The article reports on the work undertaken by the Biogas Sector Partnership Nepal (BSP Nepal), to replace wood fuel for cooking with clean and efficient biogas from cattle and human waste. This year, BSP Nepal has been honored with the prestigious Ashden Award, worth 30,000 pounds. BSP Nepal was established in 1992. The Netherlands Development Organization in Nepal and, the German Development Bank and the Government of Nepal are giving financial and technical assistance to BSP Nepal. BSP Nepal has already established 140,000 biogas plants in 66 out of the 75 districts in Nepal. Since people now cook on smokeless stoves, biogas has several health benefits. A study of 1200 households in 20 districts revealed that introduction of the biogas plants saved an estimated total of 420 000 tons of wood and reduced carbondioxide emissions by 640 000 tons year. While previous biogas programs in Nepal have failed, BSP Nepal has been very successful due to standardized plant design and stringent quality control.
