The California Air Resources Board (ARB) is holding two public workshops regarding the Low Carbon Fuel Standard (LCFS) this week – one to discuss general updates to the LCFS regulation, and the second to discuss updates to the indirect land use change (iLUC) values. Stakeholder feedback is being solicited for both workshops.
The board will discuss a proposal to update iLUC values for corn ethanol, sugarcane ethanol, and soy biodiesel, as well as proposed iLUC values for canola biodiesel, sorghum ethanol, and palm biodiesel.
According to a staff concept paper released prior to the meeting, based on recommendations provided by an Expert Working Group, “(p)reliminary results indicate reductions in the iLUC values for soy biodiesel, sugarcane ethanol, and corn ethanol.” The paper states that ARB staff “contracted with experts to refine and improve the iLUC analysis” and as a result “has incorporated significant changes in the estimation of iLUC for biofuels.”
Among the model and data updates that were included in the new estimates are re-estimated energy sector demand and supply elasticity values; improved treatment of corn ethanol co-product (DDGS); improved treatment of soy meal, soy oil, and soy biodiesel; modified structure of the livestock sector;improved method of estimating the productivity of new cropland; adopting a consistent model version and set of model inputs for all biofuel pathways; and revised yield and demand responses to price.
The adjustments will be presented by staff at the iLUC workshop, scheduled for Tuesday, March 11, from 1:00 – 5:00 pm.
