U.S. Ag Secretary Tom Vilsack says he’s hopeful updates to the GREET modeling used to measure transportation emissions for sustainable aviation fuel will be announced this month.
“Well I am particularly hopeful that we get some direction from Treasury in the next several weeks, sometime during the month of April. That’s the goal, (and) certainly our goal.”
The transportation emission guidelines for SAF were expected to be announced last month.
He says the initial framework will probably focus on 40B.
