A Misguided Victory for Corn

On April 28, 2025, the Environmental Protection Agency waved through an emergency waiver, allowing E-15 gasoline, a fuel blended with 15% corn ethanol, to flood pumps nationwide this summer. Touted as a win for American farmers and a step toward energy independence, the decision has sparked celebration among corn growers and biofuel advocates. Yet, beneath the surface, this move reveals a troubling disconnect. It prioritizes short-term economic gains over the urgent need to protect our environment and build a truly sustainable future for agriculture.

The announcement, championed by U.S. Secretary of Agriculture Brooke Rollins, frames E-15 as a lifeline for rural economies and a shield against volatile global energy markets. Supporters argue it lowers fuel prices and bolsters national security by reducing reliance on foreign oil. But this narrative glosses over a harsher truth. Corn ethanol production, far from being a green solution, often exacerbates environmental degradation and entrenches a system that rewards industrial agriculture at the expense of small farmers and our planet’s health.

For those who care about climate change and equitable farming, the E-15 waiver isn’t a triumph. It’s a step backward. It doubles down on a flawed strategy that ignores the science of sustainability and sidelines innovative agricultural practices. As we face rising temperatures, worsening droughts, and degraded soils, we must demand policies that prioritize long-term resilience over quick fixes.

This isn’t just about fuel. It’s about the kind of future we’re building. Are we committed to a world where clean water, healthy soil, and thriving communities come first? Or will we keep propping up a system that sacrifices our environment for the sake of outdated priorities?

The Environmental Cost of Ethanol

Corn ethanol’s environmental toll is steep. Studies from the U.S. Department of Energy show that while ethanol’s greenhouse gas emissions have dropped 23% since 2005, thanks to better yields and less fertilizer, the full picture is grim. When you factor in land-use changes, fertilizer runoff, and nitrate leaching, ethanol’s carbon footprint can rival or even surpass gasoline’s. Some research estimates it may emit 24% more carbon than traditional fuel. This isn’t the clean energy revolution we were promised.

The damage doesn’t stop at emissions. Intensive corn farming for ethanol depletes soil, erodes conservation lands, and pollutes waterways with nitrogen and pesticides. In places like Iowa and Illinois, where corn dominates, rivers and streams suffer from toxic runoff, creating dead zones in the Gulf of Mexico. Groundwater contamination is another risk, threatening drinking water for rural communities. Expanding E-15 sales only deepens these wounds, locking us into a cycle of environmental harm.

Advocates for year-round E-15 sales claim it supports farmers and cuts fuel costs. But this argument ignores the bigger picture. The ethanol boom primarily benefits large agribusinesses, not small family farms. Subsidies and market incentives flow to industrial operations, while smaller growers struggle to compete. And the supposed savings at the pump? They’re negligible, especially when weighed against the long-term costs of degraded ecosystems and compromised public health.

A Missed Opportunity for Climate-Smart Farming

The push for E-15 distracts from what American agriculture desperately needs: robust support for climate-smart practices. Programs like those funded by the Inflation Reduction Act have shown promise, channeling billions into soil health, diversified cropping, and reduced fertilizer use. These initiatives help farmers adapt to climate change while cutting emissions. Yet, the current administration has slashed some of these programs, redirecting funds to prop up ethanol and other short-term fixes.

Look to Minnesota, where the state’s Climate Strategy Framework aims to halve emissions by 2030, partly by tackling agricultural sources like methane and nitrous oxide. Or Denmark, which taxes livestock methane and incentivizes sustainable farming. These models prove we can align agriculture with climate goals. But the E-15 waiver pulls us in the opposite direction, chaining farmers to a crop that’s increasingly unsustainable in a warming world.

Small farmers, who could lead the charge in building resilient, regenerative systems, are left out. Instead of investing in their future, we’re funneling resources to a biofuel industry that’s been propped up by decades of subsidies. This isn’t progress. It’s a betrayal of the very communities we claim to support.

National Security or Corporate Welfare?

The administration’s rhetoric about energy independence and national security sounds compelling. Biofuels, they argue, shield us from global market shocks and hostile foreign actors. But this framing conveniently sidesteps who really benefits. The ethanol industry, backed by powerful agribusiness lobbies, reaps massive profits while small farmers see little of the gains. In 2024, ethanol production netted $1.3 billion in pre-tax profits, yet corn prices, which make up 80% of production costs, squeeze smaller growers caught in volatile markets.

If national security is the goal, why not invest in advanced biofuels that don’t rely on food crops? Cellulosic ethanol, made from waste or non-food plants, offers a cleaner alternative without the environmental baggage. Yet, funding for these innovations remains a fraction of what’s poured into corn ethanol. The E-15 waiver, far from securing our future, entrenches a system that prioritizes corporate interests over genuine energy resilience.

Opponents of this critique might argue that E-15 boosts rural jobs and stabilizes fuel supplies. But the jobs created are often low-wage and tied to industrial operations, not family farms. And the fuel supply argument falls flat when you consider that global oil production, not domestic policy, drives price drops. The Energy Information Administration projects a mere 11-cent-per-gallon decrease in 2025, hardly a game-changer for consumers.

A Call for a Bolder Vision

We stand at a crossroads. The E-15 waiver, cloaked in promises of economic relief and energy security, is a distraction from the real work of building a sustainable future. We need policies that empower farmers to adopt regenerative practices, protect our water and soil, and reduce emissions. We need a fuel strategy that prioritizes next-generation biofuels and renewable energy, not a relic of the 1970s oil crisis.

The path forward isn’t easy, but it’s clear. Redirect subsidies from industrial ethanol to conservation and climate-smart agriculture. Strengthen air quality standards to protect communities from smog and ozone. Invest in rural economies by supporting small farmers, not corporate giants. These steps would honor the land, the people who work it, and the generations to come.

The EPA’s decision to expand E-15 sales may feel like a quick win, but it’s a hollow one. We deserve better. Our planet demands it, and our farmers, who bear the weight of feeding us in a changing climate, deserve a system that truly works for them. Let’s fight for that future, not settle for a flawed past.
