Abstract
The California Air Resources Board (CARB) staff on December 3 posted the "carbon-intensity" calculation application from the Valero/Darling International "Diamond Green Diesel" (DGD) joint venture (JV) for producing all-hydrocarbon renewable diesel from waste fats or vegetable oils.
According to the CARB staff recommendation on the JV application for the "low-carbon fuel standard" (LCFS) program, the agency replicated DGD's carbon-intensity values for "renewable diesel" by tapping CARB's version of the well-known "GREET" calculation model for determining life-cycle greenhouse-gas (GHG) impacts of various fuels.
"On the basis of these findings, [CARB] staff recommends that DGD's 'Method-2B' pathways be approved for use in DGD's mixed-feedstock RD [renewable-diesel] plant," according to CARB.
