New Studies: The Environmental Benefits of Corn Ethanol

In formal comments submitted to the Environmental Protection Agency (EPA), Growth Energy urged the agency to finalize robust renewable volume obligations (RVOs) under the Renewable Fuel Standard (RFS) for 2023-2025. Growth Energy backed its comments with two new studies reaffirming the need for EPA to accurately model bioethanol’s climate benefits and reject unsupported claims that attempt to diminish bioethanol’s significant environmental benefits.

The research submitted by Growth Energy includes a report from Ramboll, building on previous research submitted in 2019 that debunks much of the flawed science concerning biofuels’ effect on land use change and other environmental impacts, including under the Endangered Species Act (ESA). The study adds to the wealth of public and private data demonstrating that the RFS remains “unlikely to result in material land conversion” or other impacts requiring further ESA reviews. A few key points from the study include:

  • There is no evidence of a causal link between the Renewable Fuel Standard (RFS) and land use change (LUC).
  • There is no credible evidence that the proposed RVO standards will adversely affect wetlands, ecosystems, wildlife habitat, or water quality.
  • Modeling indicates that the statistical dependency between the implied conventional volume and corn prices is non-existent to very weak.

Growth Energy also submitted a report conducted by Environmental, Health and Engineering, Inc. which further highlights the important additional environmental and public health benefits of higher ethanol blends and adds to the literature knocking down flawed science on land use change.

We’ll NEVER Use These Grain Bins Again!

Video: We’ll NEVER Use These Grain Bins Again!


A huge change is happening on the farm — our new grain bin has officially arrived, and that means we’ll never use some of our old grain bins again. In today's video, we take delivery of the new grain bin, look back at the old bins that have been part of our farm for years, and talk about why this upgrade is such a big deal for harvest, grain storage, and the future of our family farm.

This is more than just a grain bin delivery. It’s the end of an era and the start of a major farm upgrade that will completely change how we handle corn during harvest. From old grain storage to a brand-new bin setup, this project is one of the biggest improvements we’ve made at the farm.

Join me as the new grain bin shows up, the bin project continues, and we prepare for a new chapter in harvest efficiency on our Minnesota family farm.
