviation industry emits 2.5% of all carbon dioxide emissions nationwide and is responsible for 3.5% of global warming. “Carinata-based SAF could help reduce the carbon footprint of the aviation sector while creating economic opportunities and improving the flow of ecosystem services across the southern region.”
