The purpose of this work is to point out the importance of the production phase for the carbon footprint calculation of powertrain components and to improve the understanding of necessary data for this calculation. Evaluation of lifecycle assessment data from numerous studies showed, that there is often a shift from the emissions in the use phase to emissions in the production phase, when alternative powertrain concepts are used. Therefore, in this work our focus is on the carbon emissions in the production phase of powertrain components. Data of raw materials used, production processes and supply chains is necessary and the uncertainties associated also have to be considered. At present, there is only little sufficient support for design engineers regarding the collection of relevant data for the carbon footprint calculation of powertrain production. In this work a data structure, which supports the collection of relevant data, including possible data sources, is presented.
