Tell us how you’re reducing methane emissions

Biogas Sector

The GMI Biogas Subcommittee focuses on building capacity within Partner Countries to leverage common interests across the areas of agriculture, municipal solid waste, and municipal wastewater. These interests include biogas energy use, the types of wastes managed, waste treatment technologies, and the potential for synergistic projects involving input streams from multiple sources. Efforts include developing and promoting tools, policy guidance, and project development resources at the national, state, and city level within Partner Countries.

GMI Technical Groups

Within the Biogas Sector, GMI maintains active technical groups in the areas of agriculture, municipal solid waste (MSW), and municipal wastewater. These groups provide international leadership to mitigate global methane emissions through the abatement, recovery, and use of methane. They promote collaboration between delegates from Partner Countries and Project Network members to build capacity, develop strategies, and expand opportunities for using methane as a renewable energy resource.


Methane emissions come from livestock enteric fermentation, livestock waste management, rice cultivation, and agricultural waste burning.

Municipal Solid Waste

Municipal solid waste management and treatment activities such as landfilling and anaerobic digestion are sources of methane emissions worldwide.

Municipal Wastewater

Methane is produced when the organic material in municipal wastewater decomposes anaerobically.

Biogas Toolkit (U.S. EPA) (2020)

The U.S. Environmental Protection Agency (EPA) Biogas Toolkit serves as a centralized knowledge hub for biogas project stakeholders. The toolkit is designed to allow stakeholders to search and browse for information and resources that meet their specific project needs. The toolkit includes information and resources compiled from across several EPA programs, including AgSTAR, the Landfill Methane Outreach Program (LMOP), and GMI.

Solid Waste Emissions Estimation Tool (SWEET) (2020)

SWEET is a free Excel tool created by the Waste Initiative. SWEET helps users scope emissions sources such as waste collection and transportation, open burning, landfill gas collection systems, organic waste management projects, waste handling equipment (e.g., bulldozers), and waste incineration facilities. It estimates waste sector emissions including methane, black carbon, and several other pollutants. It also evaluates emissions reduction benefits of multiple alternative waste management scenarios.

OrganEcs (2016)

OrganEcs aims to help local decision makers in their first evaluation of different treatment options (e.g., composting options and/or anaerobic digestion options). OrganEcs helps users determine the economic feasibility of waste management scenarios by calculating tipping fees, sales of products (e.g., organic compost), and the internal rate of return. OrganEcs use requires expert support.

Biogas Wastewater Assessment Technology Tool (BioWATT) (2016)

The Biogas Wastewater Assessment Technology Tool (BioWATT) provides a quick and preliminary assessment of wastewater-to-energy projects. Through BioWATT, users can receive a specific summary of their biogas production estimates for various wastewater-to-energy technologies, electricity generation potential from the produced biogas, greenhouse gas savings associated with biogas-generated electricity, and more.

International Best Practices Guide for Landfill Gas Energy Projects (2012)

Global Methane Initiative’s (GMI) International Best Practices Guide for Landfill Gas Energy Projects provides a broad overview of the development process for LFGE projects in international settings and presents the technological, economic and political considerations that typically affect the success of LFGE projects. The goal of the guide is to encourage environmentally and economically sound LFGE projects by connecting stakeholders with available information, tools and services. The guide is not intended to provide a step-by-step protocol for project development.

Central and Eastern Europe Landfill Gas Model

The Model can be used to estimate landfill gas generation rates from SWD sites, and potential landfill gas recovery rates for disposal sites that have, or plan to have, gas collection and control systems and are located in Central or Eastern European countries. The Model also may be used for SWD sites in other countries which experience similar site conditions and climate, and have waste composition data.

Scaling Sludge Mountains: Breaking Down Barriers for Chinese Cities to Turn Sludge Waste into Energy (2019)

The Wilson Center’s China Environment Forum (CEF) produced this sludge scoping report for the U.S. EPA and the Global Methane Initiative. The report describes drivers that created mountains of municipal sludge, introduces key political and research entities involved in sludge regulation in China, reviews obstacles in adoption of anaerobic digestion, provides a case study of the challenges facing sludge-to-energy projects, and highlights opportunities for U.S. government, cities, and companies to engage with Chinese government agencies.

Naucalpan, Mexico Waste Characterization Study (2019)

In March 2017, the U.S. Environmental Protection Agency – as a lead partner in the Waste Initiative – conducted a waste characterization study at the municipality’s transfer station. The study indicated that approximately 69% of the waste handled at the transfer station could be recycled or otherwise diverted from the landfill, and that more than half of the waste could be used as feedstock in composting or anaerobic digestion projects. The municipality is using the results of the study to inform decision making about the project design and procurement options.

From Farm to Table to Energy: Co-digesting China’s Urban Food Waste in Wastewater Treatment Plants (2019)

Prepared by the Wilson’s Center China Environment Forum with assistance provided by GMI, the report highlights food waste trends in Chinese cities and assesses the possibilities of redirecting food waste to municipal wastewater (MWW) and sludge-to-energy (StE) plants. This report also highlights some specific gaps that GMI and other organizations could help fill and potential Chinese partners to engage with to highlight the environmental and economic benefits of co-digestion.

Biogas Done Right - Introduction (2019)

Jorge Hilbert explains and introduces the importance of biogas in the agricultural sector, while additionally explaining biogas’s potential for increasing future energy efficiency and technological sustainability.

Using Animal Manure as a Resource (2019)

Anaerobic digestion, or AD, is the biological process that breaks down biological materials like compost or manure into biogas. Livestock manure accounts for 3 percent of man-made methane emissions globally. Methane, when captured and stored, can be used to generate electricity and heat, or it can be processed into natural gas fuel. By capturing the biogas, we are also preventing the release of methane, one of the most potent greenhouse gases, to the atmosphere.

Methane Mitigation Matters: Climate Change (2015)

Methane is a prevalent manmade greenhouse gas that traps 28 times more heat than carbon dioxide (CO2). Reducing methane emissions by recovering and using methane as a clean energy source offers many benefits for the environment and local communities. This video highlights the many ways that reducing methane can benefit the environment and local communities.
