KATHMANDU (TIP): Climbers scaling Mount Everest will have to bring back eight kilograms (17.6 pounds) of garbage under new rules designed to clean up the world’s highest peak, a Nepalese official said on Monday.

The rule, one of several new measures for mountaineering in the Himalayan nation, will apply to climbers ascending beyond Everest’s base camp from April onwards, said tourism ministry official Madhusudan Burlakoti. “The government has decided in order to clean up Mount Everest, each member of an expedition must bring back at least eight kilos of garbage, apart from their own trash,” he said.

Burlakoti said authorities would take legal action against climbers who failed to comply with the new rule, although it was unclear whether this would involve a fine or other penalty. Decades of mountaineering have taken a toll on the peak, which is strewn with rubbish from past expeditions, including oxygen cylinders, human waste and even climbers’ bodies, which do not decompose in the extreme cold. Expeditions will have to submit their trash to an office to be set up next month at base camp. It will also offer medical aid and resolve conflicts, after a brawl between European climbers and local guides last year.
