Information systems and technology are expected to have a good impact on the civil registration service process including during the COVID-19 pandemic. DISPENDUKCAPIL Surabaya had transformed the civil registration service systems which are LAMPID system into KLAMPID, and KLAMPID COVID system later during the COVID-19 pandemic by implementing the information system. These transformations are proven in reducing the paper utilization and transportation activities which are expected to reduce the environmental impact that is generated by the civil registration service activities. However, those transformations are also proven to increase electricity consumption and internet use since there is information system equipment such as computers and databases equipment which are utilized. This study tries to evaluate the total environmental impact in each transformation by using the Life Cycle Assessment (LCA) approach. The environmental impact calculation results from SimaPro software for LAMPID, KLAMPID, KLAMPID COVID offline submission, and KLAMPID COVID online submission are 24.64 mPt, 41.95 mPt, 41.71 mPt, and 36.81 mPt respectively. This study indicates that the information system implementation was able to reduce the environmental impact from the paper utilization and transportation activities reduction, however, those reductions cannot cover the environmental impact that is generated from the information system equipment.
