(Community Development Carbon Fund)

UNFCCC Reference No.: 2221

Installation of biogas burners in households

Project Description: The project aims to install a bundle of 33,000 household-level bio-digesters in a mountainous and poor area of the Hubei Province in China. These activities will recover methane from biogas digesters with pig manure as fermentation material and utilize the generated biogas to displace fossil fuel for household cooking and heating. In addition, the recovery and utilization of biogas from digested slurry in a biogas digester reduced CH4 emission from the slurry that would otherwise have been stored in a deep pit.  Annual emission reductions are estimated to be 58,444 tCO2e over a 10 year crediting period, of which the CDCF would purchase 370,000 CERs.

Current Context: China’s southwest Hubei Province is a poor rural, mountainous area where the main economic activity is in agriculture. The project area covers 625 villages in 81 townships within 8 counties (Enshi, Lichuan, Jianshi, Badong, Xuan’en, Xianfeng, Laifeng and Hefeng). In determining households for installing the system, priority has been given poor and relatively poor households.

Community Benefits: Aside from reducing green house gas emissions, the project is an example of how the CDM can deliver direct co-benefits for small rural communities. Thanks to the project each household benefits from the improvement of its toilet facilities and pig pens, kitchen renovations as well as the installation of a gas burner. More specifically the replacement of traditional coal stoves with the biogas burners reduces the use coal, household energy costs and indoor air pollution. Households thus benefit from reduced incidence of respiratory diseases and eye ailments caused by coal burning. Moreover, improved household waste and manure management practices help to decrease ground and surface water contamination, the proliferation of zoonotic diseases and noxious odors caused by animal manure.

Thus Co-benefits include improving indoor air quality and local air quality through avoidance of burning coal and other fuels, and provision of better sanitary handling of domestic and livestock wastes, helping to prevent the spread of disease.  This all helps improve the health of residents, and assist with socio-economic aspects such as a reduction in the cost of buying fuel and time spent collecting firewood, freeing up time for other activities such as education of children, tending crops, and social activities.

The project is featured on the UNFCCC website as an exemplary project generating co-benefits:
