California ARB considering four new low-carbon fuel pathways; Neste renewable diesel and sugarcane molasses ethanol

March 20, 2013

California Air Resources Board (ARB) staff has posted four new Low Carbon Fuel Standard (LCFS) pathways to the LCFS web site. (Earlier post.) Among the new pathways to be considered is the production of renewable diesel from Australian tallow at Neste Oil’s Singapore plant. Others are sugarcane molasses ethanol from Guatemala; mixed feedstock to biodiesel from Texas; and a new ARB-staff-developed pathway for North American landfill gas.

The Low Carbon Fuel Standard, approved in April 2009, requires that suppliers of transportation fuels meet an average declining standard of carbon intensity (CI) —expressed in grams of CO₂ equivalent per megajoule of fuel energy (g CO₂e/MJ)—that will provide a 10% reduction in greenhouse-gas emissions for all fuels used in California by 2020. The CI of a fuel is determined by the sum of all greenhouse gas emissions associated with the production, transportation, processing and consumption of a fuel (its pathway).
