All domestic plane journeys in Britain should be banned and passengers told to take a train. So says the Campaign for Better Transport in its contribution to the climate emergency debate. Planes emit six times more CO2 per passenger mile than trains. The trouble is that plane tickets tend to be half the price of train ones. So tax planes, and subsidize trains.
So far, so simple. Planes are bad, trains are good. But trains will always be more expensive to run than planes over long distances.
