Southwest Airlines has entered into a significant offtake agreement with USA BioEnergy for up to 680 million gallons of neat sustainable aviation fuel (SAF). Over a 20-year term, once blended with conventional jet fuel, this SAF could yield the equivalent of 2.59 billion gallons of net-zero fuel, resulting in a reduction of 30 million metric tons of CO2 emissions.

Agricultural by-products including sugarcane will be turned into jet fuel through investment from the Qantas Group, Airbus and the Queensland Government
