One of the central tenets of anti-shale gas activists—claims that carbon pollution from methane leaked during the hydraulic fracturing extraction process makes natural gas more polluting than coal—took another, likely fatal, hit this week.
A University of Texas-Austin study released Monday found that methane emissions from new wells being prepared for production, a process known as completion, captured 99% of the escaping methane—on average 97% lower than estimates released in 2011 by the Environmental Protection Agency. It is the most comprehensive shale gas emissions study ever undertaken on methane leakage, covering 190 well pads around the United States. Methane is a potent greenhouse gas, so leaks could theoretically wipe out the documented climate benefits with respect to reduced carbon emissions of natural gas, a comparatively clean fossil fuel.
