The study shows that RFS contributes more to global warming than traditional gasoline

A recent study Proceedings of the National Academy of Sciences state that corn ethanol contributes more to global warming than pure gasoline.

Tyler Lark, a University of Wisconsin scientist and lead author of the study, tells Brownfield that the results show that biofuels are not a climate solution. “Corn ethanol, which was originally intended to reduce global warming, greenhouse gas emissions, is likely to increase compared to gasoline, also contributing to further increases in soil erosion, nutrient pollution and habitat loss. . ”

The study looked at the environmental impact of the Renewable Fuels Standard after it was implemented in 2007. It was found that ethanol is likely to be at least 24 percent more carbon consuming than gasoline due to emissions from land use change for maize cultivation together with processing and burning.

Lark says the US policy on renewable fuels has unintended consequences for the environment. “What is really needed are policies that can stimulate and stimulate concomitant conservation and reward farmers and agricultural practices that produce truly valuable food production, but also ecosystem services such as clean water, healthy soils and wildlife habitat.”

Scott Richman, chief economist at the Renewable Fuels Association, tells Brownfield ethanol does not they have higher greenhouse gas emissions than fossil fuels. “A lot of other studies come up with something similar in the range of 40 to 50 percent carbon intensity reduction for ethanol over gasoline.”

He says Brownfield outsiders like Argon National Lab and the California Resources Board have had consistent results in determining the environmental impact of ethanol. “The paper released this week is a complete outlier and is a function of the methodology and the way they proceeded.”

A USDA study launched in 2019, found that corn ethanol emissions would be 21% lower than gasoline.
