A new study published by the National Academy of Sciences could deliver a death blow to E85 ethanol fuels.
Automakers like General Motors and Ford, along with numerous farm states and agricultural lobbyists have long promoted ethanol as an environmental friendly alternative to gasoline.
But the newly published study suggests the opposite is true, estimating corn-based ethanol actually is at least 24% more carbon-intensive than gasoline. The report could influence future use of biofuels, a subject now under review by the Biden administration.
