GEMINIS–Green Evaluation Methodology for IoT and Network Infrastructure Sustainability

Recent research on IoT, Smart Cities, and Smart Campuses highlights sustainability concerns due to extensive device deployment. This paper proposes GEMINIS, a comprehensive methodology for measuring sustainability beyond traditional metrics to address environmental concerns linked to IoT infrastructure. Existing measures like Power Usage Effectiveness (PUE) and Carbon Usage Effectiveness (CUE) overlook water consumption, electronic waste, and resource utilization. GEMINIS integrates Water Consumption for Infrastructure (WCI), Greenhouse Gas Emissions (GHG), ICT Capacity and Utilization (ICU), and Electronic Disposal Efficiency (EDE) within the cycle Observability → Analysis → Control, aiming to evaluate IoT sustainability holistically, emphasizing accurate data collection and standardized reporting.
