NASA-DLR Study Finds Sustainable Aviation Fuel Can Reduce Contrails

Cleaner-burning jet fuels made from sustainable sources can produce 50%-70% fewer ice crystal contrails at cruising altitude, reducing aviation’s impact on the environment, according to research conducted by NASA and the German Aerospace Center (DLR). Ice crystal contrail formations can linger in the upper atmosphere for hours and affect the way Earth is heated and cooled. They produce localized increases in temperature…
