So BA is running ghost flights, empty planes, so that it can keep its slots at the London airports:
Some of the aircraft are thought to be Boeing 747s, which when full carry between 500 and 600 passengers. Every return flight from London to New York generates about 1.3 tonnes of CO2.
That would be 1.3 tonnes per passenger they\’re not carrying actually.
A spokesman from Greenpeace said: "It\’s pretty outrageous that BA are flying these empty flights half way across the world whilst saying they’re trying to cut down on CO2 emissions.
"They should be setting a leading example. Thousands of tonnes of carbon dioxide are being leaked out needlessly just so they can keep their slots."
"Just so they can keep their slots" is not "needlessly". It might be a need you don\’t understand, it might be a need you don\’t approve of, but it\’s not "no need".
