But the rule falls short, in part because EPA has systematically underestimated methane emissions from the oil and gas industry. Emissions from conventional natural gas are likely to be at least 2- to 3-fold greater than the EPA estimates, according to several recent studies. Recent literature also suggests emissions from shale gas may be twice as much greater still, based on an observed large increase in methane in the atmosphere over recent years, with the… [more]
