There are calls for festival-goers to be charged a deposit for pitching a tent.
It comes from the environmental group 'Clean up Britain' after a sea of rubbish was left behind at a number of events in the UK over the summer.
The Telegraph reports the group's proposing a £25 (€27.50) deposit on all camping tickets, which would be returned only if tents are taken home.
The issue of tents being left at campsites has become one of the major concerns for those promoting green policies at summer festivals.
During last week's Reading & Leeds festival in the UK, one of the headline acts - Twenty One Pilots - also took the opportunity to urge festival-goers to take their tents home with them:

Ahead of Electric Picnic this weekend, there are suggestions that a tent deposit scheme could be introduced here.
Oisin Coghlan from Friends of the Earth believes it's a good idea.
Speaking on Newstalk Breakfast, he observed: "I think it's an idea well worth looking at - in fact, we talked about something similar with the organisers of the Electric Picnic festival.
"They haven't taken it up yet, because I think they would regard it as an administrative burden."
Mr Coghlan also noted there was a precedent for deposits, explaining: "We demonstrated at the festival that the idea of a deposit and return scheme works, because as you may know they put a 20 cent deposit on plastic glasses.
"Now, it's a leap from glasses to tents... but when they did that a few years ago - and we were running the return stalls for them - it had a massive effect. What was just waste suddenly became a currency, so everyone picked up their plastic glasses, brought them back and got their money back."
