Clean Shipping Act of 2023
The Clean Shipping Act of 2023 (S 1917) requires commercial vessels over 400 gross tons operating on U.S. routes (between U.S. ports or U.S. to foreign ports) to gradually reduce the carbon intensity of their fuel. It sets phased targets: 20% less carbon intensity by 2029, 45% by 2034, 80% by 2039, and 100% by 2040, compared to a 2024 baseline. Vessels must report annual fuel carbon intensity and emissions, with exemptions for voyages under 30 days and allowances for averaging emissions across vessels under common ownership. The bill also mandates in-port emission reductions for greenhouse gases and air pollutants by 2030, with feasibility adjustments allowed.
