The American Coalition for Ethanol (ACE) has introduced a new carbon intensity (CI) calculator to help its members understand the carbon intensity (CI) of their farms and ethanol operations along with a simplified version of the tool to raise awareness about factors impacting the CI of ethanol. Combined, these tools help illustrate corn ethanol’s ability to attain net-zero and net-negative greenhouse gas emissions.
The topic of carbon intensity can generate confusion because various regulatory bodies (EPA, CARB, etc.) apply different approaches to derive carbon scores. What’s more, some regulatory bodies use outdated lifecycle factors to overstate ethanol’s CI, causing understandable apprehension from producers about new clean fuel policies. ACE’s detailed calculator allows users to break through this confusion by using their own corn farming and ethanol production information to estimate a carbon score and compare it to the Argonne National Laboratory’s GREET model and average scores used by the California Low Carbon Fuel Standard.
“When I first looked at the GREET model’s ‘Midwest average’ carbon intensity for corn production, I immediately saw the potential for rapid reductions with more accurate modeling that reflected actual climate-smart production practices being employed by tens of thousands of farmers across the Midwest,” said Ron Alverson, Calculator Creator, Farmer, Dakota Ethanol and ACE Board Member. “The CI calculator we developed at ACE is a tool for farmers and ethanol producers to see for themselves what their potential is to lower their carbon score.”
“ACE is focused on highlighting how climate-smart farming practices, efficiencies at ethanol plants, and the capture and sequestration of CO2 from facilities puts ethanol on a trajectory to reach both net-zero and net-negative emissions; a trajectory unique to ethanol,” said Brian Jennings, ACE CEO. “The calculator is not only useful for farmers and ethanol producers who want to know their CI score, it also helps ACE highlight the need for farm-level practices to receive carbon benefits in clean fuel markets.”
Join ACE for a walk-through demonstration of how the carbon calculator works at the Fuel Ethanol Workshop in Minneapolis on June 14 from 1:30-3:00 p.m. in room 207A. FEW attendees can also visit the American Coalition for Ethanol booth #1201. RSVP to Katie Muckenhirn to attend the in-person demonstration at the FEW.
