Michael Levi, an energy expert blogging at the Council on Foreign Relations, takes another look at a study showing high levels of methane gas are leaking at shale fracking sites.
Levi says in part: "In a new paper in press at the Journal of Geophysical Research (preprint here), the same journal that published the NOAA results, I explain why the NOAA estimates are unsupportable. (Short version: great data; wrong interpretation.) I then exploit some data that the NOAA team reported but did not use in their calculations to re-estimate methane leakage rates. I find methane leakage rates that are most likely between 1 and 2 percent, very similar to what previous careful estimates have consistently indicated, but far lower than the rates — as high as 7.7 percent — that the NOAA study claimed."
