California Senators Introduce Bills to Reduce Air Pollution in Shipping Industry

Strategic Insights

— 1 min read

California Senators Alex Padilla and Sheldon Whitehouse introduced two bills to tackle air pollution in the shipping industry. The Clean Shipping Act of 2025 and the International Maritime Pollution Accountability Act aim to reduce greenhouse gas emissions and air pollution from shipping, protecting coastal communities and the environment. The bills come as part of a growing effort to address the climate crisis and promote sustainable practices in the maritime industry.

Key Takeaways:

  • The Clean Shipping Act of 2025 sets a path to eliminate greenhouse gas emissions from all ocean shipping companies that do business with the United States by 2050.
  • The bill directs the Environmental Protection Agency (EPA) to set progressively tighter carbon intensity standards for fuels used by ships, reducing emissions by up to 100% by 2050.
  • The International Maritime Pollution Accountability Act imposes a pollution fee on the largest marine vessels offloading cargo at U.S. ports, driving industry-wide decarbonization efforts and incentivizing the use and development of cleaner maritime fuels.
  • The fee would apply to ships with 5,000 gross tonnage or more, excluding most of the domestic industry.
  • The bills have received endorsements from a range of organizations, including industry leaders and NGOs, highlighting widespread support for the legislation.

Statistics:

  • The global shipping industry emits approximately one billion tons of greenhouse gas emissions per year, roughly 3% of total anthropogenic global-warming carbon-dioxide emissions. (Source: International Maritime Organization 2020 GHG Study)
  • Shipping's GHG emissions could more than double between 2018 and 2050, according to the study. (Source: International Maritime Organization 2020 GHG Study)
  • One in three Latines live in the top 20% of most pollution-impacted communities. (Source: GreenLatinos)
  • 1.3 billion people live within three miles of a port, and maritime shipping is a major source of climate-warming pollution and air pollutant emissions. (Source: Senators' press release)
