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.

Introducing WasteMAP: A New Tool to Track and Reduce Waste Methane Emissions

29 February 2024, Virtual

Until recently, methane emissions from landfills and waste have flown under the radar, and their contribution to the climate threat has largely eluded public awareness. As methane emissions have become more visible with advanced satellite and airborne remote sensing technologies, the waste sector’s ability to address methane emissions has been hindered by a lack of accessible data, actionable best practices, and evidence-based reduction measures. The Rocky Mountain Institute (RMI) and Clean Air Task Force’s Waste Methane Assessment Platform (WasteMAP) addresses these shortfalls by providing an open-source platform that brings together measured, modeled, and observed emissions data with decision support tools and recommendations for policymakers, landfill operators and other stakeholders to develop effective strategies for managing emissions from the solid waste sector.

The webinar will take place on 29 February at 10 a.m. EST (UTC -5) to learn more about the new platform, see a live demo of the tool, and find out how RMI and CATF are supporting decision makers on the ground through country engagement.

The webinar features opening remarks by Carolina Urmeneta, Waste and Circular Economy Program Director for the Global Methane Hub, who will discuss the importance of reducing methane emissions from the waste sector.

GMI Webinar: GHG Emissions from the Domestic Wastewater Sector in India

4 March 2024, Virtual

Why is mitigating methane important and what does it have to do with wastewater? Come learn about municipal wastewater and methane emissions in India. We will explore the nexus of water, energy, and methane emissions.  

India, a nation with a population that has surged from around 683 million in 1981 to over 1.3 billion in 2021, faces an immense challenge in managing its wastewater. The daily generation of sewage is about 72,368 million liters (MLD). While the total sewage treatment capacity is 31,841 MLD spread across 1,469 sewage treatment plants (STPs), the operational capacity is only 26,869 MLD and over 1,093 STPs, indicating a significant gap. Wastewater treatment facilities represent a significant source of anthropogenic greenhouse gas (GHG) emissions. Tetra Tech and TERI (The Energy and Resources Institute, India) conducted a study in support of the Global Methane Initiative (GMI) focusing on greenhouse gas (GHG) emissions from the municipal wastewater sector in India. The study analyzed secondary sources of information and compiled a comprehensive report providing national estimates of GHG emissions, specifically methane emissions. 

The webinar aims to:
  • Discuss the discrepancies in GHG accounting (focused on methane emissions) information presented by different sources to foster a deeper understanding. 
  • Share international experiences in GHG emissions inventory domestic wastewater sector.  
  • Objective is to collaboratively explore potential solutions and actions for more accurate assessments of methane emission accounting from the wastewater sector in India.
Come join us! 

Date and time: Monday, 4 March 2024 at 10:30 pm EST / Tuesday, 5 March 2024 at 9:00 am IST (UTC +5:30 hours)

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.
