Bill > S1917

This bill, the Clean Shipping Act of 2023, amends the Clean Air Act to establish standards to limit the carbon intensity of the fuel used by certain vessels. Specifically, it requires the Environmental Protection Agency (EPA) Administrator to promulgate regulations that would reduce the carbon intensity of fuel used by vessels on "covered voyages" (i.e., voyages between U.S. ports or between a U.S. port and a foreign port) by at least 20% by 2029, 45% by 2034, 80% by 2039, and 100% by 2040 and thereafter. The bill also allows the Administrator to adopt more lenient standards if the required reductions are not technologically or economically feasible, and to harmonize the standards with international requirements set by the International Maritime Organization. Additionally, the bill requires vessels to monitor and report on the carbon intensity and greenhouse gas emissions of their fuel use, and empowers the EPA to enforce the standards.
