Model for Jet Fuel Tax Credit is Delayed, Official Says

By Jael Holzman

The White House is delaying the long-expected release of a key model for companies to qualify for the IRA’s sustainable aviation fuel tax credit.

Why it matters: From aviation to agriculture, many companies are eagerly awaiting this model, which measures jet fuel’s lifecycle carbon emissions.

Driving the news: The Biden administration won’t meet the March 1 deadline it previously set for releasing an updated version of GREET, per a White House official familiar with the situation.

• The GREET model is a greenhouse gas measurement tool previously used for federal ethanol mandates.
• The updated version is supposed to incorporate climate activists’ concerns that more SAF would mean much more land use, which can potentially have deleterious climate impacts.

Expect the update in “weeks, not months,” said the official, who requested anonymity to candidly discuss the situation.

• “We just haven’t finished dotting every ‘i’ and crossing every ‘t’ … We know that this is eagerly anticipated.”
