Pressure on airlines to find petroleum alternatives is taking off, particularly following the agreements reached at the just-completed Climate Change Summit in Paris, the Puget Sound Business Journal reported.

Boeing Co. is working with Alaska Airlines in an initiative to make Seattle-Tacoma International Airport the first airport to regularly offer biofuel to airlines.

The Port of Seattle on Wednesday signed an agreement with the two companies for a $250,000 study to determine how biofuel can be provided at the airport and delivered to aircraft. The funds are all from the port, with Alaska Airlines and Boeing providing expertise for the study.

“As leaders in aviation biofuels, this will send a signal to airlines and biofuel producers that Sea-Tac Airport will be ready to integrate commercial-scale use of aviation biofuels,” said Port of Seattle Commissioner John Creighton in a statement. He has been pressing all year for Sea-Tac to become a leader in the new technology.
