Renewable fuels firm Aemetis has signed an agreement to supply Australian airline company Qantas with 132M litres (35M) gallons of sustainable aviation fuel (SAF) over seven years, Aemetis announced.

Under the agreement, the blended SAF supplied would comprise 40% SAF and 60% Petroleum Jet A to meet international blending standards, according to the 15 March statement.

The supply agreement with Aemetis was in line with Qantas’ aim to achieve net zero emissions by 2050, Aemetis said.

“Climate change… is a key focus for us as we move through our recovery from the pandemic,” Qantas Group CEO Alan Joyce said. “Operating our aircraft with sustainable aviation fuel is the single biggest thing we can do to directly reduce our emissions.”

Due to be produced by the Aemetis renewable jet/diesel plant currently being built on a former US army ammunition production site in Riverbank, California, SAF deliveries to Qantas were expected to begin in 2025, the company said.

California-headquartered Aemetis is a renewable natural gas, renewable fuel and biochemicals company with a focus on the acquisition, development and commercialisation of technologies to replace petroleum-based products and reduce greenhouse gas emissions.
