Single-use plastic bottles will be banned from this year's Glastonbury Festival for the first time in a bid to reduce plastic consumption.
More than a million single-use plastic bottles were sold at the last festival in 2017.
The announcement - made on the festival's website - said plastic bottles will no longer be available to buy and will not be available in dressing rooms, catering, production and backstage areas.
Organisers are encouraging festival-goers to take reusable bottles and refill them with the "hundreds" of free water taps on site.
They are also tripling the number of WaterAid kiosks on the ground.
Emily Eavis said: "It's paramount for our planet that we all reduce our plastic consumption, and I'm thrilled that, together, we'll be able to prevent over a million single-use plastic bottles from being used at this year's Festival.
"I really hope that everyone - from ticket-holder to headliner - will leave Worthy Farm this year knowing that even small, everyday changes can make a real difference. It's now or never."
People will still be allowed to bring plastic bottles to the 2019 festival, but organisers want guests to "join the effort by bringing as little single-use plastic as possible."
Glastonbury Festival will return to Somerset's Worthy Farm on June 26.
