Methane Emission Estimates Are Lower Than They Should Be
A study from Carnegie Mellon University and Harvard says that previous estimates underestimate the true value of U.S. methane emissions—and not by a little! These researchers put values at double recent EPA estimates. The study looked at atmospheric methane observations from 2007 and 2008 to improve estimates of methane emissions from human sources like agriculture and fossil fuel drilling and refining. They found discrepancies with government estimates in several regions but particularly in the south-central US where they found emissions to be 2.7 times greater than the EPA reported. They hope this new information with help inspire more greenhouse gas reductions strategies.
