USDA- EPA – DOE, December 2015: “This report is a progress report of the Biogas Opportunities Roadmap originally published in August 2014. The U.S. Department of Agriculture (USDA), U.S. Department of Energy (DOE), and U.S. Environmental Protection Agency (EPA) created the Roadmap as a response to the White House Climate Action Plan’s directive to develop an interagency strategy to reduce methane emissions. Strategically deployed biogas systems offer the nation a cost-effective and profitable solution to reducing emissions, diverting waste streams, and producing renewable energy.”
