Ryanair pulls on green jersey as airline's flyers given option to buy carbon offsets
Ryanair will now allow customers to buy "voluntary" carbon offsets to ease their consciences when flying.
"The funds that are raised from these voluntary guest donations will be distributed annually to environmental charities and NGO's [non-governmental organisations] as selected by our people," it said.
In a 2007 interview CEO Michael O'Leary said: "I don't think the advice of a bunch of UN scientists should be taken as gospel truth.
"Human breathing is one of the biggest problems as far as I can see, so why don't the environmentalists just shoot all the humans?"
