SECTION 1. SHORT TITLE.

    This Act may be cited as the ``Sustainable Aviation Fuels Accuracy 
Act of 2023''.

SEC. 2. STANDARD, UNIFORM DEFINITION OF SUSTAINABLE AVIATION FUEL.

    (a) In General.--Not later than 60 days after the date of enactment 
of this section, the Administrator of the Federal Aviation 
Administration shall issue or revise regulations as necessary to 
provide that the definition of sustainable aviation fuel specified in 
subsection (b) applies to--
            (1) all aircraft flown to, from, or within the United 
        States; and
            (2) all programs established, administered, or overseen by 
        the Federal Aviation Administration.
    (b) Sustainable Aviation Fuel Defined.--
            (1) In general.--For purposes of subsection (a), the term 
        ``sustainable aviation fuel'' means liquid fuel, the portion of 
        which is not kerosene, which--
                    (A) meets the requirements of--
                            (i) ASTM International Standard D7566; or
                            (ii) the Fischer Tropsch provisions of ASTM 
                        International Standard D1655, Annex A1;
                    (B) is not derived from coprocessing an applicable 
                material (or materials derived from an applicable 
                material) with a feedstock which is not biomass;
                    (C) is not derived from palm fatty acid distillates 
                or petroleum; and
                    (D) has been certified in accordance with paragraph 
                (2)(C) as having a lifecycle greenhouse gas emissions 
                reduction percentage of at least 50 percent.
            (2) Other definitions.--For purposes of paragraph (1):
                    (A) Applicable material.--The term ``applicable 
                material'' means--
                            (i) monoglycerides, diglycerides, and 
                        triglycerides,
                            (ii) free fatty acids, and
                            (iii) fatty acid esters.
                    (B) Biomass.--The term ``biomass'' has the meaning 
                given such term in section 45K(c)(3) of the Internal 
                Revenue Code of 1986.
                    (C) Lifecycle greenhouse gas emissions reduction 
                percentage.--The term ``lifecycle greenhouse gas 
                emissions reduction percentage'' means, with respect to 
                any sustainable aviation fuel, the percentage reduction 
                in lifecycle greenhouse gas emissions achieved by such 
                fuel as compared with petroleum-based jet fuel, as 
                defined in accordance with--
                            (i) the most recent Carbon Offsetting and 
                        Reduction Scheme for International Aviation 
                        which has been adopted by the International 
                        Civil Aviation Organization with the agreement

                            (ii) the most recent determinations under 
                        the Greenhouse gases, Regulated Emissions, and 
                        Energy use in Transportation (GREET) model 
                        developed by Argonne National Laboratory or any 
                        successor model developed by Argonne National
