Methane is one of the main greenhouse gases (GHGs) that contributes considerably to global warming, thus being a major source of concern. GHGs entering the atmosphere are the primary cause of climate change globally, which is manifested in violent storms, increasing sea levels, and deluges. Waste dumping is considered one of the main sources of these gases due to the increased waste accumulation in landfills. As a result, landfill gas generation continues to be released into the atmosphere which contains mainly methane and carbon dioxide. The potential of dust emission into the atmosphere is also significant because of different waste management activities. This review attempts to outline landfill emissions quantification methods and factors, as well as their potential control options by primarily focusing on methane and dust emissions.
