An environmental group says that Pennsylvania’s gas drilling industry is releasing much more methane into the atmosphere than the state is reporting.
Scientists at the Environmental Defense Fund calculated Pennsylvania’s Marcellus shale industry is emitting twice as much methane as companies are reporting to the state’s Department of Environmental Protection. The analysis, posted to the group’s website, is based on 16 peer-reviewed studies funded in part by EDF, including some involving oil and gas companies.
