Nepal has banned single-use plastics in the Everest region in a bid to cut down on waste left by climbers.
According to the BBC, the ban will take effect in January 2020, though a penalty has yet been announced for violators.
All plastic drinking bottles and plastics of less than 30 microns in width will be banned.
Trekking companies, airlines and the Nepal Mountaineering Association will work with local officials to enforce the ban.
Authorities recently cleared 11 tonnes of rubbish from Mount Everest.
