Abstract: This study evaluates the efflux of carbon dioxide (CO₂) and methane (CH₄) gases by the application of static flux chamber (SFC) method at Balicha landfill site (BLS) and Titardi landfill site (TLS) situated in semiarid region of Rajasthan for a period of 2018 and 2019. The geometric mean flux of CO₂ and CH₄ fluxes at BLS during the studied period ranged from 0.522 to 0.787 gm/m²/day and 0.175 to 0.252 gm/m²/day, respectively. Whereas the geometric mean fluxes of CO₂ and CH₄ at TLS straddled from 0.272 to 0.472 gm/m²/day and 0.087 to 0.134 gm/m²/day sequentially in the same given period. The carbon footprint generated from the BLS and TLS was approximately 0.156 Gg/yr and 0.0135 of CO₂ equivalent. The results, statistically quantified using the coefficient of variation, demonstrated that the considerable temporal fluctuation in the CO₂ and CH₄ gas emanation fluxes at BLS and TLS was noticed so mitigation is needed.
