Do high speed rails reduce carbon emissions?

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 trains run on electricity instead of diesel fuel. Because much of the world's electricity is still generated at fossil fuel burning power plants, high speed trains do contribute to carbon emissions, however the climate impact of one train is significantly less than that of many personal vehicles.

Dedicated Infrastructure Is Wasted But high-speed rail lines can only move people, making them far less cost-effective. To save energy, high-speed rail cars are far lighter than conventional rail cars and cannot be safely used on the same tracks as frequent heavy freight trains.

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.

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.

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.

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%.
