The use of diesel generator (DG) sets for power backup at various places like malls, shopping centres, wedding gardens, offices buildings etc. increases the air pollution levels in the cities and causes severe health and environmental problems. A study of emission inventory for the air pollutants released from the diesel generators used at malls, shopping centres and wedding gardens in Jaipur city, India has been carried out to estimate concentration of air pollutants viz: oxides of nitrogen (NOx), oxides of sulphur (SOx), particulate matter (PM10), hydrocarbon (HC) and carbon monoxide (CO) by using questionnaire survey of the users comprising of managers and DG operators. 16 wedding gardens, 6 malls and 2 shopping centres located within the city were identified for calculation of data for the period between May 2018 to July 2018. It has been observed that in the wedding gardens 62, 125 and 250 KVAs of DG sets are used, whereas, malls and shopping centres used 8 types DG sets ranges from 62 to 1650 KVA. In wedding gardens, the estimated emission rate of air pollutants from 250 KVA DG set (running with the average of 3 hours per day) emit 0.183 kg/day of PM10, 3.08 kg/day of NOX and 1.50 kg/day of CO. 62 KVA DG sets produces 0.072 kg/day of PM10, 1.296 kg/day of NOX and 0.77 kg/day of CO.
