Decomposing waste in these landfills produces landfill gas, which is a mixture of about half methane and half carbon dioxide. Landfills are the third-largest source of methane emissions in the United States, with municipal solid waste landfills representing 95 percent of this fraction. [18] [19]
Roughly 120 kg of methane is generated from every ton of MSW. Methane has a global warming potential of 25 [2] times more effective of a greenhouse gas than carbon dioxide on a 100-year time horizon. It is estimated that more than 10% of all global anthropogenic methane emissions are from landfills. [21]

The gas that is produced by landfills is about half methane and half carbon dioxide and water vapor, in addition to a small amount of other organic compounds. Pumpkins sit in a field in Colorado ...
Landfills are the third-largest source of methane emissions in the United States, with municipal solid waste landfills representing 95 percent of this fraction. [15] [16] In the U.S., the number of landfill gas projects increased from 399 in 2005, to 594 in 2012 [17] according to the Environmental Protection Agency.
The Landfill Methane Outreach Program (LMOP) promotes the use of landfill gas, a naturally occurring byproduct of decaying landfill waste, as a sustainable energy source. [74] Besides reducing emissions, landfill gas utilization has also been credited for reductions in air pollution, improvements to health and safety conditions, and economic ...
