Sustainable transportation in the United States encompasses energy-efficient and affordable modes of transport, emphasizing electric and alternative-fuel vehicles as well as domestic fuels. The benefits of sustainable transportation in the US are significant, including cost savings on fuel and vehicles, reduced air pollution, job creation, improved accessibility to transportation options, enhanced energy security, and lower carbon emissions. The Office of Energy Efficiency and Renewable Energy (EERE) plays a crucial role in funding research and development (R&D) to enhance the sustainability and efficiency of transportation modes, including aviation, maritime, rail, and road vehicles. EERE also focuses on advancing technologies like hydrogen and sustainably sourced biomass to position the US as a global leader in new sectors. Collaboration with agencies like the U.S. Department of Transportation and Housing aims to modernize the transportation sector through initiatives such as the U.S. National Blueprint for Energy and Emissions Innovation in Transportation. Alternative fuels, including hydrogen, are highlighted for their role in running sustainable transportation options, improving energy efficiency, and reducing emissions, thus contributing to a positive impact on the environment and economy.
