Methane, a powerful greenhouse gas, is leaking from industry sites at rates equivalent to the annual carbon emissions of France and Germany combined, a new analysis using satellite data shows.

These events alone emitted around 20 million tonnes of methane—the short-term equivalent to releasing 1.8 billion tonnes of carbon pollution.

"The good news is most of these are man-made and can easily be addressed through action by individual companies, governments and regulators," said Antoine Rostand, CEO of Kayrros, an asset observation platform that conducted the analysis.
