According to International Union of Railways (UIC) data, high-speed rail is more than four times as energy efficient as driving in cars and nearly nine times more efficient than flying.

Compared to flying, using the train emits on average six times less GHG emissions.
High Speed Rail Association. The International Union of Railways showed that even commuter trains are far more efficient than buses, cars, and planes, and they produce far less carbon dioxide pollution than cars and planes. A 2021 study showed China's stunning rails reduced vehicle-produced air pollution.
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!
HSR reduces traffic congestion and gaseous waste emissions, as well as environmental pollution, by replacing traditional transportation (Anderson, 2014). According to the study of Chen et al. (2016), HSR has a significant and positive effect on environmental degradation.
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.
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%].
Building a national high-speed rail network requires decades of annual appropriations similar to the funding stream that built the interstate highway starting in the Eisenhower administration, said Louis Thompson, a former director of the Federal Railroad Administration and a member of the California High-Speed Rail ...
The US is huge with a low population density. Other than commuter trains near major metropolitan areas, passenger rail is only feasible with high government subsidies. A new high-speed rail system would cost a fortune and benefit very few people.
Trains are a fast, comfortable alternative to cheap flights in Europe, especially when you're visiting multiple destinations. A Eurail Pass gives you unlimited, borderless travel across Europe with just one ticket, so you can go a lot further with your money – and you'll be doing your bit for the planet, too.
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.
Understanding these emission differences can help us travel efficiently without adding to air pollution and climate change. 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 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.
As a solo rider, driving a car wouldn't help lower your emissions — it would be higher than air travel, at 120 pounds of CO2. Though if you had four people in the car, the air pollution you'd emit would fall to just 30 pounds of CO2 per passenger.
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.
HSR is surprisingly fast and can provide high capacity with low operating costs, yet its high infrastructure costs and frequent budget overruns outweigh its advantages. Air travel remains more time-efficient for many US trips and requires far less infrastructure.
Compared with driving, flying, or riding conventional rail, it is the fastest way to travel between two points that are a few hundred miles apart and reduces carbon emissions up to 90 percent. Over time, its energy source is likely to get cleaner as renewables generate a greater share of electricity.
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!
