• Advisors to the Nation on science, engineering, and medicine.
• The National Academies is the umbrella term for NAS, NAE, NAM, and NRC.
• NAS created in 1863 under Lincoln Administration.
Strengths of our work:– Stature of Academies’ memberships
– Ability to get the very best to serve
– “Pro bono” nature of committee service
– Special relationship to the government
– Quality control procedures
– Independence, scientific objectivity, balance
The National Academies
• Rationale – Numerous new analyses of methane emissions– Need for review and assessment of numerous results in
this area, examination of state of the science, and identification of remaining gaps
• Sponsors– DOE– EPA– NASA– NOAA Marchese et al. 2015 ES&T
Study Motivation
EPA GHG Inventory

Statement of Task• Examine approaches to measuring, monitoring,
presenting, and developing inventories of anthropogenic emissions of methane to the atmosphere
• Covers predominant sources of anthropogenic methane emissions
• Specifically for U.S.– although report could be relevant internationally
Committee Members• James W.C. White, Chair, University of Colorado Boulder• David Allen, The University of Texas at Austin• Praveen K. Amar, Independent Consultant • Jean Bogner, University of Illinois, Chicago• Lori Bruhwiler, National Oceanic and Atmospheric Administration
Earth Systems Research Laboratory (NOAA/ESRL)• Daniel Cooley, Colorado State University• Christian Frankenberg, Jet Propulsion Laboratory • Fiji George, Southwestern Energy• Lisa Hanle, Independent Consultant• Alexander Hristov, Pennsylvania State University• Ermias Kebreab, University of California, Davis• April Leytem, USDA-Agricultural Research Service• Maria Mastalerz, Indiana University• Steven Wofsy, Harvard University
Staff:• Katie Thomas• April Melvin• Michael Hudson
• Helps ensure the committee is informed on relevant aspects of topic
• Allows for engagement with broader scientific community and other stakeholders
• Today’s workshop is one of multiple information gathering sessions planned for coming months
Information gathering is an important step in the study process
A.Melvin
• Provide the committee with insights on some important topics related to charge, including:
– Methodologies for measuring methane emissions in various sectors
– Methane-related activities in California– Strategies for presenting study results to meet user
needs
Goals for today’s meeting
L. Bruhwiler, NOAA, F. George, J.Bogner
• Session 1: Methane measurement methodologies and taxonomy
• Session 2: California methane activities: stakeholder engagement, regulations, and state-level decision making
• Session 3: Measuring methane emissions from the agricultural sector
