About SAFE-T

SAFE-T was developed by Energy and Environmental Research Associates, LLC. (EERA) with funding from the U.S. Department of Transportation - Maritime Administration (MARAD) Maritime Environmental and Technical Assistance (META) Program. More information about META is available here.

SAFE-T provides tools enabling shippers to track fuel use and emissions, compare the carbon intensity of different shipping routes, and compare properties of conventional and alternative marine fuels.

SAFE-T is a user-friendly, web-based suite of tools that allow users to evaluate emissions and greenhouse gas reduction strategies for shipping. SAFE-T was built from a robust blend of literature analysis, evaluation of comparable tools, input from stakeholders, and comprehensive examination of key subject matters. SAFE-T is built on international standards and methodologies.
