CelloMomOnCars, "At more than half of the hundreds of garbage dumps surveyed — in the largest assessment yet of such emissions — most of the pollution flowed from leaks, creating concentrated plumes. The researchers found these super-emitting points can persist for months or even years, and account for almost 90 percent of all measured #methane from the #landfills. Tackling these hotspots could be a huge stride toward lowering emission rates"
