Actress and environmental campaigner Greta Scacchi has been a great supporter of our climate change campaign.
In 2007, she spoke from the stage at the Cut the Carbon rally in Cardiff, and in 2009, she met NASA's James Hansen and the Bishop of Liverpool in Coventry to protest about the advance of E.ON's plans for coal-fuelled power stations.
She also addressed Christian Aid Fringe meetings at both the Labour and Conservative party conferences, where she met Ed Miliband and current Development Secretary Andrew Mitchell.
