The Clean Shipping Act of 2025 aims to reduce the carbon emissions from vessels that transport goods and passengers. The main goal is to establish standards that limit the carbon intensity of the fuel used by these vessels, thereby addressing climate change and improving air quality. The Act introduces specific requirements for vessels on commercial voyages. It sets progressive targets for reducing carbon intensity, starting with a 30 percent reduction from a baseline established in 2027, increasing to a complete elimination of carbon emissions by 2050.
