California ARB biofuel carbon intensity data for LCFS
Source : greencarcongress.com
The California Air Resources Board (ARB) staff has updated carbon intensities (CIs) and other information about registered biorefineries, and posted the information at the Low Carbon Fuel Standard (LCFS) biorefinery-registration webpage. (Earlier post.) The vast majority of the data is for ethanol, produced via different pathways. The current CI values highlight the ranges of outcomes from these pathways, with CI values as high as 121.0 g CO2e/MJ for Midwest corn ethanol in a wet mill using coal to 56.6 g CO2e/MJ for a Midwest dry mill using 25% wheat, slurry, sorghum and corn, with natural gas and wet DGS. The LCFS requires the reduction of the carbon intensity of transportation fuels used in California by an average of 10% by the year 2020. Carbon intensity is a measure of the GHG emissions associated with the combination of all of the steps in the lifecycle of a transportation fuel. While carbon intensity (CI) standards are not applicable in 2010 (the first year of the regulation), compliance with the reporting and record keeping requirements is required for all years, including 2010.
