International Maritime Pollution Accountability Act of 2025

This bill imposes fees on carbon dioxide-equivalent emissions and criteria air pollutants from international maritime shipping. It requires operators of large cargo vessels (5,000+ gross tons) to report emissions data and pay fees based on fuel consumption and emissions. The fees collected will fund programs to modernize U.S. shipping fleets with zero-emission technology, develop low-carbon fuels, train workers for clean shipping technologies, and improve air quality monitoring in port communities. The bill affects international shipping operators and U.S. port communities, with reporting requirements starting in 2027 and funding programs beginning in 2029.
