The AAERO Act amends federal aviation fuel programs to increase funding and support for sustainable aviation fuel production. The bill authorizes approximately $703 million in additional funding for fiscal year 2024 to help develop and deploy technologies that produce sustainable aviation fuel meeting specific emissions reduction standards. The legislation modifies grant eligibility criteria to prioritize projects that can scale to meet national production goals, which aim to supply sufficient sustainable aviation fuel to meet 100 percent of aviation demand by 2050. The changes apply to aviation fuel manufacturers, technology developers, and businesses in the renewable fuel sector seeking federal grants. The bill defines sustainable aviation fuel as liquid fuel achieving at least a 50 percent reduction in lifecycle greenhouse gas emissions compared to conventional jet fuel, using established scientific methodologies to measure emissions benefits.
