Uncertainty analysis for estimation of landfill emissions and data sensitivity for the input variation

Abstract

Results of research and practical experience confirm that stabilization of GHG concentrations will require a tremendous effort. One of the sectors identified as a significant source of methane (CH4) emissions are solid waste disposal sites (SWDS). Landfills are the key source of CH4 emissions in the emissions inventory of Slovakia, and the actual emission factors are estimated with a high uncertainty level. The calculation of emission uncertainty of the landfills using the more sophisticated Tier 2 Monte Carlo method is evaluated in this article. The software package that works with the probabilistic distributions and their combination was developed with this purpose in mind. The results, sensitivity analysis, and computational methodology of the CH4 emissions from SWDS are presented in this paper.
