Category Definition The aim of this section is to provide guidance for selecting and defining the environmental categories. In this report, the dedicated category can be considered as carbon footprint of the partial systems in terms of carbon dioxide equivalent emissions. Due to the single category assessed within the system boundaries the impact assessment will not be conducted but the section is included in case of future expansion into other categories for the chosen product. 4.2. Classification The classification element aims to assign inventory input and output data to categories. In this case this section is not applicable. 4.3. Characterisation The goal of characterisation is to model categories in terms of indicators, and, if possible, to provide a basis for the aggregation of the inventory input and output within the category. This is also done in terms of the indicator to represent an overall change or loading to that category. The result of characterization is that the combination of category indicators represents initial loading and resource depletion profile. In this case this section is not applicable. 4.4. Valuation & Weighing Weighting aims to rank, weight, or, possible, aggregate the results of different life cycle impact assessment categories in order to arrive at the relative importance of these different results. In this case this section is not applicable.
