“…recent studies show that the use of ethanol and biodiesel does not reduce greenhouse gas emissions. For many years, proponents of decarbonization assumed that the burning of biofuels would be “carbon neutral.” The carbon neutral concept assumes that as plants grow they absorb carbon dioxide equal to the amount released when burned. If true, the substitution of ethanol for gasoline would reduce emissions.”
“But a 2011 opinion from the Science Committee of the European Environment Agency pointed out what it called a “serious accounting error.” The carbon neutral concept does not consider vegetation that would naturally grow on land used for biofuel production. Since biofuels are less efficient than gasoline or diesel fuel, they actually emit more CO2 per mile driven than hydrocarbon fuels, when proper accounting is used for carbon sequestered in natural vegetation. Further, a 2011 study for the National Academy of Sciences found that, “…production of ethanol as fuel to displace gasoline is likely to increase such air pollutants as particulate matter, ozone, and sulfur oxides.”
“Ethanol fuel is no bargain… According to the US Department of Agriculture, ethanol fuel remains about 25 percent more expensive than gasoline….”
“Mandates for ethanol vehicle fuel are also boosting food prices.”
