Product Lifecycle Management (PLM) systems are professional digital platforms enabling manufacturing firms to facilitate product lifecycle data management—from design to end-of-life. In the context of ecological and digital transition, PLM systems play an ambivalent role. On the one hand, they are implemented to be a solution for retrieving the necessary lifecycle data to enable informed decision-making in designing more sustainable manufactured products. On the other hand, the integration and maintenance of PLM systems require increased Information Communication Technology (ICT) means and organizational processes to ensure the retrieval, storage, and utilization of these data. Environmental impacts of manufactured products are most often assessed, rather than the environmental impacts of the PLM system itself. Furthermore, the intangible nature of the PLM system makes the direct application of environmental Life Cycle Assessment (LCA) methodology problematic. This paper aims to propose and apply Tracking Resources for Environmental and Normative Decision-making (TREND) framework, using life cycle assessment methodology, through a case study: the PLM system architecture of an engineering school. Our results identify the upstream and downstream usage stages of user equipment as primary contributor of climate change impact and mineral and metal resource depletion.
