Environmental effects of rail
Script error: No such module "AfC submission catcheck". Rail transport is an emitter of carbon dioxide (CO2) which is one of the main greenhouse gases. It is emitted either directly by a diesel locomotive, or indirectly by the production of electricity necessary for the locomotives.
Energy vector[edit]
According to the International Energy Agency, in 2004 the transport sector accounted for 26% of global energy consumption, or 23% of global greenhouse gas emissions.[1] In 2000, rail transport consumed 1.19 exajoules (1018 joule), that is 1.5% of the energy consumed for transport worldwide.[2]
This energy is mainly traction energy which is either electric or diesel. Coal, which was still widely used in some developing countries until the early 2000s, is now reserved for historic or tourist vehicles.[3]
CO2 emissions from rail transport vary from one country to another depending on whether or not its rail infrastructure is more or less electrified and on the energy mix used to produce the electricity.
In general, electricity is largely dominant in rail transport in Europe and Japan, while in North America it is diesel.
