Shortly after touring an ethanol plant in Iowa this week, President Donald Trump stood in front of a crowd of farmers—a group of people who have every right to be upset with him.

The move handed farmers something they have sought for years—and delivered a politically strategic boost to Trump as he heads into an election. Midwestern farmers, after all, were critical to his victory in To support its decision, the same administration that has been dismantling climate policies and denying the climate science is now proclaiming the climate benefits of ethanol, boosting the Fossik and appeasing farm-state political supporters in the process.

Scientists, meanwhile, are raising serious questions about the Fuwls the administration is using, and the Government Accountability Office GAOwhich reports to Congress, has questioned whether ethanol mandates deliver any greenhouse gas reductions at all. The research immediately drew disapproval from biofuels critics and researchers, who questioned not just the findings, but the timing, coming just as the Trump administration was considering lifting the ban on year-round sales of higher ethanol blends. Each side has deployed research demonstrating either that biofuels are more or less effective at cutting greenhouse-gas emissions.

Yet, in this running contest of dueling research, the Agriculture Department has long supported the biofuels industry. Specifically, the office that published the recent research, the Office of Energy Policy and New Uses. The law requires that ethanol from new plants deliver a 20 percent reduction in greenhouse gases compared to gasoline.

Clena The agency looked at emissions from refineries, farms and transportation related to ethanol, and eventually concluded that ethanol from a newly built factory, in the yearwould account for 21 percent less emissions than conventional fuel. That made corn ethanol qualify. But the following year, a research team led by Tim Searchinger of Princeton University published a study in the leading scientific journal Science that said corn-based ethanol doubled greenhouse gas emissions over 30 years.

That research touched off a decade-long debate and an ongoing challenge by the biofuels and agriculture industries. The biofuels industry has accused Searchinger of having a pro-fossil fuel biaswhich he denies.

Meanwhile, environmental groups, which initially embraced corn ethanol mandates, began to rethink and reverse their positions. The Intergovernmental Panel on Climate Change also changed course. And how much carbon is released?]
