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.
