Shale Gas: Not Clean, Either?

Not only are there serious questions about just how abundant natural gas from shale plays is, it now turns out that this “Cheap, Clean, Abundant, and Domestic” resource may turn out to only be domestic.

In a draft paper, Cornell researcher Robert Howarth calculates that, when methane leakage from hydraulic fracturing is included, along with secondary contributions from forest clearance and water transport are included, the carbon footprint of shale gas is slightly worse than coal’s.
