You may remember that a few weeks ago we ran a story about British Airways emailing the members of its Executive Club (who number in the tens of thousands) asking them to sign a petition supporting the proposed third runway at Heathrow Airport.
In it, BA chairman Willie Walsh made the rather remarkable assertion that the massive increase in traffic wouldn't increase emissions in climate change gases. According to Mr Walsh, the fact that airliners would spend less time queuing for take-off and landing spots would reduce CO2 emissions by 330,000 tonnes a year, a figure which the email implied had been endorsed by the government.
