For the last several years, researchers have been studying methane emissions in the Permian Basin (the nation’s largest oil field) to try and understand just how much climate pollution specific oil companies may be responsible for. A new study published this week from EDF and Carbon Mapper offers insights into how we answer that question.

After three years of actively collecting methane emissions data in the Permian Basin, researchers have gained new insights that will make it easier to reduce emissions of the incredibly potent greenhouse gas methane. These insights are helping inform state and federal regulatory approaches at a critical time.

Methane emissions from natural gas gathering pipelines in the U.S. Permian Basin are at least 14 times greater than Environmental Protection Agency national inventory estimates, according to new peer-reviewed research from EDF, Stanford University and the University of Arizona. Gathering lines transport unprocessed gas from well sites to processing facilities and vary widely in size and pressure, with diameters ranging from two inches to as large as 30 inches. Methane is a potent greenhouse gas with over 84 times the warming potential of carbon dioxide over its first 20 years in the atmosphere, and this new research indicates the importance of finding and fixing pipeline methane leaks to mitigate the climate crisis.
The last two months have seen encouraging momentum in the effort to tackle emissions of methane — a greenhouse gas that drives over a quarter of current warming — and the practice of flaring, which is a major source of energy waste and methane pollution.
Starting with last month’s Major Economies Forum, one of the last major climate gatherings before COP 27 in Egypt, signatories to the Global Methane Pledge introduced a new goal to end routine flaring as soon as possible, and by 2030 at the latest.
Then, just this week, the U.S. and Mexico announced a commitment to cooperate and help Mexico develop a plan to eliminate routine flaring in alignment with the Global Methane Pledge.
Fast action to end routine flaring is critical for reducing emissions of methane, protecting human health and the climate, and stopping needless waste of energy resources as the world faces an energy crisis spurred by Russia’s invasion of Ukraine.
Now, the U.S. has work to do to ensure domestic policies can live up to our own global commitments. Fortunately, both the Bureau of Land Management and the Environmental Protection Agency have the authority and obligation to implement strong rules that end routine flaring.

Newly released research is shedding more light on the largest sources of methane emissions in the nation’s largest oilfield.
Methane is an extremely potent greenhouse gas and has a huge impact on the current rate of global warming. The oil and gas industry is one of the biggest emitters.
Using a helicopter equipped with an infrared camera, we surveyed over a thousand sites across the Permian Basin to get specific information about the types of facilities, equipment and events that make the Permian Basin the highest-polluting oilfield in the country. Three things immediately stood out.

Even amidst a global pandemic and market volatility that reduced oil and gas activity, at least one thing didn’t change in the Permian last year: operators can’t seem to keep their flares lit.
Throughout 2020, EDF conducted aerial surveys of portions of the Permian Basin to determine the performance of natural gas flares. Even when done properly, flaring is a wasteful, polluting practice that has earned industry “a black eye.” But when flares malfunction they also become major sources of highly potent, climate-polluting methane.
Over the course of 2020, we conducted periodic surveys of flares in various parts of the Permian. These took place in February, March, June and November, and included a series of consecutive, repeat surveys of one specific area on November 2, 4 and 6 meant to understand how long flare malfunctions persist. In total, we studied nearly 1,200 flares in the region.
