A new report by UMAS, commissioned by The Ocean Conservancy titled "The Maritime Fleet of the USA-the current status and potential for the future" shows, for the first time, the scale of U.S. shipping fleet emissions and opportunities to decarbonise the sector. In 2018, carbon emissions from all U.S.-flagged vessels amounted to around 26 million tonnes, approximately 2.4% of global shipping emissions. Domestic shipping voyages accounted for about 70% of carbon emissions from the U.S.-flagged shipping fleet, which presents a unique opportunity for U.S. actions to effectively decarbonize the American maritime sector.
