Sen. Thune introduces Adopt GREET Act to push EPA to update GHG modeling for biofuels

In Washington, U.S. Sen. John Thune (R-S.D.) introduced the Adopt GREET Act, legislation that would require the Environmental Protection Agency (EPA) to update its greenhouse gas (GHG) modeling for ethanol and biodiesel. Specifically, the bill would require EPA to adopt either the Argonne National Lab’s Greenhouse Gas and Regulated Emissions and Energy Use in Transportation (GREET) Model or the 2019 U.S. Department of Agriculture (USDA) methodology within 90 days of enactment. For biodiesel, EPA would be required adopt the GREET Model. EPA would then be required to update its modeling every five years or report to Congress to affirm its modeling is current or otherwise explain why no updates were made.
