SEATTLE, WA: December 16, 2015. The Port of Seattle, Alaska Airlines and Boeing want to provide biofuel for all flights out of Seattle's Sea-Tac airport with the airline hoping to begin such operations by 2020.

Sea-Tac, the 13th busiest airport in the U.S. and served by 26 airlines, wants to reduce CO2 emissions 25 percent by 2037.

Fuel Farm Alaska AirlinesAccording to the U.S. Department of energy, using sustainably produced biofuel reduces lifecycle carbon dioxide emissions by 50 to 80 percent compared to conventional petroleum fuel.

The Port of Seattle will manage a $250,000 feasibility study due for completion in 2016 to map the engineering and integration costs of a future biofuel infrastructure. Currently, aviation biofuels are not produced in Washington State and have to be imported by truck, rail or barge.

"Sustainable aviation biofuel will play a critical role in reducing aviation's carbon emissions over the long term," said Sheila Remes, Boeing Commercial Airplanes vice president of Strategy. "Boeing, Washington state's largest employer, is proud to work with our customer Alaska Airlines and the Port of Seattle to power every plane at Sea-Tac with a biofuel blend and lead the way for other airports to do the same."

Joe Sprague, senior vice president of communications and external relations for Alaska Airlines added: "Biofuel offers the greatest way to further reduce our emissions. This study is a critical step in advancing our environmental goals and stimulating aviation biofuel production in the Pacific Northwest."

In 2011 Alaska was the first airline to fly multiple flights using a 20 percent blend of sustainable aviation biofuel made from used cooking oil and waste animal fat. Next year the airline will partner with Gevo, a renewable chemicals and advanced biofuels company, to fly the first commercial flight on alcohol-to-jet fuel.

Boeing has active biofuel projects in the U.S., Australia, Brazil, Canada, China, Europe, Japan, the Middle East, South Africa and Southeast Asia.
