This week the National Academy of Sciences, Engineering and Medicine (NAS), the nation’s most prestigious scientific organization, issued a report calling for a stepped-up nationwide research effort to develop a gridded and verifiable inventory of U.S. methane emissions.
The NAS report, sponsored by the U.S. EPA, Department of Energy (DOE), National Oceanic and Atmospheric Administration (NOAA), and NASA, noted atmospheric methane has risen dramatically in the 20th century, hitting a spike in 2016 that has tripled since pre-industrial times. Methane is a potent greenhouse gas responsible for about 25% of current global warming.
The report discusses all the major U.S. sources of anthropogenic methane emissions, including petroleum and natural gas systems, agriculture, landfills, and coal mines. Researchers acknowledged the rapid increase in natural gas production in the U.S. during the past decade has triggered the need for a better understanding of the energy industry’s methane footprint. The NAS report classified oil and gas as one of three primary research priorities for the future, along rice farming, and livestock.
