Estimation of methane emission from the landfills is very much required for fast urbanizing countries. Rapid growth in population and industrialization causes a direct impact on the environment. As methane emission is a key contributor to the greenhouse effects it is necessary to quantify the methane emission from municipal solid waste (MSW), so as to take measures to ease the greenhouse gas emission. In this present study four models have been used to quantify the LFG emission estimation characteristics from MSW in six metropolitan cities covering different parts in India for a period of 30 years (1982 - 2012).
