In 2012, to relieve capacity pressure, overcrowding on the world's highest mountain was tackled by placing greater restrictions on expeditions to the summit of Mount Everest. The move is a response to growing problems with litter, pollution and recent clashes between Sherpas and Western climbers. But, in an attempt to appease those hoping to conquer the tall peak, the Nepalese government is to open access to five other summits that sit over and develop climbing tourism. Nepal lobbied the International Climbing and Mountaineering Federation (or UIAA) to reclassify five summits (two on Lhotse and three on Kanchenjunga), as standalone eight-thousanders, while Pakistan lobbied for a sixth summit (on Broad Peak). The UIAA initiated in 2012 what it calls the ARUGA project with an aim to see if new -plus could feasibly achieve international recognition. Under that project, Nepal had tabled five new peaks and Pakistan had tabled one. In 2012, the UIAA set up a project group to consider the proposals called the AGURA Project. The six proposed summits for reclassification are subsidiary-summits of existing eight-thousanders, but which are also themselves above and have a prominence above .
