Natural gas is mostly methane, which is a much more potent greenhouse gas, especially in the short term, with 105 times more warming impact pound for pound than CO2, said Cornell ecologist Robert Howarth. He added that “even small leaks make a big difference” and estimated that as much as 8% of the methane in shale gas leaks into the air during the lifetime of a hydraulically fractured shale gas well, which is up to twice what escapes from conventional gas production.
