The Khumbu Bijuli Company (KBC) has been playing a pivotal role in conservation of high altitude forests not only by providing clean and alternative source of energy, but also directly through reforestation programs.
KBC built a water treatment plant and set up a sewage system in Namche Bazaar in 1999 with technical support from Salzburg AG and joint contributions from Eco Himal, KBC, Namche VDC and local users.
