Description AgSTAR is an outreach program designed to reduce methane emissions from livestock waste management operations by promoting the use of biogas recovery systems. Biogas recovery systems are anaerobic digesters that capture and combust biogas to produce electricity, heat or hot water. AgSTAR provides information and tools to assist producers in the evaluation and implementation of these systems. AgSTAR is a collaborative effort of EPA, the U.S. Department of Agriculture, and the U.S. Department of Energy. Collaborates with the Global Methane Initiative (GMI) - a partnership that aims to reduce global methane emissions and advance the abatement, recovery and use of methane as a valuable clean energy source.

Commitment:In June 2015, in partnership with the dairy industry, the USDA, EPA and DOE will jointly release a “Biogas Roadmap” outlining voluntary strategies to accelerate adoption of methane digesters and other cost-effective technologies to reduce U.S. dairy sector greenhouse gas emissions by 25 percent by 2020. Achieved emission reductions to date: The initiative claims ( that anaerobic digestion systems have accomplished the avoidance of 2,5 million metric tons of CO2 equivalent in 2013. It does not say how much of this depends on AgSTAR activities. The larger part of the emission avoidance is due to capture of methane that would otherwise have leaked into the atmosphere. The rest is due to use of renewable energy instead of fossil fuels

Activities AgSTAR provides outreach materials and project development tools, funding resources, events, information on operating digesters, pre-feasibility analyses, newsletters and listservs, and access to experts. AgSTAR also maintains a database of anaerobic digesters operating at commercial livestock farms in the US.

AgSTAR collaborates with the Global Methane Initiative (GMI) to promote biogas recovery technologies outside the United States. The GMI’s Agriculture Subcommittee facilitates biogas recovery system development in the agricultural sector in countries around the world.
