Fracking gas leaks less than previous estimates, US study finds
Natural gas leaks from production wells are lower than previous estimates and below the level that would erase the fuel’s climate benefit over coal, according to a University of Texas study backed by both industry and environmentalists.
The study being released on Monday, the first to use actual measurements of emissions, found that 0.42 per cent of natural gas produced in the US is released into the atmosphere. A 2010 Cornell University study using data provided by drillers estimated leakage at 0.6 to 3.2 per cent.
“The industry has led efforts to reduce emissions of methane by developing new technologies and equipment, and these efforts are paying off,” Howard Feldman, director of regulatory and scientific affairs for the American Petroleum Institute, said in a statement. “Capturing methane is helping operators deliver more natural gas to consumers, creating a built-in incentive to continue reducing these emissions.”
The companies were not involved in processing data captured at the well sites. The study was peer reviewed and accepted for publication in the Proceedings of National Academy of Sciences, a scientific journal.
