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.
