A landfill in Bangladesh is leaking huge quantities of the potent greenhouse gas methane into the atmosphere, according to the emissions-tracking company GHGSat Inc.

An April 17 observation from the company’s Hugo satellite shows a methane release originating from the Matuail Sanitary Landfill, said GHGSat President Stephane Germain. The company estimated the emissions rate at about 4,000 kilograms an hour, the planet-warming equivalent of running 190,000 traditional cars. The country’s environment ministry said it’s investigating.
