Biogas Project, Cambodia

This project contributes to multiple UN Sustainable Development Goals, delivering measurable environmental and social outcomes.

Project details

In many rural parts of Cambodia, communities lack access to modern energy sources such as electricity and gas. As a result, households often rely on open wood fires for cooking, a practice that poses serious health risks, contributes to environmental degradation, and demands significant time and effort from families, particularly women and children.

Biogas systems offer a practical and sustainable solution. A typical household biogas installation can provide sufficient clean energy for daily cooking and basic lighting needs. On average, the system requires organic input from around two cows to generate enough biogas, offering a cost-effective, healthier, and more environmentally friendly alternative to traditional fuels.

About the project

This project brings clean, reliable energy to rural households in Cambodia by making biogas installations accessible and affordable. Installed directly on the recipient’s property by trained local builders, each system processes cow dung in an anaerobic digester to produce biogas. The resulting gas is piped into homes where it is used for cooking and lighting. The remaining by-product, known as bio-slurry, is a nutrient-rich organic fertiliser that enhances soil health. Some families have also connected biogas toilets to their systems, enabling the conversion of human waste into additional biogas, further improving hygiene and resource efficiency.

The initiative is led by the Hivos Foundation in collaboration with SNV Netherlands Development Organisation, under the National Biodigester Programme (NBP). Anthesis supports the project by providing technical expertise and contributing to its expansion through the purchase of Gold Standard-certified carbon credits.

In addition to reducing greenhouse gas emissions, the project stimulates local economies. Entrepreneurs are trained to build and maintain the biogas systems, creating employment opportunities and supporting the development of sustainable energy markets. This approach ensures that clean energy solutions continue to reach low-income households and small businesses across Cambodia.

Quality criteria

All Anthesis-supported carbon removal projects undergo independent verification to confirm permanent carbon storage and measurable environmental benefits. Projects must demonstrate alignment with UN SDGs 12, 13, and 15, promote soil and ecosystem health, and deliver robust climate and nature outcomes.

Through rigorous auditing, monitoring, and adherence to international standards, Anthesis ensures all projects provide credible, lasting impact for both climate and local communities.
