Rather than assuming that producing and using biofuels was carbon-neutral, we explicitly compared the amount of CO2 absorbed on cropland to the quantity emitted during biofuel production and consumption.
Existing crop growth already takes large amounts of CO2 out of the atmosphere.
It turns out that once all the emissions associated with growing feedstock crops and manufacturing biofuel are factored in, biofuels actually increase CO2 emissions rather than reducing them.
Biofuel boom, climate blunder Federal and state policies have subsidized corn ethanol since the 1970s, but biofuels gained support as a tool for promoting energy independence and reducing oil imports after the Sept. In 2005, Congress enacted the Renewable Fuel Standard, which required fuel refiners to blend 7.5 billion gallons of ethanol into gasoline by 2012. renewable fuel consumption, which rose from 4.1 billion gallons in 2005 to 15.4 billion gallons in 2015.
