> The report doesn’t identify these “super emitters,” but notes that landfills give off more methane than any other source in the state. NASA’s equipment found that a subset of these landfills were the largest emitters in California and exhibited “persistent anomalous activity.”

Is the problem here that the trash is breaking down, or it's breaking down in a suboptimal way (such as anaerobic activity) that's causing methane to be released instead of a more benign gas?
