Abstract: The reliability and clarity of environmental assessments represent an important prerequisite for measures towards the sustainable transformation of our economic system. Studies examining the environmental performance of reusables are often used to derive arguments for and against their use. Accordingly, it is important to have clarity about the influence of methodological decisions on the results of such studies. This paper analyses possible approaches to the allocation of environmental impacts of transport processes to reusable shipping packaging in the context of parcel deliveries. A model was developed to conduct comparative analyses of carbon emissions (carbon footprint) from the use of single-use vs. reusable shipping packaging and was subsequently applied to two reusable shipping packaging systems currently available on the market. The results showed that using different allocation models led to significant variations in the results for the carbon footprint of the analysed packaging (single-use and reusable), while at the same time, the calculated environmental break-even point in the comparison between the single-use and reusable options remained rather stable. The results highlight the importance of a clear and standardized methodological framework for the communication of footprint information for reusable shipping packaging. Moreover, for determining the environmental break-even point, the results suggest that aspects like the comparison scenario (i.e., the selection of the single-use packaging) are more important than the methodological choice of the allocation model for transportation processes.
