The increase in climbing fees is part of a series of measures aimed at reducing pollution and ecological impact on Mount Everest, the highest peak on the planet.

The Nepali government has significantly increased climbing permit fees for Mount Everest or Mount Qomolangma, an official said on Wednesday.

Nepal will increase the permit fees for climbing Mount Everest by more than 35%, making the world’s tallest peak more expensive for mountaineers for the first time in nearly a decade, officials said on Wednesday.
