The cost and stability limitations associated with traditional energy forms, the habits and traditions of residents, and the institution of green policies to mitigate greenhouse emissions are strong incentives to utilize electrical scooters as an alternative form of transportation on islands. The present study originated based on Penghu's low carbon island policy; it assesses the applicability and feasibility of this policy by analyzing both residents' behavior and the electric scooter use characteristics. At present, there are approximately 3,500 electric scooters in the Penghu region. The government has set up 332 charging columns at 27 key locations to facilitate the charging of these scooters. This study adopts a distinct count analysis and drill down methods to identify the characteristics of users' charging behaviors, as well as to understand the optimal placement and numbers of charging columns, users' charging time, and frequency of usage. This study also classifies users into one of three types: “one-time charging,” “repeat charging,” and “high-frequency charging”. Electric scooters in this study have an eco-efficiency of US$309 ($/ton-CO2e), and are able to achieve carbon dioxide equivalent reductions of 5.1 (ton-CO2e/p.a.). The eco-efficiency and charging duration (CD) reductions may improve confidence in the usage of electric scooters, mitigating user concerns about running out of power while on the road. The analytic results of the drill down method and web node provide decision makers with an important reference point that may be useful when setting up additional charging facilities or making changes to current ones.
