This bill focuses on tackling maritime pollution by mandating reporting on fuel consumption, emissions, and cargo details for specific voyages to determine fees for maritime pollution. It establishes fees on emissions from cargo vessels, introduces an alternate fee for imported cargo, and implements fees on criteria air pollutants emitted within specified areas. Additionally, it provides funding for research and development of low-carbon maritime fuels and low-emission maritime technologies. The bill also prioritizes grants and low-interest loans for vessel replacement or retrofitting using low-carbon fuels or zero-emissions technologies. It aims to reduce maritime pollution by giving priority to projects with maximum greenhouse gas reduction and public health benefits.
