Sustainable Aviation Fuels Accuracy Act of 2023

To identify the standards required to meet the definition of sustainable aviation fuel at the Federal Aviation Administration. 1. Short title This Act may be cited as the Sustainable Aviation Fuels Accuracy Act of 2023 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 (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 (i) monoglycerides, diglycerides, and triglycerides, (ii) free fatty acids, and (iii) fatty acid esters. (B) Biomass The term biomass section 45K(c)(3) (C) Lifecycle greenhouse gas emissions reduction percentage The term lifecycle greenhouse gas emissions reduction percentage (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 of the United States; or (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 Laboratory.

Summary: Sustainable Aviation Fuels Accuracy Act of 2023 This bill defines the standards that apply to sustainable aviation fuel at the Federal Aviation Administration (FAA). The FAA must issue or revise regulations as necessary to provide that the bill's definition of sustainable aviation fuel applies to (1) all aircraft flown to, from, or within the United States; and (2) all programs established, administered, or overseen by the FAA. Under the bill, sustainable aviation fuel means liquid fuel, the portion of which is not kerosene, which (1) meets specific international standards, (2) is not derived from coprocessing specific materials (e.g., triglycerides) with a non-biomass feedstock, (3) is not derived from palm fatty acid distillates or petroleum, and (4) is certified as having a lifecycle greenhouse gas emissions reduction percentage of at least 50% compared with petroleum-based jet fuel (based on specific standards and agreements).
