Corn Ethanol: A Lump of Coal in Your Christmas Stocking
You know that feeling of great anticipation... only to have it followed by complete and utter disappointment? (Here's a good seasonal example.)
Well, that feeling fits corn ethanol nicely.
In 2007, corn ethanol was offered up as an environmentally friendly alternative to gasoline. But nearly seven years to the day since Congress put it in play, we're still not seeing the benefits. In fact, quite the opposite.

You know that feeling of great anticipation... only to have it followed by complete and utter disappointment? (Here's a good seasonal example.)
Well, that feeling fits corn ethanol nicely.
In 2007, corn ethanol was offered up as an environmentally friendly alternative to gasoline. But nearly seven years to the day since Congress put it in play, we're still not seeing the benefits. In fact, quite the opposite.
Earlier this week, the Proceedings of the National Academy of Sciences, a prestigious scientific journal, published a paper by University of Minnesota researchers Christopher W. Tessum, Jason D. Hill and Julian D. Marshall, which concluded that, "powering vehicles with corn ethanol... increases monetized environmental health impacts by 80 percent or more relative to using conventional gasoline."
In layman's terms, that means that corn ethanol is worse for the environment and people's health than we thought. And the more we learn, the more it's clear it's not even close.
Why? Because the process that produces corn ethanol involves heavy agricultural production and fertilizer use, which trump any potential benefits.
After the federal Renewable Fuel Standard was signed into law in 2007, many corn growers decided to plant corn year after year to profit from higher prices, rather than switching between corn and soybeans, for example. This transition has greatly harmed air and water quality.
The impact is greatest in the American Corn Belt - the Midwest and parts of the Mississippi River watershed where corn production is centered - as shown by this image from the PNAS paper, where the density of red represents the amount of air pollution due to corn ethanol production.
According to the analysis, the air quality degradation caused by producing corn ethanol could lead to 1,500 extra deaths a year. The air pollution caused by corn ethanol leads to hundreds of more deaths than the corresponding toll from gasoline, so corn ethanol results in greater economic losses.
And that's not all. In May of this year, an EWG report titled "Ethanol's Broken Promise" showed that reducing the amount of corn ethanol blended into gasoline would lower greenhouse gas emissions.
Moreover, corn ethanol is not just damaging the air; it's affecting water quality, too.
In September, the Environmental Protection Agency's inspector general concluded that corn ethanol is a major cause of water pollution in the Mississippi River basin and Gulf of Mexico.
And if that wasn't enough, corn ethanol also lowers your car's gas mileage.
With each passing month, the evidence against corn ethanol mounts.
As Congress turns its focus to 2015, it should take a serious look at reforming the Renewable Fuel Standard in order to phase out corn ethanol and bring truly green biofuels to the market.
No one likes an utter disappointment.
An Urgent Message From Our Co-Founder
Dear Common Dreams reader, It’s been nearly 30 years since I co-founded Common Dreams with my late wife, Lina Newhouser. We had the radical notion that journalism should serve the public good, not corporate profits. It was clear to us from the outset what it would take to build such a project. No paid advertisements. No corporate sponsors. No millionaire publisher telling us what to think or do. Many people said we wouldn't last a year, but we proved those doubters wrong. Together with a tremendous team of journalists and dedicated staff, we built an independent media outlet free from the constraints of profits and corporate control. Our mission has always been simple: To inform. To inspire. To ignite change for the common good. Building Common Dreams was not easy. Our survival was never guaranteed. When you take on the most powerful forces—Wall Street greed, fossil fuel industry destruction, Big Tech lobbyists, and uber-rich oligarchs who have spent billions upon billions rigging the economy and democracy in their favor—the only bulwark you have is supporters who believe in your work. But here’s the urgent message from me today. It's never been this bad out there. And it's never been this hard to keep us going. At the very moment Common Dreams is most needed, the threats we face are intensifying. We need your support now more than ever. We don't accept corporate advertising and never will. We don't have a paywall because we don't think people should be blocked from critical news based on their ability to pay. Everything we do is funded by the donations of readers like you. When everyone does the little they can afford, we are strong. But if that support retreats or dries up, so do we. Will you donate now to make sure Common Dreams not only survives but thrives? —Craig Brown, Co-founder |
