The analysis concludes that the carbon footprint of high speed rail including operation, track construction and rolling stock construction is about 14 to 16 times less than transport by private car or airplane.

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 results reveal that HSR can decrease carbon emissions by an average of 2.3 percent.

High-Speed Rail is the Solution. Shifting drivers to trains creates fewer greenhouse gas emissions, since trains are far more energy efficient than cars (or 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.

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 trains, in particular, were rendered obsolete in 1958, when Boeing introduced the 707 jetliner, which was twice as fast as the fastest trains today. Slower than flying, less convenient than driving, and more expensive than either one. Aside from speed, what makes high-?speed rail obsolete is its high cost.

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 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.

Most CO2 emissions from high-speed rail are a result of deforestation related to the construction of new railway lines.

Implementing high-speed rail will keep billions of dollars in the U.S. economy by decreasing the amount of oil that the U.S. consumes. 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.

Implementing high-speed rail (HSR) will provide Americans with more transportation choices. It will also make sure that America remains an economic engine, and meets the environmental and energy challenges of this century.

The California HSR, for example, will remove 12 billion pounds of carbon dioxide per year by 2030 because it uses electricity generated from wind, solar, and other renewable resources. In addition, California's HSR will save 12.7 million barrels of oil by 2030.

Build costs in the UK are higher. This is partly because we have higher costs associated with design. It is also because our sector is particularly reliant on subcontractors. Little more than an eighth of the UK construction workforce is permanently employed, according to the Construction Products Association.
