What it does
This bill creates a federal fee system on international shipping vessels to address maritime pollution. Starting in 2027, the EPA will charge shipping operators fees based on the carbon emissions and air pollutants (nitrogen oxides, sulfur dioxide, particulate matter) from their cargo vessels. The fees are designed to incentivize cleaner shipping practices, with revenues recycled into grants and loans for vessel modernization, clean fuel development, port electrification, and workforce training. Importers can also be charged fees on cargo brought into the US, though credits apply if the vessel already paid fees under international maritime rules.
Why we flagged it
The bill's core mechanism is a polluter-pays fee on maritime shipping emissions, with mandatory revenue recycling into clean transportation infrastructure and workforce development. This is fundamentally an environmental regulation paired with public investment, not a subsidy or carve-out.
What the text implies
- Fee structure may increase import costs for US consumers, with incidence depending on whether shipping companies absorb or pass through costs; importers bear direct fee liability for cargo brought into US.
- Jones Act vessel exemption from certain fee provisions may create competitive advantage for domestic shipping, potentially raising domestic shipping costs relative to international alternatives.

Who stands to gain
Domestic shipping companies (Jones Act vessel owners receiving modernization grants); Clean fuel producers and maritime technology developers (R&D grant recipients); Port authorities and state/local governments (electrification and workforce training grants)
