Boeing on Tuesday touted “green diesel,” a form of diesel fuel made from waste vegetable oils and animal fats, as a significant new source of sustainable aviation biofuel that could reduce the aviation industry’s carbon emissions.

The jet maker said about 800 million gallons is produced annually today at refineries in Louisiana, the Netherlands, Finland and Singapore for use largely as truck fuel.

Boeing projects expansion that could supply as much as 1 percent of global commercial jet fuel demand, about 600 million gallons annually.

The wholesale cost – about $3 a gallon with U.S. government incentives – is competitive with petroleum jet fuel.
