There's new evidence, collected from orbiting satellites, that oil and gas companies are routinely venting huge amounts of methane into the air.
Methane is the main ingredient in natural gas, the fuel. It's also a powerful greenhouse gas, second only to carbon dioxide in its warming impact. And Thomas Lauvaux, a researcher with the Laboratory of Climate and Environmental Sciences in France, says there's been a persistent discrepancy between official estimates of methane emissions and field observations.
"For years, every time we had data [on methane emissions] — we were flying over an area, we were driving around — we always found more emissions than we were supposed to see," he says.
Researchers turned to satellites in an effort to get more clarity. The European Space Agency launched an instrument three years ago called the TROPOspheric Monitoring Instrument (TROPOMI) that can measure the methane in any 12-square-mile block of the atmosphere, day by day.
Lauvaux says that TROPOMI detected methane releases that the official estimates did not foresee. "No one expects that pipelines are sometimes wide open, pouring gas into the atmosphere," he says.
