CARB to Review Ethanol Carbon Intensity Amendments
by Kris Bevill (Ethanol Producer Magazine) The California Air Resources Board will hold a public hearing Feb. 24 to consider 25 amendments proposed by various ethanol producers, representing 1.6 billion gallons of annual domestic production, to reduce the carbon intensity of their fuel. Fuel pathways are used to determine a fuel’s carbon intensity (CI). The CI of the fuel is then recorded in the state’s CI look-up tables, the reference point used by providers of transportation fuels to demonstrate compliance with California’s Low Carbon Fuel Standard.
