Seventh Biennial Conference on the Marine Transportation System Innovative Science and Technologies Toward Greater Sustainability was organized by The National Academies of Sciences, Engineering  and Medicine in partnership with the U.S. Committee on the Marine Transportation System. The conference aimed to disseminate and discuss the results of current research, practitioner experiences, and stewardship challenges with respect to the environmental sustainability of the U.S. marine transportation system (MTS). The conference identified research needs, barriers and potential progress related to overall environmental sustainability and decarbonization strategies including: the introduction of alternative fuels, vessel and port electrification, regulatory and governance reform, green technology implementation, beneficial and alternative use of dredged materials, and other environmental sustainability strategies. Particular emphasis was placed on lifecycle impacts, infrastructure requirements, vessel fleet considerations, and the necessary collaboration required among all MTS-related stakeholders and sectors.

Speakers presented recent progress in scientific and technological solutions related to environmental sustainability and the associated research being conducted in government, academia, and the private sector. A recording of the plenary sessions as well as the student honor panel and closing session is available here. The slides from the closing session are available here.
