The Telegraph says: “The campaign to stop global warming now has an A-list of supporters from the world of showbiz.

Leonardo DiCaprio

The Prius-driving Hollywood star is the leading climate change celebrity.

DiCaprio has received praise from environmental groups for opting to fly on commercial flights instead of chartering private jets. His actions have inspired other celebrities, such as Orlando Bloom and Penelope Cruz. Co-wrote, co-produced and narrated the film 11th Hour and cites global warming as “the number one environmental challenge.”

Thom Yorke

Lead singer of critically acclaimed rock outfit Radiohead, is outspoken on various contemporary political and social issues. Yorke made headlines for refusing former prime minister Tony Blair’s request to meet him to discuss climate change, declaring Blair had “no environmental credentials.”

Yorke has subsequently been critical of his own energy use. He has said the music industry’s use of air transport is dangerous and unsustainable, and that he would consider not touring if new carbon emissions standards do not force the situation to improve.

Radiohead commissioned a study by the group Best Foot Forward which the band claims helped them choose venues and transport methods that will greatly reduce the carbon expended on their 2008 tour. The band also made use of a new low-energy LED lighting system and encouraged festivals to offer reusable plastics.

Cate Blanchett

Australian actress Blanchett has been involved in promoting tough environmental policies down under in Australia for many years now, through lobby group whoonearthcares.

Most recently, the actress appeared in Copenhagen in May of this year at the World Business Summit on Climate Change. The actress addressed business leaders, urging them to decrease their carbon emissions and increase sustainable practices.

“Political failure at Copenhagen in December is quite simply unacceptable and this powerful room must play a major role in preventing this failure,” she said.

Sting

An early convert to the environmentalist cause, particularly the Save the Rainforest movement. A species of Colombian tree frog, Dendropsophus stingi, was named after him in recognition.

Though Sting’s personal carbon footprint regularly comes under scrutiny, the famous singer is backing Prince Charles’ Rainforests Project — which seeks to limit deforestation and buy the world time to move to a low-carbon economy.

Ahead of the Copenhagen Talks, Sting has lent his iconic “Message in a Bottle” song to the campaign — sending a different kind of SOS to the world

Global Cool, an environmental charity which has enlisted celebrities such as KT Tunstall to help to make saving energy an “aspirational lifestyle”, gives them all “carbon coaching” to help them to reduce their footprints. It aims to encourage a billion people worldwide to take steps to reduce their carbon emissions by one ton per year.

Hollywood heart-throb Josh Hartnett is a Prius-driving vegetarian; has backed also Global Cool since its inception

Miley Cyrus

The frothy teen-queen might not be immediately associated with the great issues of the day but on her recent album she produced the consciousness-raising track, Wake Up America.

The chorus went: Wake up America/We’re all in this together/It’s our home, so let’s take care of it/You know that you want to You know that you got to/Wake up America/Tomorrow becomes a new day/And everything you do matters/Yeah, everything you do matters in some way.”
