Agricultural biodigesters reduce greenhouse gas (GHG) emissions & generate clean energy. GHG reduction depends on many factors
(design, feedstock, etc.), including the amount of fugitive CH4 emissions. Quantifying fugitive emissions is difficult -- commonly
- 15% of total CH4 production (California Climate Action Registry )
- 15% of production (CDM 2005); 10% of production (IPCC 2006)
- 5% of production (EPA – for covered anaerobic lagoons)
