CNN —For the first time, a transatlantic flight operated by a commercial airline will be powered by 100% Sustainable Aviation Fuel (SAF) — a type of plane fuel that bears the promise of a much lower climate impact than traditional ones. The flight is the latest in a series of recent tests involving 100% SAF. Days earlier, business jet maker Gulfstream completed what it billed as the world’s first transatlantic flight using 100% SAF. Large twin-engine jets have performed flights using 100% SAF on both engines before, but these flights involved military aircraft. “One flight on 100% alternative fuel isn’t going to change the fact that 99.9% of aviation fuel is fossil fuel and there’s no great option for feedstock (raw materials) that can be scaled up sustainably,” she says.
