reports for InsideClimate News. "The earlier paper relied on less precise, region-wide satellite data."
Lead author Christian Frankenberg, an environmental science and engineering professor at the California Institute of Technology, told McKenna, "It's good news, because with the techniques that we have developed here, it's possible to find the dominant leaks that we can target for methane emissions mitigation,"
The Four Corners region, which spans more than 1,000 square miles, "is one of the nation's largest producers of coal-bed methane and releases about 600,000 metric tons of methane into the atmosphere each year," McKenna writes. "The study is the latest to show that a small number of 'super-emitters,' mainly from oil and gas operations, are responsible for the majority of U.S. methane emissions."
