National Low Carbon Fuel Standard study releases major Technical Analysis and Policy Design reports; providing a scientific basis for policy decisions

Green Car Congress

Set a target of reducing the carbon intensity of gasoline and diesel by 10 to 15 percent by 2030. Create separate fuel pools for gasoline and diesel. Although electricity, hydrogen, and natural gas currently account for less than 1 percent of total transportation fuel use in the United States, their use will be expanding.
