Turns out that trains aren\’t all that non-polluting after all.
Defra also recalculated its figures for rail travel. It concluded that the average figure for \”national rail\” travel was 60.2 gCO2/pkm.
Coaches are much better.
Defra\’s new figure for coaches is 29.0 gCO2/pkm – twice as efficient as going by train and almost six times as efficient as flying.
But, here\’s the kicker. VW Polo diesel. 119 g /km. 4 people in it. 30 g/pkm.
So, we definitely don\’t want to be taking the train then and as a car goes where you actually want to go and a coach does not then cars all the way it is then.
There are good arguments for train systems in some places (London commuting for example) but it doesn\’t look like there\’s much of a carbon emissions one for trains elsewhere.
