Emissions due to solid waste disposal on land

Year: 2005
From collection: Vital Waste Graphics
Author: Philippe Rekacewicz, UNEP/GRID-Arendal
Landfi ling is the most common waste management practice, and results in the release of methane from the anaerobic decomposition of organic materials. Methane is around 20 times more potent as a GHG than carbon dioxide. If the disposal of organic matter were to be decreased (for example by composting or incineration) it would be possible to reduce the amount of methane emissions. However, landfill methane is also a source of energy, and some landfills capture and use it for energy. In addition, many materials in landfills do not decompose fully, and the carbon that remains is sequestered in the landfill and not released into the atmosphere.
