Hivos Carbon Credits website



In 2006, the Cambodian Ministry of Agriculture, Forestry and Fisheries (MAFF) and SNV Netherlands Development Organization joined to establish the Cambodian National Biogas Programme (NBP) to create an indigenous, sustainable energy source in Cambodia by utilizing biogas. Domestic bio digesters provide a way for individual households with lifestock to reduce their dependence on polluting firewood and expensive fossil fuels for cooking and lighting. Hivos supports the programme by facilitating the monitoring and verification of greenhouse gas emission reductions and marketing its carbon credits.

A clean renewable fuel

The benefits of biogas are two-fold: it provides a source of clean renewable fuel and an organic fertilizer (bioslurry) to be used to improve crop yields, thus leading to greater produce income. Cooking on biogas is fast and smokeless. It eliminates the need to spend time on collecting firewood and improves the health of users, especially women and children. In addition, the programme offers extensive vocational training and skills development for biogas masons and creates employment opportunities to a wide range of stakeholders across the supply chain.

Creating a biogas sector

The NBP programme aims to develop a self-sustaining, market driven national domestic biodigester sector. It is establishing independent enterprises in rural areas and building their capacity on promotion, construction, internal quality control and aftersales services. By the end of 2017, over 26,500 biodigesters have been constructed in fifteen different provinces. An important success factor is a special biogas loan made available through three nationally operating microfinance institutions. Over 70% of households take up this loan to finance their bio digester. They generally pay it back within two years.
