Carbon Emissions
In 2005, Amtrak's carbon dioxide equivalent emissions per passenger kilometre were 0.116 kg. For comparison, this is similar to Canada's Via Rail or a car with two people, about twice as high as the UK rail average, about four times the average US motorcoach, and about eight times a Finnish electric intercity train or fully loaded fifty-seat coach. It is, however, about two thirds of the raw CO2-equivalent emissions of a long-distance domestic flight.
