Earthworks, a nonprofit which works to protect communities from the impacts of mineral and fossil fuel extraction and promote sustainable energy development, has released a new report showing that the flaring of natural gas waste in just two shale plays, or exploration areas, is the equivalent of an additional 1.5 million cars on the road. The flares occur when natural gas is burned rather than captured.

In June 2014, the Eagle Ford shale produced seven billion cubic feet per day, while the Bakken produced 1.3 billion cubic feet per day. Produced gas includes gas that is flared and gas that is captured for use. Above, flaring in the Bakken. Photo credit: Sarah Christianson

The report, “Up in Flames: U.S. Shale Oil Boom Comes at Expense of Wasted Natural Gas, Increased Carbon Dioxide,” accompanied by an interactive map by SkyTruth, a group that provides aerial evidence of environmental impacts. This map allows people to track flaring activity in the U.S. and around the world based on nightly infrared data collected by a National Oceanic and Atmospheric Administration (NOAA) satellite.

SkyTruth’s chief technology officer Paul Woods pointed to the potential impact of this map:

This new tool makes the scale and frequency of flaring more comprehensible and less abstract. Hopefully, enabling everyone to see where, when, and how often operators are flaring will create public pressure on government and industry to reduce the waste of this hard-won natural resource.

The report specifically looks at waste created in the North Dakota Bakken and Texas Eagle Ford development areas and how lax regulations and oversight enable this waste, a byproduct of fracking.
