Global satellite survey reveals uncertainty in landfill methane emissions.

ABSTRACT: Methane is a potent but short-lived greenhouse gas and rapid reductions of its anthropogenic emissions could help decrease near-term warming¹. Solid waste emits methane through the decay of organic material, which amounts to about 10% of total anthropogenic methane emissions². Satellite instruments³ enable monitoring of strong methane hotspots⁴, including many strongly emitting urban areas that include solid waste disposal sites as most prominent sources⁵. Here we present a survey of methane emissions from 151 individual waste disposal sites across six continents using high-resolution satellite observations that can detect localized methane emissions above 100 kg h^-1. Within this dataset, we find that our satellite-based est
