The company powered its ecoDemonstrator 787 flight test airplane on December 2 with a blend of 15 per cent green diesel and 85 per cent petroleum jet fuel in the left engine.
"Green diesel offers a tremendous opportunity to make sustainable aviation biofuel more available and more affordable for our customers," said Julie Felgar, managing director of Environmental Strategy and Integration, Boeing Commercial Airplanes.
"We will provide data from several ecoDemonstrator flights to support efforts to approve this fuel for commercial aviation and help meet our industry's environmental goals," Felgar said in a statement.
Green diesel is chemically distinct and a different fuel product than "biodiesel," which also is used in ground transportation.

With production capacity of 800 million gallons (3 billion litres) in the US, Europe and Asia, green diesel could rapidly supply as much as 1 per cent of global jet fuel demand.
"The airplane performed as designed with the green diesel blend, just as it does with conventional jet fuel," said Capt Mike Carriker, Chief Pilot for New Airplane Product Development, Boeing Test and Evaluation.
The flight test was coordinated with the US Federal Aviation Administration, Rolls-Royce and Pratt & Whitney, and EPIC Aviation blended the fuel.
