Study: More Methane Leaking at PA Oil & Gas Sites than Reported

Leaks of methane, a powerful greenhouse gas, from oil and gas sites in Pennsylvania could be five times greater than industry reports to state regulators, according to a new analysis by the Environmental Defense Fund.Drawing from¬†peer-reviewed¬†research based on measurements collected downwind of oil and gas sites, along with government data, the EDF analysis estimates that the state’s oil and gas wells and infrastructure leak more than 520,000 tons of methane annually, largely due to faulty equipment.
