Project details

BiogasGet to know the project

With the support from this project, 15,555 biogas digesters have been constructed in rural households in the 20 towns belonging to the city of Haikou in Hainan province. The project helped farmers to build methane digesters where organic matter including manure and wastes are decayed anaerobically. Every household has an average of 2.5 pigs, the manure of which is fed into the digester with a volume of eight cubic metres, producing enough biogas to meet one household's thermal energy demand.

Before the project started, the farmers stored the manure in deep pits with anaerobic conditions for more than three months, which caused large amounts of methane emissions to the atmosphere. The project helps avoid these methane emissions, but also CO₂ from cooking. The biogas produced in the digesters is used for cooking meals and heating water, replacing the use of coal stoves which was used in absence of the project activity.

How do biogas projects help fight global warming?

In biogas facilities, biomass is fermented into biogas in sealed digesters. Biomass may consist of organic waste or dung from cows or other animals. In countries like India or Vietnam, families use the gas from small biogas plants for cooking. This reduces CO2 emissions that would be produced by cooking with wood or charcoal. Biogas plants also prevent methane from escaping into the atmosphere, as is the case when organic waste is stored in an open pit. Instead, the gas is fed from the closed digesters to specific cookers and thus provides an independent and renewable source of energy.

The project aims to contribute to these United Nations’ Sustainable Development Goals (SDGs).

Project facts

Climate projects generally fall into one of three groups: carbon reduction, carbon removal, or carbon avoidance. Carbon reduction projects reduce the amount of greenhouse gas emissions produced by a specific activity (e.g., improved cookstoves). Carbon removal projects remove carbon from the atmosphere by sequestering it in carbon sinks (e.g., reforestation). Carbon avoidance projects avoid greenhouse gas emissions entering the atmosphere (e.g., protecting forests from deforestation with REDD+ projects).

All climate projects are based on international standards. They set processes and requirements which carbon projects must fulfill to be recognised as a proven method of reducing carbon emissions.

Climate projects demonstrably reduce, remove, or avoid greenhouse gas emissions. This is achieved with various technologies, ranging from nature-based solutions to social impact projects and renewable energies.

Most standards on the voluntary carbon market list their projects in public registries. The registries are used to store project data and track issuances and retirements of verified emission reductions. The registry ID can be used to identify projects in the standard registry.

This figure shows the estimated annual emission reductions calculated before the project started. The actual number of emissions saved in each monitoring period may differ. The background to this process is that in order to be registered as a climate project, the project operator must submit the calculation of the estimated emissions savings using the ex-ante methodology in a Project Design Document (PDD), which is similar to a business plan. This calculation is validated by an independent auditor. The values determined in the PDD are recalculated during regular monitoring periods based on actual project performance, documented in a monitoring report, and verified again by independent auditors at the end of the monitoring period to ensure a robust process. Independent verification thus provides ex-post verification of actual emission reductions. Verified emission reductions are not distributed until the savings have actually been made.
