Abstract: This study has aimed to recommend an innovative approach which is biochar adsorption process to mitigate greenhouse house gas (GHG) emissions resulted from groundwater treatment. This study has showed a point of view to present the potential of biochar application on the mitigation of GHG emissions from groundwater treatment. There is a limited point of view to minimise the GHG emissions due to water resources treatment. This study has proposed to mitigate nitrous oxide (N₂O) and carbon dioxide (CO₂) emissions originated from groundwater treatment using biochar derived from pomegranate (Punica granatum) peels, carob (Ceratonia siliqua) seeds and Turkish coffee (Coffea Turkish) residue generated by solar assisted pyrolysis. A GHG emission calculation and mitigation index (GHGIBA) based on biochar adsorption process has been developed and validated in this study. According to the Monte Carlo simulation, the recommended indicator (GHGIBA) has been meaningful in the range of 89 ± 0.11%.
