(Image credit: ESA/GHGSat) Huge amounts of uncounted emissions of highly warming greenhouse gas methane are being released by “super-emitters” all over the world, satellite observations reveal.
Scientists have only recently worked out how to detect methane emissions from space, but what they have seen since has taken them by surprise. The greenhouse gas, which is 80 times more potent than carbon dioxide, is leaking from gas pipelines, oil wells, fossil fuel processing plants and landfills all over the world. It is frequently released through negligence and improper operations; the emissions, in many cases, are not accounted for in mandatory greenhouse gas inventories.
“We see quite a lot of those super-emitters,” Ilse Aben, senior scientist at the Netherlands Institute for Space Research (SRON) told Space.com. “These are large emissions, and we see a lot of them on the global scale — much more than we had expected.”
