Between 2007 and 2019, across much of the United States, nitrogen dioxide pollution levels dropped because of cleaner cars and power plants, the team found, confirming findings reported previously. The clean air trend in satellite data was most obvious in urban areas of California, Washington and Oregon and in the eastern half of the continental United States… However, several areas stuck out with increased emissions of nitrogen dioxide: The Permian, Bakken and Eagle Ford oil and gas basins, in Texas and New Mexico, North Dakota, and Texas, respectively.

During two days of intensive airborne measurements, oil and gas operations in Colorado’s Front Range leaked nearly three times as much methane, a greenhouse gas, as predicted based on inventory estimates, and seven times as much benzene, a regulated air toxic. Emissions of other chemicals that contribute to summertime ozone pollution were about twice as high as estimates, according to the new paper, accepted for publication in the American Geophysical Union’s Journal of Geophysical Research: Atmospheres.

In Utah’s Uintah Basin, scientists testing a new way to measure methane emissions from a natural gas production field found leakage of 6 to 12 percent of the methane produced, on average, there on February days. A recent federal report estimated that methane’s leak rate, nationally, is less than 1 percent of production. But another report noted that emissions in the Uintah Basin may have higher emissions than typical for western gas fields. The Uintah Basin produces about 1 percent of total U.S. natural gas,

Mark Zoback, a geophysicist at Stanford University, cringes at the word “fracking”. He doesn’t oppose this controversial process of extracting fossil fuels from shale rock, or hydraulic fracturing. He just laments the stigma of its nickname.
