Hivos Carbon Credits website



Farmers represent 80 percent of the rural poor population in Tanzania. They depend on agriculture, mainly mixed farming, by rearing livestock and cultivating land. A majority of them relies on polluting firewood and expensive fossil fuel as their main energy source for cooking and lighting. The goal of the Tanzania Domestic Biogas Programme (TDBP), implemented by CAMARTEC is the promotion, dissemination and increased adoption of domestic biogas as a local sustainable energy source. Cooking on biogas is fast and smokeless. It improves indoor air quality, which in turn has positive health impacts especially on women and children.

The TDBP programme started in 2009, and about 6,500 biodigesters were installed from 2009 to 2017. The programme works in close collaboration with an extensive construction partner network. This has made it possible to reach disparate regions and rural communities. The carbon finance revenues are used to provide extension, maintenance and repair services to the users who installed digesters.

Initially, most Tanzanian farmers take an interest in biogas primarily as a source of cheap and clean fuel. The programme builds the capacity of biodigester users to benefit from the full range of biogas technology through various training sessions. Use of bioslurry has improved their agriculture production and provided savings thanks to reduced purchases of chemical fertilizers, thereby increasing household incomes levels.

In the sales of Tanzania carbon credits, Hivos partners with Climate Neutral Group.
