What current U.S. policies affect biofuels production and use?
Congress passed energy legislation, known as the Energy Independence and Security Act of 2007, which raises standards for vehicle fuel economy and mandate that U.S. transportation fuel include 21 billion gallons of advanced biofuels by 2022 and 2 billion gallons as soon as 2012. The legislation further requires that these advanced biofuels must achieve at least a 50% reduction in life-cycle greenhouse gas emissions.
