Madonna is perceived to be the least green act on the bill at London's Live Earth show, according to a survey.
James Blunt, Beastie Boys, Red Hot Chili Peppers and the Black Eyed Peas are also seen by the public as lacking in environmental crudentials.
But it's Madonna who heads the list. The star is said to demand her toilet seat be changed daily and she is known for her extensive air miles, most recently to and from Africa to adopt her new son David.
Saturday’s Wembley concert is one of several taking place around the world to highlight the need to stop global warming.
David Kuo of fool.co.uk, which carried out the survey of 674 people, said: “Although none of us really know for sure how green celebrities really are, public perception plays an important part.
“Live Earth will go some way to help, but caring for the environment goes beyond exercising vocal chords, rapping and crooning. Wouldn’t it be refreshing if all the artists turned up to Live Earth on their bicycles?”
Several bands have criticied Live Earth for being detrimental to the fight against climate change, with Muse singer Matt Bellamy describing the event as "private jets for climate change".
But organisers claim the global shows will have wider implications by encouraging individuals to do their bit for the environment, including simple ways to minimise their own impact.

2. James Blunt
3. Paolo Nutini
1. Beastie Boys
