Are trains more sustainable?

One of the biggest environmental benefits of trains is that they consume far less energy than other types of transport. It takes a huge amount of fuel to get a plane carrying hundreds of people airborne, whereas trains are streamlined, require much less energy to move, and are increasingly able to run on electricity.

Based on the study's fuel efficiency and carbon dioxide emission data, the most sustainable mode of traveling in the U.S. is via intercity bus, followed by trains. Intercity buses use 280.1 passenger miles/gallon, while trains use 79.8 passenger miles/gallon.

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.

HSR is electrically powered and can run 100% on clean, safe renewable energy. One high speed train powered by the wind can carry more passengers than 9 oil-burning, carbon-spewing airplanes!

MORE DETAILS

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.

MORE DETAILS

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%.

MORE DETAILS

Trains create pollution; however, it is important to note that on a passenger level rail is one of the lowest impact public transport methods, in addition the carbon footprint intensity of rail continues to decrease.

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.

MORE DETAILS

Air travel is convenient and can transport large numbers of passengers, but it has a high environmental impact due to carbon emissions and fuel needs. Gas-consuming vehicles provide convenience and flexibility but have high carbon emissions and contribute to traffic.
