Abstract
The paper presents the estimate of externalities caused by methane emission from exploitation of the municipal solid waste landfill in the years 2002-2009. Methane emission was calculated according to the methodology recommended by the IPCC which is briefly presented in the paper. The following parameters were evaluated: mass of the landfilled wastes, correction coefficient for methane based on the landfill characteristics, content of biodegradable carbon based on waste morphology and mass of recovered methane. Based on these parameters, the amount of methane emitted from the landfill during 2002-2009 was estimated at 3.16 Gg.
