"“Sustainable aviation fuel is not just for sustainability,” says United Airlines CEO Scott Kirby. “I tell everyone [jet fuel is] our biggest cost. It's our most volatile cost. ...and guess what happened?”"
"“SAF not only supports emission reductions and propulsion for aviation, but also strengthens fuel security and reduces exposure to these external shocks,” says Chris Cooper, CEO of sustainable aviation fuel company XCF Global. At its refinery in Reno, XCF can produce SAF using domestic waste feedstocks, turning fuel from a global commodity to a more stable, local one."
"“Still, SAF remains a small portion of airlines' overall fuel usage. United, a leader in terms of SAF usage, has invested in the production of more than 5 billion gall”"
Gasoline prices have risen sharply as conflict in Iran strains global oil supplies, with average U.S. prices increasing more than a dollar per gallon and surpassing $4 for the first time in four years. Jet fuel costs have also climbed, with U.S. airlines spending 56% more on fuel in March than in February. Higher fuel prices are increasing interest in sustainable alternatives such as electric vehicles, framed as both environmental benefits and protection against geopolitical instability. A similar shift is beginning in aviation through sustainable aviation fuels, which are positioned as reducing emissions while strengthening fuel security. However, sustainable aviation fuels still represent a small share of total airline fuel use, and scaling production to meet demand may be difficult.
