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.
