The direct or indirect emissions of carbon dioxide (CO₂), Methane (CH₄) and other Green House Gases (GHGs) expressed in terms of carbon dioxide equivalents indicate the Carbon footprint (CF) of the region, which constitutes a vital environmental indicator to mitigate global warming and consequent changes in the climate.  This study indicated that the theoretical estimation of emission from solid waste is much higher than the experimentally determined value. Total emission from ward wise waste of the city is 19.13 kg/day and 242.83 kg/day of methane and carbon dioxide, respectively. Reduction of waste generation is possible through reduced waste generation, segregation at source level, reuse and recovery of waste. Composting and anaerobic digestion are treatment options for organic waste (which constitute 70-75% of the total), whereas recycling is used for inorganic materials (15 to 18%). Wastes which cannot be treated or recycled is ultimately disposed-off at disposal site or landfill. Segregation at source  with treatment at local levels (ward levels) plays a prominent role in minimizing organic fractions getting into disposal site.

GHG emission factors vary with methodology. Experiments conducted reveal an emission of 0.013 gm of CH₄/kg of organic fraction of municipal solid waste and 0.165 gm CO₂/kg, which is much lower compared to   IPCC method (0.036 kg CH₄/kg of waste) or theoretical approaches (0.355 kg CH₄/kg, 0.991 kg CO₂/kg of waste). The current work  provides emission factor at local level which would help in  the accurate quantifications of emissions. Nevertheless comparative analysis of commonly used methods (such as IPCC) with the experimental value highlights the over estimation of GHG from waste sector with the techniques adopted earlier.
