Ethanol Vehicles A Threat To Human Health

Let our journalists help you make sense of the noise: Subscribe to the Mother Jones Daily newsletter and get a recap of news that matters.


A new Stanford University study predicts that if every vehicle in the United States ran on fuel made primarily from ethanol the number of respiratory-related deaths and hospitalizations would increase. “Ethanol is being promoted as a clean and renewable fuel that will reduce global warming and air pollution,” says atmospheric scientist Mark Z Jacobson, associate professor of civil and environmental engineering. “But our results show that a high blend of ethanol poses an equal or greater risk to public health than gasoline, which already causes significant health damage.” Jacobson used a computer model to simulate air quality in 2020, when ethanol-fueled vehicles are expected to be widely available.

While E85 vehicles (those running on 85 percent ethanol and 15 percent gasoline) reduced two carcinogens, benzene and butadiene, they increased two others, formaldehyde and acetaldehyde. In some parts of the country, E85 also significantly increased ozone, a prime ingredient of smog. The World Health Organization estimates that 800,000 people die each year from smog. Furthermore, the deleterious health effects of E85 will be the same, whether the ethanol is made from corn, switchgrass or other plant products.

“There are alternatives, such as battery-electric, plug-in-hybrid and hydrogen-fuel cell vehicles, whose energy can be derived from wind or solar power,” Jacobson says. These vehicles produce virtually no toxic emissions or greenhouse gases and cause very little disruption to the land–unlike ethanol made from corn or switchgrass, which require millions of acres of farmland to mass-produce. “It would seem prudent, therefore, to address climate, health and energy with technologies that have known benefits.”

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
