Transportation sector contributes to the American economy by assuring the flow of goods across the world’s largest consumer market. Three major groups of companies are organized under the transportation industry- Shipping, passenger transport and equipment manufacturers. Sub sectors include Air and express delivery services (EDS), Freight rail, Logistics services, Maritime and Trucking. Documents, small parcels and high-value items are transported via Air and express delivery services (EDS) while the U.S. rail tracking network ensures the transport of heavy cargo and products such as coal and metal ores. Maritime sub-sector, involved in the movement of cargo and passengers by water transports around 78% of U.S. exports. Trucking covers over-the-road transportation of cargo along short and medium distance.
The sector raises serious threat of climate disruption by emitting over one-quarter of total U.S. greenhouse gas. The electric power sector is the largest source of greenhouse gas emissions in the United States. The Obama administration U.S. DOT (U.S Department of Transportation) has focused on climate change challenge and coined multiple strategies to lower greenhouse gas emissions. However by experimenting technical improvements in vehicles and reasonable government policies to enhance vehicle efficiency, energy consumption in the transportation sector could be successfully reduced.
