Abstract: In product-oriented Life Cycle Assessment (LCA) studies, obtaining reliable and accurate data during the Life Cycle Inventory (LCI) analysis is challenging due to security concerns of industrial enterprises. In this study, a question catalogue inventory was intended to be developed to obtain accurate data in LCI processes and to overcome this challenge. The LCA process consists of four main stages: "Raw Material – Production – Use – Disposal." Within this process flow, the LCI inquiry focuses on system boundaries, energy, and transportation at each stage of the LCA process. While deriving the questions, the categories of "Definition – Raw Material – Production – Point of Sale and Distribution – Consumption – Recycling – Disposal" were taken as the basis. A total of 50 questions were developed in the study. This study aims to enhance the environmental sustainability of newly developed technological products by applying the LCI inquiry filter during the project phase, in the context of global industrial competition. Additionally, it will serve as a guiding light for those who are new to conducting LCA studies.
