Klobuchar-Thune bill puts ethanol in climate-friendly light

Two Midwest senators have reintroduced legislation that could cast a more positive environmental light on ethanol, as both sides in the biofuel debate prepare for a new White House administration driven to tackle greenhouse gas emissions. Sens. Amy Klobuchar (D-Minn.) and John Thune (R-S.D.) proposed the “Adopt GREET Act,” which would require EPA to update greenhouse gas modeling for ethanol and biodiesel, adopting a measurement from the Argonne National Laboratory. The lab’s model is called the Greenhouse Gases, Regulated Emissions and Energy Use in Transportation Model, or GREET. A similar bill in the last Congress had three co-sponsors and didn’t advance, but it would address an issue that’s pressing as the Biden administration weighs the future of the federal renewable fuel standard: How do biofuels play into climate policy? And should officials view them as a tool to reduce greenhouse gas emissions compared with petroleum?
