Promises, promises - festival stars make climate pledges
Artists performing at Europe's biggest free festival have pledged to help tackle climate change including by drinking low carbon local beer.
Sheffield's Tramlines Festival drew crowds of 125,000 revellers, all encouraged to consider their environmental credentials.
Artists, including Tinchy Stryder, the Hoosiers and Echo and the Bunnymen, made a series of small, carefully considered climate pledges.
Some performers said they would become vegetarian or cut down on red meat with others showing an awareness of wasted electricity from sound systems and recording equipment.
A number highlighted the excesses of the fashion industry and said they would make an effort to wear vintage clothes.
Organisers were careful to cut the environmental impact of the weekend event, with the help of city campaign Sheffield Is My Planet.
As well as recycling 2.2 tonnes of plastic waste, a solar powered silent disco on Sheffield's Devonshire Green proved popular with visitors.
Those pledges in full:
Sheffield legend Richard Hawley - "I promise to go veggie at festivals and gigs to cut down on red meat and I'll also wear vintage clothes."
Chart topper Tinchy Stryder - "I promise to switch off the air con in hotel rooms when I'm on tour."
Pop star Dane Bowers - "I promise to switch off all unused equipment when I'm in the recording studio and switch off the air con in hotel rooms when I'm on tour."
