U.S. Action Plan targets zero emissions for maritime sector by 2050

In Washington D.C., The United States has released its Action Plan for Maritime Energy and Emissions Innovation, outlining a roadmap to achieve near-total greenhouse gas reductions in the maritime sector by 2050. The plan introduces the “Sustainable Maritime Fuel Grand Challenge,” a public-private initiative to accelerate the adoption of low- and zero-emission fuels like green ammonia and methanol, while modernizing shipbuilding and port infrastructure.

Building on the 2023 National Blueprint for Transportation Decarbonization, the plan prioritizes technologies tailored to vessel types: electrification for harbor craft, biofuel and methanol adoption for ocean-going vessels, and hybrid solutions for non-commercial vessels. “Achieving net-zero GHG emissions requires bold action,” states the report, emphasizing collaboration across government, industry, and international stakeholders.

The plan also underscores the need for global partnerships, aligning with International Maritime Organization goals to increase the use of zero-emission fuels to at least 5% of global maritime energy by 2030.

In a critical step, the U.S. will define sustainable maritime fuels by 2025, focusing on environmental and socio-economic sustainability. With maritime shipping responsible for significant emissions, the plan positions the U.S. as a leader in decarbonizing international logistics while supporting domestic infrastructure growth and clean energy transitions.
