Missouri corn farmers upset by biofuel model

By Blake Jackson

Corn producers in Missouri are fuming over a recent decision by the U.S. Department of Treasury. The issue? A modified version of a model used to calculate biofuel emissions, which could limit their participation in the sustainable aviation fuel (SAF) market.

The Inflation Reduction Act offers tax credits to biofuels that significantly reduce greenhouse gas emissions. Here's the problem for corn growers:

• The Department of Treasury tweaked the GREET model, used to assess emissions, in a way that corn producers see as unfair. They argue the changes make it harder for corn-based ethanol to qualify for the tax credits.
• The new model sets strict requirements for corn production practices to qualify for the tax credit. These include no-till farming, specific fertilizers, and cover crops. Missouri Corn Growers Association (MCGA) President Brent Hoerr argues these practices aren't suitable for all regions due to variations in soil and climate.
• MCGA feels the model overlooks the sustainability efforts already undertaken by corn farmers. They believe farmers should have the flexibility to choose the practices that work best for their land.
• The MCGA is pushing for a greater voice in shaping future biofuel regulations, particularly the 45Z clean fuel production tax credit. They want to ensure corn farmers have a fair shot at participating in the SAF market while maintaining control over their farming practices and data.

In simpler terms, Missouri corn growers worry a new government model might unfairly restrict their ability to contribute to cleaner aviation fuels. They're advocating for a more flexible approach that acknowledges regional differences and existing efforts towards sustainability.
