U2 have hit back at critics of their tour’s carbon footprint.
Environmentalists recently argued that the gigs have the same effect on the world as flying the 90,000 fans with tickets to the Wembley leg of their tour to Dublin.
Other critics claimed that U2 will emit three times more carbon than Madonna did during her 2006 string of dates.
But The Edge told BBC 6Music: “I think it’s probably unfair to single out rock ‘n’ roll.
“There’s many other things that are in the same category but as it happens we have a programme to offset whatever carbon footprint we have.”
Environmentalists and local residents joined together in July to protest outside Dublin’s Croke Park stadium about the tour.
