This study has been undertaken to investigate the emission of Greenhouse Gases (GHG) mainly constituting Carbon dioxide (CO2), Methane (CH4) and Nitrous oxide (N2O) from water & Wastewater treatment plants Particularly Sewage treatment plants which are considered as sources of GHGs (greenhouse gases) production mainly methane, carbon dioxide, and nitrous oxide which are produced during the biological sewage treatment process, and offsite electricity production which is a major source of carbon dioxide generation using the Steps and guidelines suggested in IPCC 2006[1] as well as RTI USEPA[2]. To analyze the carbon footprint of the treatment plants. The Study include energy utility consumption, Wastewater parameters before and after its treatment and sludge. The study is one in 3 different treatment plants in Ahmedabad. For the monthly time series data has been arranged from Jan 2020 to Dec 2020. The analytical framework contains Scope 1 and Scope 2 emissions As per WRI GHG Protocols.
