Thune, Klobuchar Urge EPA to Update Biofuel Emissions Modeling

Two Senate Ag Committee members recently urged the Environmental Protection Agency to update its greenhouse gas modeling for biofuels. Senators John Thune, a South Dakota Republican, and Amy Klobuchar, a Minnesota Democrat, asked the EPA to adopt the Argonne National Lab’s Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation, or GREET model. The lawmakers say these long-overdue updates would permit consistent comparison between petroleum-based fuels, natural gas systems, electric generation, and renewable fuels. In a joint statement, the Senators say, “The GREET Model has been among the most widely utilized sources of GHG data, underpinning research that finds corn ethanol can currently achieve 46 percent lower lifecycle carbon intensity than gasoline.” They made the request in a letter to the EPA, also signed by seven other Midwest farm-state Senators. Thune and Klobuchar previously introduced the Adopt GREET Act, legislation that would require the EPA to update its greenhouse gas modeling for ethanol and biodiesel.
