14x More Methane Leaking From
Gathering Lines Than U.S. EPA Estimates

Enough methane gas leaks from pipelines
between Permian wellheads and processing facilities to power 2.1
million homes, a study published Tuesday in
Environmental Science and Technology Letters finds. The
213,000 metric tons of methane escaping from so-called gathering lines
is 14 times higher than a previous EPA finding. The study represents
the second finding that EPA is
underestimating methane pollution in as many weeks and is at least
the
fourth such finding this year.
Methane, the main ingredient in so-called
“natural gas,” is an extremely potent greenhouse gas, trapping more
than 80 times more heat in the atmosphere than CO2 over a 20-year
period. The assessment, conducted by researchers from Stanford, U. of
Arizona, EDF, and Carbon Mapper, is based on aerial surveys and did
not examine the mechanisms by which methane was escaping from
gathering lines. Methane pollution, especially from
oil and gas operations owned by private equity firms in the
Permian Basin, is
increasing — as is its
prominence in global efforts to address the climate crisis.
