MONBIOT: It is becoming morally unacceptable now to fly to go on holiday. The carbon emissions per passenger mile are roughly the same from a plane as they are in a car, but while in a car you might travel 10,000 miles in a year, in a plane you travel 10,000 miles in a day. So individually, by taking a flight, you are doing more damage than you could possibly do by any other means, and your luxury is depriving other people of their necessities.
NEWSWEEK: Have you given up flying?
MONBIOT: The only reason for which I will fly is to campaign on climate change.
