Emissions model for air travel fuel will be prepared 'in the extremely future', states EPA administrator

Modifications to an essential emissions design for sustainable aviation fuel feedstocks will be ready in the very near future, said U.S. Environmental Protection Agency Administrator Michael Regan in Philadelphia on Friday.

The Biden administration vowed last year to upgrade how the Department of Energy's Greenhouse Gases, Controlled Emissions and Energy Usage in Technologies (GREET) design measures emissions from agricultural practices used by farmers producing biofuel feedstocks.

The revisions were postponed from an initial March 1 timeline after disagreements amongst companies about the changes, sources informed at the time.

In the extremely future, we will have that model up and running, Regan informed the Society for Environmental Journalists conference.

The design is preferred by the biofuels industry for determining ethanol emissions to figure out whether the fuel qualifies for a. $ 1.25 per gallon sustainable aviation fuel tax credit passed in. the Inflation Reduction Act.

The passage of the tax credit triggered a lobbying battle. in between biofuel and farm groups and ecological organizations. who argue producing fuel from crops is detrimental to. combating environment modification.

The EPA, DOE, Department of Farming, Federal. Air travel Administration, and White House have all

been included

in discussions about executing the credit.
