Iowa GOP Hopeful Wants Higher Ethanol Mandate

By Timothy Cama

Iowa Republican Senate candidate Joni Ernst asked the Environmental Protection Agency (EPA) Tuesday to increase the amount of ethanol and biodiesel refiners must use, a day after she was accused of not supporting the mandate that is popular among Iowa farmers.

The EPA has proposed to reduce the volume of ethanol that must be blended into gasoline this year, while keeping the biodiesel mandate the same under the Renewable Fuel Standard (RFS).

“As you know, the RFS ensures our national fuel supply provides increased consumer choice, less dependence on foreign oil, improves the environment, and creates jobs for those in my home state of Iowa — and across the country,” Ernst wrote to EPA head Gina McCarthy.

Ernst’s letter came a day after progressive group Americans United for Change launched an advertising campaign accusing her of being close with the oil industry and not supporting the RFS. She will be the subject of a fundraiser this week that includes representatives from the political action committee of Exxon Mobil Corp., which wants the RFS eliminated.

Renewable fuels enjoy strong support in Iowa due to the prominence of the agriculture there.

Evolution of Beef Cattle Farming

Video: Evolution of Beef Cattle Farming

The Clear Conversations podcast took to the road for a special episode recorded in Nashville during CattleCon, bringing listeners straight into the heart of the cattle industry. Host Tracy Sellers welcomed rancher Steve Wooten of Beatty Canyon Ranch in Colorado for a wide-ranging discussion that blended family history and sustainability, particularly as it relates to the future of beef production.

Sustainability emerged as a central theme of the conversation, a word that Wooten acknowledges can mean very different things depending on who you ask. For him, sustainability starts with the soil. Healthy soil produces healthy grass, which supports efficient cattle capable of producing year after year with minimal external inputs. It’s an approach that equally considers vegetation, animal efficiency, and long-term profitability.

That philosophy aligned naturally with Wooten’s involvement in the U.S. Roundtable for Sustainable Beef, where he served as a representative for the Colorado Cattlemen’s Association. The roundtable brings together the entire beef supply chain—from producers to retailers—along with universities, NGOs, and allied industries. Its goal is not regulation, Wooten emphasized, but collaboration, shared learning, and continuous improvement.
