Clean Shipping Act of 2025

Reduction in Fuel Carbon Intensity: The bill requires vessels on covered voyages to reduce the carbon intensity of their fuel by specific percentages over time, starting at 30 percent less than the baseline in 2030 and reaching a 100 percent reduction by 2050 (Section 2(b)(1)).

Elimination of In-Port Emissions: The Act mandates the creation of standards to eliminate greenhouse gas and air pollutant emissions from vessels at anchorage or berth in the contiguous zone of the United States by January 1, 2035 (Section 3(e)(1)).

Public Transparency: The Administrator is required to publish a publicly accessible report on the EPA website regarding vessel emissions data, which is intended to facilitate public understanding of carbon dioxide-equivalent emissions and fuel carbon intensity (Section 2(c)(3)(A)).

Consideration of Public Health and Environment: When determining the feasibility of standards, the Administrator must consider the potential adverse impacts on public health, safety, and the environment, including air and water quality (Section 2(b)(3)(B) and Section 3(e)(3)).

Economic and Technological Feasibility Risks: While the Administrator can adjust standards if they are not feasible, the bill places heavy reduction requirements on vessels that must be met by specific deadlines (Section 2(b)(1) and Section 2(b)(3)).

Reporting Burdens: Vessel owners or operators are required to perform annual reporting of carbon intensity, fuel use, and total greenhouse gas emissions for all covered voyages (Section 2(c)(2)).
