The use of oil obtained from crushing carinata (Brassica carinata) seeds for producing drop-in jet fuel could help in reducing the carbon footprint of the aviation sector. Our suitability model suggests that about 7.12 million metric tons of carinata can be produced in southeastern states using average carinata yield of 2802.70 kg per hectare at 5% composite risk level. We found that 821.84 kg of CO2 equivalent GHGs (greenhouse gases) are released while producing 1,000 liters of carinata-based jet fuel. Total savings in GHG emissions will be 85.9%, 69.8%, and 76.4% relative to 1,000 liters of conventional jet fuel based on the mass, market, and energy allocations, respectively. The estimated production price at bio-refinery gate ($0.85/l) was about 30% higher than the current price of conventional jet fuel ($0.55/l) indicating that an incentive of $0.30/l is needed for promoting the production of carinata-based jet fuel in the southeastern United States.
