SAF Lowers Contrail Formation by Up to 70%, Says NASA
Research says aircraft burning a 50/50 sustainable aviation fuel (SAF) blend produce 50 to 70 percent fewer ice crystal contrails at cruising altitude.
Using a 50/50 sustainable fuel blend can reduce contrail formation at cruise altitudes by 50 to 70 percent, according to in-flight research conducted by NASA and Germany's DLR. (Photo: NASA)
