Wisconsin corn farmers upset by SAF limits

By Blake Jackson

Wisconsin corn producers are expressing disappointment over a recent decision by the U.S. Department of Treasury. The decision restricts the use of corn-based ethanol in sustainable aviation fuel (SAF), a biofuel touted for its potential to reduce greenhouse gas emissions in the aviation industry.

The issue stems from new limitations placed on how corn ethanol can qualify for tax credits under the Inflation Reduction Act (IRA). These tax credits are intended to incentivize the production of biofuels that significantly reduce emissions.

Here's what's causing the concern:

• Updated Emissions Model: The Department of Energy's Argonne GREET model, used to assess biofuel emissions, now factors in land-use changes associated with corn production. Corn growers argue these adjustments unfairly penalize corn ethanol's carbon footprint.
• Impractical Requirements: The updated model requires corn used in SAF production to be grown using specific conservation practices, including no-till farming, advanced fertilizers, and cover crops. Farmers argue these practices aren't feasible for all corn-growing regions due to variations in land and climate.

James Giese, president of the Wisconsin Corn Grower Association, emphasizes that Wisconsin farmers already implement sustainable practices tailored to their land's specific needs. He fears the new requirements might hinder opportunities for corn ethanol in the SAF market.

The National Corn Growers Association (NCGA) echoes these concerns. NCGA president Harold Wolle expresses frustration that the model disregards the practicality of implementing uniform practices across diverse corn-growing regions. He emphasizes the potential of high-blend corn ethanol to contribute to the fight against climate change.

The IRA established tax credits for biofuels demonstrating at least a 50% reduction in greenhouse gas emissions compared to traditional jet fuel. Corn growers advocated for ethanol's inclusion, but recent developments raise questions about the Biden administration's commitment to ethanol as a climate solution within the aviation sector.

Wisconsin corn farmers, along with national organizations, are urging a revision of the GREET model to ensure a fair evaluation of corn ethanol's role in sustainable aviation fuel production.
