Airlines Move to Secure Scarce Sustainable Fuel
Updated: Apr 19
IAG, Southwest, and DHL Express struck deals to buy more low-emission fuel, which remains scarce and expensive. Separately, airlines including Amazon’s air-cargo unit Amazon Air, JetBlue Airways, and United Airlines Holdings Inc. joined an industry group aiming to boost the use of sustainable aviation fuel.
About 2% of global emissions come from air travel. Biofuel-based sustainable aviation fuel can cut emissions by up to 80% compared with conventional jet fuel, but it powers less than 1% of flights today.
Sustainable aviation fuel remains scarce and expensive because of a limited supply of raw materials such as waste, crops, or wood that don’t cause deforestation or divert land from food production.
