Transportation represents a large portion – about 29 percent – of U.S. emissions, and the share has been rising in recent years. Rail proponents often argue that investment in trains and public transportation is a key part of making transportation cleaner, and indeed, the Green New Deal calls for greatly expanding high-speed rail.
I’m a scholar of rail, and it’s clear to me that the quickest way to decrease greenhouse gases from transportation is to travel by train and move goods by rail instead of on the road or by air.
To explain why, it’s worth comparing rail to other modes of transportation on energy consumption and emissions, and to look at some of the developments that can make rail more widely used in the U.S. and less reliant on fossil fuels.
Energy and emissions profiles
Transportation by rail is a major part of the transportation system in most countries, including in the U.S., which has the longest freight railway system in the world with approximately 140,000 miles. Rail passenger services are essential in many areas, primarily in population centers such as New York and Chicago, and intercity rail has a significant market share in some corridors, such as the Northeast. Rail also offers long-distance routes connecting many smaller communities with each other and the large metropolitan areas in the country.
