Eco-activist Sting has been criticised by environmental campaigners - for creating a massive carbon footprint with his band The Police at the Live Earth concert. 
The group reformed to tour last year, and made an appearance at the Al Gore-organised event in the summer which aimed to battle climate change.
But The Police have been singled out as the worst offenders in the music industry - beaten by more eco-friendly acts such as rockers Babyshambles and Radiohead, who were deemed the most green band by NME magazine.
John Buckley, of Carbonfootprint.com, says, "At Live Earth in New Jersey where the Police played, the biggest emissions weren't from the concert, it was the fans."
