America Was Wrong About Ethanol - Study Shows

Summary by Krater

This video examines a study from the University of Wisconsin-Madison by Tyler Lark regarding the carbon intensity of corn ethanol compared to gasoline. It concludes that corn-based ethanol has higher greenhouse gas emissions than gasoline due to land use changes and soil carbon release, making it counterproductive to climate goals.

From the video

Answers: Is corn ethanol better for the environment than gasoline?

• corn ethanol carbon intensity
• Renewable Fuel Standard
• land use change greenhouse gas emissions
• EPA regulatory impact analysis
• soil carbon release from plowing
• biofuel environmental outcomes

What it concludes

• The full lifecycle carbon intensity of corn-based ethanol is at least 24% higher than gasoline.
• Land use changes and soil carbon release from converting grasslands to corn production generate massive carbon emissions that can wipe out any climate benefits of biofuels.
• Encouraging biofuels that only achieve a 20% improvement over fossil fuels is insufficient due to wide margins of uncertainty in lifecycle analyses.
