"Emissions of methane from fossil fuel extraction and refining activities in the South Central United States are nearly five times higher than previous estimates, according to researchers at Harvard University and seven other institutions [including AER]. Their study, published this week in Proceedings of the National Academy of Sciences (PNAS), also suggests that the contribution from livestock operations may be twice as high as previously thought."

AER scientists Janusz Eluszkiewicz and Thomas Nehrkorn, are co-authors of the Harvard-led study "Anthropogenic emissions of methane in the United States" which is receiving considerable attention worldwide for its conclusion that methane emissions in the U.S. are significantly greater than previous estimates.
