Nepal will be implementing a ban on single-use plastics in the area surrounding Mount Everest next year.

According to CNN, the ban, which will take effect in January, is an effort by authorities to decrease the amount of trash left in the region by visitors.

Ganesh Ghimire, who serves as chief administrative officer of Khumbu Pasang Lhamu rural municipality, told CNN that officials “are consulting with all sides about what can be done about plastic water bottles.”

“We will soon find a solution for that,” he continued.

Officials have also not yet reportedly decided on penalties for those who violate the new ban. 

Ghimire said the region has roughly 150,000 tourists annually. According to the BBC, 11 tons of trash was collected from Mount Everest by authorities in a recent cleanup.

The ban follows a vote made the European Parliament in March to approve a measure that seeks to ban single-use plastic items by 2021.

Months after, Canadian Prime Minister Justin Trudeau announced that Canada too was also aiming to ban single-use plastics within the same time frame.
