Sustainable Aviation Fuels from Low-Carbon Ethanol Production
Not all of the challenge of reducing transportation-related greenhouse gas (GHG) emissions is found at the end of automobile tailpipes. The aviation sector currently accounts for more than ten percent of U.S. transportation-related GHG emissions. To address this issue, the White House recently announced a Sustainable Aviation Fuel (SAF) Grand Challenge to generate at least 3 billion gallons of SAFs by 2030 and, by 2050, sufficient SAFs to meet 100 percent of U.S. aviation fuel demand, currently projected to be around 35 billion gallons annually. Meanwhile, the International Air Transportation Association (IATA), which represents major global airlines, has committed to net-zero carbon emissions from global air transportation by 2050.
