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. Bangladesh has been a hotspot this year for emissions of methane, a colorless, odorless gas that’s about 84 times more potent than carbon dioxide in the first two decades in the atmosphere. Scientists and government officials are seeking the fastest and most cost-effective ways to curb heat-trapping gases. “We have for the first time been able to attribute emissions in Bangladesh to a specific source,” Germain said. “This is a large source but is still not sufficient to explain the large, sustained and diffuse emissions detected over the city. The situation remains a mystery and we will continue to monitor the area.”
