International Maritime Pollution Accountability Act of 2024

The International Maritime Pollution Accountability Act of 2024 requires operators of large cargo vessels (10,000+ gross tons) to report detailed emissions and voyage data starting January 1, 2025. It establishes fees for carbon dioxide-equivalent emissions ($150 per metric ton, adjusted for inflation) and for criteria air pollutants like nitrogen oxides and sulfur dioxide. The fees collected fund specific programs including modernizing U.S. shipping vessels to use low-carbon fuels, developing clean maritime technologies, workforce training, and port air monitoring. The bill targets emissions from the marine shipping industry, which accounts for nearly 3% of global carbon dioxide emissions and contributes to poor air quality near port communities. The law includes provisions to recognize foreign pollution fees and sunset provisions when international standards meet or exceed U.S. requirements.
