Mount Everest Waste Volume and the Poop Slide Problem
Mount Everest now hosts a growing volume of human waste from commercial expeditions, with thousands of climbers and guides producing an estimated 12,000 to 14,000 kilograms of feces per climbing season, much of it left in snow pits or deposited on slopes that have become known colloquially as the poop slide. The Nepal government and the Sagarmatha Pollution Control Committee require each climber to bring down a minimum of 8 kilograms of waste, but enforcement remains inconsistent, and climate change is exposing old waste as glaciers retreat, turning sections of the mountain into a visible and persistent sanitation challenge. The issue has drawn attention from mountaineering regulators, environmental groups, and logistics companies that manage base camp infrastructure, including portable toilet systems and waste containers that must be carried down by Sherpa teams and support staff. For a detailed breakdown of the scale and policy responses, see the official Nepal tourism and mountaineering regulatory updates at https://www.tourism.gov.np.
The physical reality of the poop slide on Everest is shaped by high altitude, freezing temperatures, and the movement of ice and snow, which can shift buried waste and expose it during the spring and autumn climbing windows. Helicopter evacuation of waste from higher camps is technically possible but extremely costly, with operators such as Fishtail Air and Air Dynasty charging premium rates for heavy-lift missions that are rarely used for routine waste removal. Most expeditions rely on a combination of blue barrels, portable toilets at base camp, and the requirement that climbers carry down their own human waste from higher camps, a rule that has reduced accumulation at the South Col but has not eliminated the problem on the slopes above. The financial burden of waste management is passed through to climbers via expedition fees, which can range from 30,000 to 100,000 USD per person depending on the operator and the level of support, with a portion of that cost covering logistics, permits, and waste transport.

Climbing Permits, Regulations, and Financial Costs
Nepal charges foreign climbers a permit fee of 11,000 USD per person for the spring season, while the government of Tibet under China sets its own fees and restrictions for the northern route, and both jurisdictions have introduced or tightened rules on waste removal, oxygen use, and climber experience levels in recent years. The Nepal government has required climbers to submit a deposit that is refunded only if they bring down a specified amount of waste, a policy designed to incentivize compliance and reduce the volume of material left on the mountain, including on the steep sections where the poop slide effect concentrates debris. These regulatory changes are part of a broader effort to manage overcrowding, safety risks, and environmental damage, with authorities citing traffic jams, deaths, and media coverage as drivers for stricter oversight of expedition operators and their clients. The financial impact on climbing companies includes not only permit costs but also investments in waste management infrastructure, such as solar-powered toilets at base camp, additional Sherpa support for waste carry-downs, and compliance with new documentation requirements set by the Nepal Mountaineering Association and the Department of Tourism.

The cost of managing Everest waste is a growing line item in expedition budgets, with operators factoring in the labor of Sherpa teams who are paid to carry waste barrels down from higher camps, the purchase and maintenance of portable toilets, and the logistics of transporting full containers to disposal sites in Kathmandu or Namche Bazaar. Some companies have invested in vacuum-seal systems and specialized bags that reduce volume and odor
