1. Short title This Act may be cited as the International Maritime Pollution Accountability Act of 2023 . 2. Findings Congress finds that— (1) the greenhouse gas emissions from the marine shipping industry— (A) account for nearly 3 percent of total global anthropogenic carbon dioxide emissions; and (B) are increasing rapidly; (2) the International Maritime Organization has failed to require emissions reductions with respect to marine shipping that are consistent with global decarbonization targets; and (3) ports are a large source of air pollution and contribute to poor air quality in the neighborhoods surrounding the ports, leading to worse health outcomes for those who live in those neighborhoods. 3. Definitions In this Act: (1) Administrator The term Administrator means the Administrator of the Environmental Protection Agency. (2) Calendar quarter The term calendar quarter means a period of 3 calendar months that ends on, as applicable, March 31, June 30, September 30, or December 31 of the applicable calendar year. (3) Cargo or freight The term cargo or freight does not include— (A) passengers transported for compensation or hire; (B) bunker fuel; (C) ship's stores; (D) sea stores; or (E) the legitimate equipment necessary to the operation of a vessel. (4) Covered voyage (A) In general The term covered voyage means a voyage— (i) made using a self-propelled vessel of 10,000 gross tonnage or more, the primary purpose of which is transporting cargo or freight; and (ii) that begins when the vessel leaves the port of origin and terminates when the offloading operations at the final port of call are completed. (B) Exceptions The term covered voyage does not include a voyage— (i) that has been included as an OCS source (as defined in subsection (a)(4) of section 328 of the Clean Air Act ( 42 U.S.C. 7627 )) because the voyage has the potential to emit any air pollutant as described in subparagraph (C)(i) of that subsection and is, as a result, regulated pursuant to that section
