Rail has one of the lowest levels of greenhouse gas emissions per passenger kilometre of any mode of land transport.

In the UK overland rail has less than a quarter the CO2e emissions per passenger km of the average car. Levels will vary in other areas depending on fuel type and efficiency. In France where much of the network is fuelled by nuclear electricity, rail travel has a very low CO2e impact.

Take the train for significant savings in carbon over car and flight.
