Is high-speed rail more environmentally friendly than planes?
Eurostar estimates that a one-way train trip emits around 10 pounds (4.5 kilograms) of CO2 per passenger, making it a much more sustainable choice compared to flying.

Amid all the talk about reducing aviation emissions, modal shift does not get a lot of air time. However, the spread of high-speed rail (HSR) over the past decade has made trains a competitive, low-carbon alternative to short-haul flights.
However, as an energy researcher, my decision was motivated by the fact that trains, whether for cargo or passengers, pollute much less than airplanes, sometimes by as much as 73%, and they are more easily electrified than planes.
High-Speed Rail Helps Reduce Carbon EmissionsIn the United States, transportation currently generates 29% of carbon emissions – a driving force in climate change. No other mode of travel has the flexibility to serve diverse, dispersed markets and spur a massive shift from driving.
Trains. Besides walking and biking, traveling by train remains one of the greenest and most environment-friendly options when getting around. Regardless if electric or diesel-powered, trains emit between 66 and 75 percent fewer carbon emissions when compared to cars and airplanes.
Building high-speed rail systems require steel and concrete, the manufacturing of which typically generates greenhouse gases. Trucks, bulldozers, and other construction site equipment also consume energy. Thus, during their long construction phases, high-speed rail projects add greenhouse gases.
The International Council on Clean Transportation identified that short-haul flights between dense urban centers comprise a quarter of domestic US air travel. For these flights segments, electric high-speed rail could reduce emissions (compared to air travel) by 23%. Downtown Limburg, Germany.
High-speed rail is generally regarded as the pinnacle of attractive and green transportation. But all too often, it makes train travel more expensive and less flexible. In the end, costly high-speed lines may just push more people into cars.
If you take the train, then you'll cut carbon dioxide (CO2) by half compared to the plane. A key reason is that the train (or the diesel bus) may be a big carbon emitter, but it's designed to carry a lot of passengers, so the per capita emissions are a lot lower.
So, if you're traveling with three or more people, driving is the better option, and here's why: Three people on the cross-country flight would account for 1.86 tons of carbon emissions (0.62 tons of CO2 x 3), compared to the total 1.26 tons of carbon the vehicle would produce (ignoring that the extra weight would ...
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.

Trains Emit Less CO2 Than Other Transport MethodsRecently developed hydrogen-powered trains are the most eco-friendly trains in the world, emitting nothing except steam as a by-product and creating very little noise.
High Speed Rail is the world's safest form of transportation proven by decades of operations all around the world. Japan was the first nation to build high speed rail in 1964, and has since transported 10 billion passengers without a single injury or fatality!
According to the International Association of Railways (UIC), high-speed rail is eight times more energy efficient than airplanes and four times more efficient than automobile use. It will also decrease greenhouse gas emissions and improve air quality.
