This notice of data availability provides an opportunity to comment on EPA's analyses of grain sorghum used as a feedstock to produce ethanol under the Renewable Fuel Standard (RFS) program. EPA's analysis shows that ethanol from grain sorghum has estimated lifecycle greenhouse gas (GHG) emission reductions of 32% compared to the baseline petroleum fuel it would replace. This analysis indicates that grain sorghum ethanol qualifies as a conventional renewable fuel under the RFS program. Furthermore, this analysis shows that, when produced via certain pathways that utilize advanced process technologies (e.g., biogas in addition to combined heat and power), grain sorghum ethanol has lifecycle GHG emission reductions of over 50% compared to the baseline petroleum fuel it would replace, and would qualify as an advanced biofuel under RFS.
