critically analyze an alternative to fossil fuel propulsion. Today, most carriers in air transportation use jet or turbojet aircraft that burn either pure fossil fuel (Jet A-1) or fossil fuel blended with a small amount of Sustainable Aviation Fuel (SAF). With the goals of CORSIA and the EU ETS in mind, manufacturers are developing alternative propulsion methods/fuels to reduce the carbon footprint of aircraft.
