Methane in the Inventory of the U.S. Greenhouse
Gas Emissions and Sinks

About Our Speaker

Melissa Weitz is an environmental protection specialist in the Climate Change Division of EPA’s Office of Air and Radiation.  She joined EPA in 2005 and has focused on greenhouse gas emissions quantification methods, for a variety of emissions sources and a number of different programs. Her current work focuses on emissions estimates for oil and natural gas systems.  She received a BS degree in Animal Science and a Master of Energy and Environmental Policy from University of Delaware.

About the Talk

EPA leads the development of the Inventory of U.S. Greenhouse Gas Emissions and Sinks (GHG Inventory), a national assessment of total GHG emissions from man-made sources in the U.S. The report contains national estimates of methane emissions, with the largest emissions coming from livestock, oil and natural gas, and the waste sector. This talk will describe the methane data available, and methods used to develop these estimates for the GHG Inventory.  It will also discuss challenges and considerations for comparing the GHG Inventory estimates to results from top-down studies.
