Mt Everest's climbing season has begun with new rules that require climbers to bring down their personal garbage, and more security officials at the mountain's base camp to help climbers.

Tourism Ministry official Maddhu Sudan Burlakoti said individual climbers going beyond the base camp will be required to bring down at least eight kilograms of their personal garbage and hand it over to officials stationed there.

It is in the latest attempt from the Nepalese government to clean up the world's highest mountain, which draws hundreds of Western climbers and a steady income for the local and national economy, and produces lots of garbage. Until now, climbing teams were asked to bring down their rubbish or risk losing a $US4,000 ($A4,495) deposit - which wasn't very effective as this wasn't widely enforced.

More than 4000 climbers have scaled the 8,850-metre summit since it was conquered in 1953 by Edmund Hillary and his Sherpa guide Tenzing Norgay. Over the years, climbers have left tonnes of garbage on the slopes on the mountain, and some have called it the "world's highest garbage dump."

Burlakoti said officials posted at the base camp would check climbers to make sure that each brings down food wrappings, tents, ropes, clothes, crampons, pegs and gas cans. It was not clear how climbers failing to comply would be punished.

The government is also opening up a contact office tent at the base camp with officials stationed there throughout the spring climbing season that begins in March and ends in May. They will offer help to climbers and resolve any problems between climbers and monitor the garbage situation.

Last year, a brawl between Western climbers and their Nepalese guides on the mountain sparked safety concerns.

Nepal officials say the rules will protect the environment, better manage climbers and increase their safety, especially as their numbers grow.

Nepal has eight of the 14 highest mountains in the world.
