Biofuels Policy, a Mainstay of American Agriculture, a Failure for the Climate

a year ago

The American Midwest's farmland has been transformed into a major corn- and soy-producing region, largely due to biofuel policies.
A new report criticizes the ethanol industry for causing economic and social imbalances in rural communities and increasing greenhouse gas emissions.
The report, by the World Resources Institute, concludes that U.S. ethanol policy has largely failed and should be reconsidered.
Corn-based ethanol has contributed to nutrient runoff, degraded water quality, and harmed wildlife habitats.
Between 2004 and 2024, ethanol production increased by nearly 500%, with about 30 million acres of land used for ethanol production instead of food crops.
The biofuels industry claims ethanol is an energy-efficient alternative to fossil fuels, but research suggests it may produce more greenhouse gases.
Biofuel refiners emit significant amounts of carcinogenic substances, including hexane and formaldehyde, in greater amounts than petroleum refineries.
Increased biofuel production could raise greenhouse gas emissions due to land clearing in other countries and nitrogen-based fertilizer use.
The report states that the benefits of biofuels are concentrated among a few, while farmland consolidation locks out emerging or low-resource farmers.
New policies, including tax credits for biofuels, could expand production, potentially increasing land conversion and greenhouse gas emissions.
