According to the 2021 U.S. Department of Energy Data Book, Amtrak is 46% more energy efficient than traveling by car and 34% more energy efficient than domestic air travel.
“When you take into account the production of railroad equipment and tracks, all of that is very carbon intensive as well,” says Hamilton. “Take the entire picture and trains are actually more polluting than the road buses, even though buses all run with dirty diesel fuel.”
If we take an overall view of the transport sector, 71% of transportation related carbon emissions come from road users, whereas only 1.8% of emissions stem from rail travel. So in absolute terms, trains are responsible for a lot less emissions than cars.
Public transportation gets people where they're going while emitting far fewer climate-warming greenhouse gases than private cars. The reason is simple efficiency: while cars usually carry just one or two people at a time, a bus can carry 50 or more, and a train in a large city may carry thousands.
There are many reasons for this. There is limited service between cities (Amtrak says it runs 300 trains with about 87,000 passengers per day), freight is often prioritized over passenger service in the U.S., and trains and facilities are often outdated.
We have lots of passenger trains in the USA, the vast majority are commuter trains on the East Coast, and some around other major cities. If you mean long distance, cross country passenger trains then the answer is simple, the distance is too great, and there are far better options for travel than taking the train.
The cleanest modes of transportation are walking and biking. Walking to and from the store will not only get you closer to your daily step goal, it will not contribute to air pollution. If you biked one kilometer to the store, your bike's emissions score would be 8.
