Methane emissions from solid waste may represent a substantial fraction of the global anthropogenic budget, but few comprehensive studies exist to assess inventory assumptions. We quantified at hundreds large landfills across 18 states in United States between 2016 and 2022 using airborne imaging spectrometers. Spanning 20% open landfills, this represents most systematic measurement-based study methane point sources sector. detected significant source majority (52%) these sites, many with...
Airborne remote sensing observations were collected at 217 landfills across 17 states in the US 2023. We used these to attribute emissions major sources, including landfill work face, where new waste is placed and gas-control infrastructure. Methane from face appeared be more prevalent than infrastructure emissions, with 52 exhibiting out of 115 observed shown emitting Landfills often highest emitters, especially sites associated renewable natural gas facilities, total average site accounted...
