; (B) the amount of fuel used for each covered voyage; and (C) the total greenhouse gas emissions measured in carbon dioxide equivalent for all covered voyages. (3) Annual report Not later than 6 months after the end of each annual reporting period under paragraph (2), the Administrator, in consultation with the Secretary of Transportation and Commandant of the Coast Guard, shall publish a report that— (A) compiles the data reported under paragraph (2); and (B) includes an explanation intended to facilitate public understanding of— (i) the carbon dioxide equivalent emissions of vessels on covered voyages; and (ii) the carbon intensity of fuels used by such vessels. (c) Enforcement The standards established under subsection (a) and the annual reporting requirements of subsection (b)(2) shall be considered an emission standard or limitation for purposes of section 304(a)(1). (d) Definitions In this section: (1) Carbon dioxide equivalent The term carbon dioxide equivalent means the number of metric tons of carbon dioxide emissions with the same global warming potential as one metric ton of another greenhouse gas, as calculated using Equation A–1 in section 98.2(b) of title 40, Code of Federal Regulations, as in effect on the date of enactment of this section. (2) Carbon intensity The term carbon intensity means the quantity of lifecycle greenhouse gas emissions per unit of fuel energy, expressed in grams of carbon dioxide equivalent per megajoule. (3) Carbon intensity baseline The term carbon intensity baseline means the average carbon intensity of the fuel used by all vessels on covered voyages in calendar year 2024. (4) Covered voyage The term covered voyage means any voyage of a vessel for the purpose of transporting passengers or cargo for commercial purposes— (A) that is between any ports of call under the jurisdiction of the United States
