The current hype for product carbon footprints of IT, policy initiatives, such as the European ecodesign directive and several research activities recently lead to the publication of numerous LCA results of laptop computers. A comparison of the various studies unveils a broad variance among the results, which cannot be explained solely by technical differences: LCA for IT products still faces severe shortcomings and methodological uncertainties due to the complexity of the products, and assumptions to be made. This paper addresses the component level in the case of integrated circuits (ICs) to reveal the challenges in the data collection. The paper discusses the various approaches under consideration as reference units for IC-datasets, in order to contribute towards creating a harmonised reference unit of IC dataset.
