Governments around the world, especially in the U.S., are also notorious for underestimating how much methane escapes into the air, said Cornell University ecology and biology professor Robert Howarth, who studies natural gas emissions. “Everybody claims they have reduced their emissions, but it’s not true,” Lauvaux said.

In the Permian Basin, the largest oil and gas field in the United States, methane emissions were two to three times higher than what companies reported, he said. Scientists measuring methane from satellites in space have found that methane emissions from oil and gas operations are usually at least twice what companies reported, said Thomas Lauvaux, a scientist at University of Reims in France. It escapes into the atmosphere from well sites and across the natural gas distribution network, from pipelines and compressor stations, to the export terminals that liquefy gas to ship it overseas. That matters because natural gas, a fossil fuel widely used to heat homes and provide electricity, is made up of methane, a potent climate warming gas. It is believed to be the single biggest recorded gas leak over a short period of time.īut as serious as the methane escaping from ruptured pipelines may be, there are alarming incidents of massive methane releases around the world frequently.Ĭlimate scientists have found that methane emissions from the oil and gas industry are far worse than what companies are reporting, despite claims by some major firms that they’ve reduced their emissions. NEW YORK (AP) - Scientists have been measuring the scale of the massive methane leak from damaged pipelines in the Baltic Sea, with the latest figures equating the levels of gas escaping to the annual emissions of some whole countries.
