San Francisco International Airport (SFO) in the US has signed a memorandum of understanding (MoU) with a group of eight airlines and fuel producers with regard to the use of Sustainable Aviation Fuels (SAF) aimed at reducing greenhouse gas emissions.

All of the concerned partners including suppliers, airlines and airport agencies will collaborate on expanding the use of SAF at the airport.

San Francisco International Airport director Ivar Satero said: “SFO is an industry leader in sustainability, and we are proud to be the first airport to sign a truly holistic agreement on the use of Sustainable Aviation Fuels.

“By including the entire supply chain process, from producer to end user, this agreement has the power to drive a truly meaningful reduction in aviation-related greenhouse gas emissions. I appreciate the commitment of the airlines, fuel providers, and fuel consortium that came together for this historic agreement.”

“This agreement has the power to drive a truly meaningful reduction in aviation-related greenhouse gas emissions.”

The United Airlines, Alaska Airlines, American Airlines, and Cathay Pacific represent approximately 70% of all flights at the airport.

The four fuel producers include Chevron and Shell, SFO’s two primary suppliers, along with Neste and LanzaTech.

Together with the airport’s fuel consortium SFO Fuel, the partners will continue to actively strive to increase SAF supply globally and at San Francisco International Airport.

The airport is currently working on a study to identify the necessary supply chain and infrastructure required to make the SAF expansion a reality and is also preparing an implementation plan.

At present, airlines at SFO consume more than one billion gallons of jet fuel per year.

SFO, which offers non-stop flights to more than 49 international cities on 43 international carriers, connects non-stop with 85 cities in the US on 12 domestic airlines.
