Legislation would require EPA to update GREET

Sen. John Thune, R-S.D., introduced the Adopt GREET Act, which would require U.S. EPA to update its decade-old greenhouse gas lifecycle modeling for ethanol and biodiesel. American Coalition for Ethanol CEO Brian Jennings issued the following statement in support of the concept of the legislation:

“ACE has long called for adoption of the newest lifecycle science to quantify ethanol’s contributions to reducing greenhouse gas emissions and we have worked collaboratively with Department of Energy scientists to improve the assumptions used in their GREET model, most notably through the white paper we published in 2018, “The Case for Properly Valuing the Low Carbon Benefits of Corn Ethanol.”

“Current data from the GREET model indicate that corn ethanol’s carbon intensity is approximately 50 percent less than petroleum gasoline providing significantly more greenhouse gas reduction benefits than when the RFS was enacted over a decade ago. Senator Thune’s legislation is another pointed reminder that EPA must do better in its treatment of ethanol’s greenhouse gas benefits compared to gasoline. Updating EPA’s antiquated modeling would be a step in the right direction to underpin the scientific and economic opportunity for ethanol use to increase via low carbon fuel markets.”

The Adopt GREET Act was cosponsored by Sens. Mike Rounds, R-S.D.; Chuck Grassley, R-Iowa; and Joni Ernst, R-Iowa.
