(NewsDakota.com/NAFB) – Midwest lawmakers this week introduced the Sustainable Aviation Fuels Accuracy Act of 2023. The bipartisan legislation would update federal standards to align with the definition of sustainable aviation fuel at the Federal Aviation Administration.

The bill would also require agencies to adopt the Greenhouse gases, Regulated Emissions, and Energy use in Technologies, or GREET Model, the most accurate tool for measuring lifecycle emissions. Iowa Republican Senators Chuck Grassley and Joni Ernst introduced the bill along with Deb Fischer from Nebraska, and Democrat Tammy Duckworth of Illinois.

Grassley says, “Our bill fixes the problem by requiring the FAA reference the most accurate GREET model for emissions assessments, consistent with many other federal agencies.” The GREET Model was commissioned by the Department of Energy’s Argonne National Laboratory. It considers crops, land uses and carbon reduction practices and is the best available model that recognizes the agriculture industry’s contributions to advancing domestic energy goals.
