"To solve this, the industry developed a solution called Sustainable Aviation Fuel (SAF). Unlike traditional jet fuel made from crude oil, SAF is produced from renewable sources like used cooking oil, agricultural waste, and other plant-based materials. Crucially, it's designed to work with existing aircraft engines, allowing airlines to dramatically reduce their carbon footprint without having to build new planes."
"SAF has quickly become the poster child for sustainable flight, as it cuts an aircraft's lifecycle emissions by up to 80%. However, the way we scale SAF matters just as much as the volumes we achieve. Many of today's biofuels rely on crops grown on arable land, creating direct competition with food production and increasing the risk of deforestation and biodiversity loss."
Businesses increasingly set net-zero goals that require difficult choices and carry hidden trade-offs. Aviation contributes about 2.5% of global CO2 emissions and is hard to decarbonize. The industry developed Sustainable Aviation Fuel (SAF) from renewable sources like used cooking oil, agricultural waste, and plant-based materials to work with existing engines and substantially reduce lifecycle emissions. Scaling SAF can cut emissions by up to 80%, but many biofuels rely on crops grown on arable land. Using arable land for fuel creates competition with food production and raises risks of deforestation and biodiversity loss, undermining sustainability claims.
