Despite the value of LCAs, data limitations lead to assumptions, impacting accuracy. This study compares an estimation-based LCA with a data-driven approach, focusing on a laser machine's operational phase. The significant influence of resource consumption during operation underscores the necessity of optimization. Applying a data-driven approach reveals a 24% difference compared to the estimation-based method, emphasizing the challenges in obtaining accurate data for effective LCAs.en2732-527X202413391348Cambridge University Presshttps://creativecommons.org/licenses/by-nc-nd/4.0/data-driven designlife cycle assessment (LCA)sustainabilityTechnology::620: EngineeringSocial Sciences::330: Economics::333: Economics of Land and EnergyNatural Sciences and Mathematics::510: MathematicsTechnology::650: Management, Public RelationsConference Paper10.15480/882.968410.1017/pds.2024.13610.15480/882.9684Conference Paper
