Bill > S2261

This bill, known as the Clean Shipping Act of 2025, amends the Clean Air Act to establish comprehensive standards for reducing the carbon intensity of marine vessel fuels. The legislation applies to vessels of 400 gross tonnage or more engaged in commercial voyages between U.S. ports or between U.S. and foreign ports, requiring progressively stricter reductions in carbon intensity over time. Specifically, the bill mandates a 30% reduction in carbon intensity by 2034, escalating to a 100% reduction by 2050, with the Environmental Protection Agency (EPA) responsible for developing and implementing these standards. The bill provides flexibility for the EPA to adjust requirements if technological or economic constraints make the original targets unfeasible, and includes provisions for monitoring and reporting annual fuel use and greenhouse gas emissions. Additionally, the bill introduces in-port zero emission standards, aiming to eliminate greenhouse gas and air pollutant emissions from vessels at anchorage or berth in the contiguous U.S. zone by January 1, 2035. The legislation defines key terms like carbon intensity, lifecycle greenhouse gas emissions, and includes provisions for international standards harmonization, reporting requirements, and potential compliance credits for vessels that exceed the standards.
