About the methodologyFossil fuels like natural gas, oil, and coal drive 75% of global greenhouse gas (GHG) emissions. While low-emission alternatives exist, various barriers slow their adoption. Biogas, produced through the anaerobic digestion of organic materials such as agricultural waste, offers a renewable solution. It can be used for gas network injection, cogeneration, or heat generation, with the added benefit of producing digestate—a nutrient-rich fertilizer for agriculture.The Riverse methodology supports projects that transform organic waste into renewable biogas.Read documentationTechnologyAnaerobic digestion is a biological process where microorganisms break down organic matter in the absence of oxygen, producing biogas (a mixture of methane and carbon dioxide) and digestate.The biogas can be used to generate electricity, heat, or be upgraded to biomethane for injection into the gas grid or as vehicle fuel.Scientific approachThe methodology quantifies GHG emissions avoided using the ISO 14064-2 standard. The baseline considers the market mix of gas consumed in the country where the project operates, as biomethane is injected into the national grid.The project scope includes feedstock provisioning and transport, digestion and biomethane management, digestate storage and spreading.Our calculations compare the emissions from the baseline scenario to those of the project scenario.Compliance)
