Permian Oil Fields Leak Enough Methane for 7 Million Homes (1)

Enough gas to supply 7 million homes is leaking into the atmosphere above oil fields in Texas and New Mexico—the largest plume of climate change-driving methane pollution ever recorded over a U.S. oil field, a new study from Harvard University and Environmental Defense Fund shows.

The methane over the Permian Basin emitted by oil companies’ gas venting and flaring is double previous estimates, and represents a leakage rate about 60% higher than the national average from oil and gas fields, according to the research, which was published Wednesday in the journal Science Advances.

“Our study found that the quantity ...
