How much co2 does a train save?

If you can't walk or cycle, then public transport is usually your best option. Trains are particularly low-carbon ways to travel. Taking a train instead of a car for medium-length distances would cut your emissions by around 80%. Using a train instead of a domestic flight would reduce your emissions by around 86%.

Compared to flying, using the train emits on average six times less GHG emissions.

Another reason why railroad transport is better than road travel is the fuel efficiency they offer compared to hiring vehicles. Railways can consume up to nine times less fuel for every ton they carry for a kilometer, making trucks fuel inefficient compared to railroad transport.

National rail emits around 35 grams per kilometer. A domestic flight emits 246 grams. So the footprint of taking the train is around 14% of a flight: [ 35 / 246 * 100 = 14%].

Finally, the plane is the most polluting means of transport and the one that generates the most greenhouse emissions.

Train travel is the most ecologically friendly option, aside from walking or bicycling. They emit 66-75% less carbon emissions than other forms of transportation, even if they're electric.

Aviation is responsible for between 2pc and 3pc of global carbon emissions. And Ms Thunberg continues to refuse to fly because of the impact on the environment.

Greenhouse gas (GHG) emissions are directly related to fuel consumption. According to EPA data, freight railroads account for just 0.5% of total U.S. GHG emissions and just 1.7% of transportation-related GHG emissions. Moving freight by rail instead of truck lowers GHG emissions by up to 75%, on average.

Trains are nearly always the winning option over moderate-to-long distances; If travelling internationally, going by train or boat is lower-carbon than flying; Electric vehicles are nearly always lower-carbon than petrol or diesel cars.

These massive, track-mounted vehicles, which use a diesel generator to power electric motors and move rail cars carrying cargo or passengers, are major polluters, responsible for a growing share of the emissions that increase cancer risk, shorten lives and worsen smog across California.

From a climate perspective, Amtrak outperforms planes, but not by as much as it could. Outside the Northeast, Amtrak still runs on diesel, and while taking Amtrak is far less polluting than flying for short trips, for longer trips of over 1,000 miles or so, direct flights release slightly less CO2 per person.

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.

It is very true that when moving on flat ground in a straight line, trains on steel wheels and rails are the most efficient form of transportation. Rolling on steel rails reduces rolling resistance and traveling at slow speeds (compared to jet aircraft) reduced the force of air resistance.
