Corn Ethanol Is Worse for the Climate Than the Keystone XL Pipeline, According to EPA's Own Estimates

Do you think the federal government couldn’t order something worse for the environment than the Keystone XL oil pipeline?

Think again.

Using the U.S. Environmental Protection Agency’s (EPA) own estimate, we calculate that the corn ethanol mandate has been worse for the climate than projected emissions from the controversial Keystone XL pipeline.

What makes matters worse is that the U.S. EPA just mandated that more corn ethanol must go into American gas tanks.

Last week the EPA proposed new minimum volumes of corn ethanol that refiners would be required to  blend into gasoline this year and the next. Congress set this policy, called the Renewable Fuel Standard, in the Energy Independence and Security Act of 2007. At the time, lawmakers hoped that using ethanol and other renewable fuels would reduce carbon emissions and American dependence on foreign oil.

Last year, corn ethanol producers churned out 14 billion gallons, about 13.4 billion gallons of which were blended into the 135 billion gallons of gasoline the nation’s drivers used.

Extracting tar sands and turning them into oil is more energy-intensive than traditional drilling for petroleum. According to the Natural Resources Defense Council, dirty oil transmitted from Alberta, Canada, to the Gulf Coast by the Keystone XL pipeline would emit 24 million tons of carbon per year.

But our calculations show that last year’s production and use of 14 billion gallons of corn ethanol resulted in 27 million tons more carbon emissions than if Americans had used straight gasoline in their vehicles. That’s worse than Keystone’s projected emissions. It’s the equivalent of emissions from seven coal-fired power plants.*

So far the federal corn ethanol mandate has resulted in a massive influx of dirty corn ethanol, which is bad for the climate and bad for consumers. The only interest it benefits is the ethanol industry.

As we’ve said before, it’s time for Congress to correct course and reform the broken Renewable Fuels Standard to make way for truly green biofuels.

5 Environmental Victories to Inspire You This Earth Day

Planet Earth is at a crisis point. Researchers say we have to begin reducing carbon dioxide emissions by 2020 if we want to meet the temperature goals outlined in the Paris agreement and avoid catastrophic climate change.

The work to be done can seem overwhelming. A survey published this week found that only 6 percent of Americans think we will succeed in reducing global warming.

Iceland to Resume Killing Endangered Fin Whales

By Kitty Block

Iceland seems to be the most confused of nations when it comes to whales. On the one hand it attracts international tourists from all over the world to go out and see whales as part of their encounters with Iceland's many natural wonders. On the other hand it kills whales for profit, with some portion of the kill even being fed to some of the same tourists in restaurants and cafes.
