Biden Admin Delays Release of Aviation Fuel Climate Models

Models Need More Tweaking Before Publication The Biden administration was set to unveil new modeling to gauge the effect of sustainable aviation fuels on the climate, citing disagreements among developers. The revised model is supposed to help gauge whether corn-based ethanol derivatives will be able to qualify for credits when used in SAF development. The admin had said the corn industry could use the Department of Energy’s Greenhouse Gases, Regulated Emissions and Energy Use in Technologies model after suitable revisions to some of its internal modeling. Initially the White House said that it would be published on March 1st, but now that’s been pushed back a few weeks.
