Tracey Emin's latest work deals with the threat of climate change, but she admits she is a "bad advert" for action on the issue.
Unveiling her embroidered images of flowers, insects and birds for a Royal Academy exhibition on responses to climate change, Emin, 46, said: "I think man makes a major contribution to climate change. We have to slow down. One day a week turn down the energy... saying that, it is really hard to do that when you are living in the 21st century, it's a fast lifestyle."
She admitted: "I'm not a good person. I'm a bad advert. I take too many planes... I keep my heating on all day and night because I get really cold and I'm scared of the dark so I sleep with the light on.
"I do try to make other compromises in other areas of my life. I don't have lots of clothes for example. I'm not contributing to the clothes mountain."
The exhibition also features a shattered diamond made from a polar bear's leg bone, a giant cage-like globe and glass representations of jellyfish, all inspired by climate change.
GSK Contemporary Earth: Art of a Changing World runs at the Royal Academy from tomorrow until 31 January 2010
