Unless extenuating circumstances prevail, there are few excuses for not removing all your non-human waste. If extenuating circumstances insist that disposal or burial on-site is the only option, record the waste details and position. Subsequent expeditions may be able to remove it. Do not ignore other people's waste, make every attempt to remove it as well as your own. Ensure that removed waste reaches its destination.
Porters are likely to dump their load as soon as they realise what they are carrying.
Dispose of your waste responsibly when you reach a suitable destination. Above all, be aware of the environmental consequences of your actions. Make every attempt to minimise your impact and remove your expedition waste from the mountains. The BMC Environmental Guidelines have been adopted by the UIAA and were endorsed at the 6th World Wilderness Congress where they were distributed to delegates.
