In brief
Nepal's government has officially discontinued a deposit scheme that required climbers to return with a minimum amount of waste from Mount Everest. Initially implemented to combat the significant litter problem, including around 50 tonnes of waste, officials acknowledged that the program failed to effectively minimize garbage, particularly at higher camps. A new initiative focusing on a non-refundable clean-up fee is set to replace the flawed system.
A scheme to encourage climbers to bring their waste down from Mount Everest is being scrapped - with Nepalese authorities telling the BBC it has been a failure.
Climbers had been required to pay a deposit of $4,000 (£2964), which they would only get back if they brought at least 8kg (18lbs) of waste back down with them.
It was hoped it would begin to tackle the rubbish problem on the world's highest peak, which is estimated to be covered in some 50 tonnes of waste.
But after 11 years - and with the rubbish still piling up - the scheme is being shelved because it 'failed to show a tangible result'.
Himal Gautam, director at the tourism department, told the BBC that not only had the garbage issue 'not gone away', but the deposit scheme itself had 'become an administrative burden'.
Tourism ministry and mountaineering department officials told the BBC most of the deposit money had been refunded over the years - which should mean most climbers brought back their trash.
But the scheme is said to have failed because the rubbish climbers have brought back is usually from lower camps - not the higher camps where the garbage problem is worst.
From higher camps, people tend to bring back oxygen bottles only, said Tshering Sherpa, chief executive officer of the Sagarmatha Pollution Control Committee, which runs an Everest checkpoint.
Other things like tents and cans and boxes of packed foods and drinks are mostly left behind there, that is why we can see so much of waste piling up.
Nepalese authorities are hoping a new scheme will be more effective.
Under the changed rule, officials said, a non-refundable clean-up fee from climbers will be used to set up a checkpoint at Camp Two and also deploy mountain rangers who will keep going to the higher parts of the mountain to make sure climbers bring down their trash.
Tourism ministry officials said it will most probably be $4,000 per climber - the same amount as deposit money - and will come into effect once passed by the parliament.
The non-refundable fee will form part of a recently introduced five-year mountain clean-up action plan, with Jaynarayan Acarya, spokesperson at the ministry of tourism, saying it was designed to immediately address the pressing problem of waste on our mountains.
Although there has been no study quantifying the waste on Everest, it is estimated there are tons of it including human excrement which does not decay on the higher part of the mountain because of freezing temperatures.
The growing number of climbers each year, averaging around 400 with many more supporting staff, has been a growing concern for mountaineering sustainability.
